How to reset, Mercedes Benz A-Class Service Indicator

How to reset your Mercedes (W168) A-Class Service Indicator.

Livedrive Cloud Storage

This page is for information only, I am not Mercedes Benz so if this doesnt work or you have other problems go to Mercedes.

If you cant get it to work, you arent doing it right!

If you do decide to use this information then you do so AT YOUR OWN RISK.

PLUS, this only applies to the W168 Mk1 and Mk1 Facelifted A-Class only, IE: A140, A160, A190 & A210 Petrol and the A160CDI, A170CDI diesel engine models.

That is the model below

This will not work on a W169 model which is from late 2004 onwards!

So please stop emailing me saying it doesnt work if your motor is newer than late 2004! It wont work as its only for the earlier A-class (W168) model.

The how to reset the Assyst, Procedure.

  1. Turn the key to position 2 in the ignition lock and immediately press button 000.0 twice within the space of one second.

  2. Turn the key to position 0 in the ignition lock.

  3. Pressand hold button 000.0 then turn the key to position 2 in the ignition lock, Keeping button 000.0 pressed, dont let go!!!! You will hear a beep.

  4. The service message with current remaining distance or remaining time appears. Keep button 000.0 pressed!!!

  5. After about 10 seconds, an acoustic signal will sound and the service display with the new starting distance or starting time appears for about 10 seconds.

  6. Now release button 000.0

  7. Thats it youve reset your service indicator.

If this procedure doesnt work first time its typically because you have let go of the 000.0 button at some point. Try again.

Additional for Vaneo and maybe W169???

Rich Hall writes: My recently purchased 05 Vaneo requires me to press the "+" button instead of 000.0 to reset the trip.

The above original instructions failed for reset the service interval but when I tried the instructions but using the "+" button instead of 000.0, the service interval reset perfectly.

I hope this helps others.

Thanks Rich.

Ive also found this within about 10 seconds of searching.

Wasnt hard to find!

PLEASE NOTE: if your going to leave a comment below, please remember:

I AM NOT MERCEDES BENZ. If I was I wouldnt be telling you this!

I AM NOT A MERCEDES MECHANIC/DEALER! If I was I wouldnt be telling you this!

I DO NOT HAVE THE KNOWLEDGE TO FIX SPECIFIC PROBLEMS, if I did i´d be charging you £100 an hour labour!

and I DONT CARE ABOUT HOW ANGRY YOU ARE BECAUSE YOUR ABC or XYZ HAS BROKEN but I MAY help you if I can and if you ask nicely.

If your Annoyed with Mercedes go to the dealers and shout at them, not at me!

ECU light on dash A class 140
Hi all

Can anyone help,i know this is a problem with the A class but the ecu light is on in the dash and the car is running great,iv had it reset at a garage but it still comes back on after a day or its running ok which is the fuse i can take out so it will go out.




mykp says:
get the error code and get that checked. Just pulling the fuse is a recipe for disaster. Get it checked by mercedes as it maybe a more serious problem

Hi. I have a 2000 M-B A160 automatic transmission. Suddenly, there is no information in the ""display"" in the instrument cluster. Have checked fuses & all ok. Any suggestions on how to resolve this? Cheers

A160 automatic (2000) -

I just came across this forum when browsing re: a ""hiccup"" that occured yesterday:

While driving I had the impression that there was a grinding/rough sound when the car was moving.

Later that day when waiting at a traffic light, the ""D"" indicating the gear in the dashboard screen changed to ""F"" and the car would move as if in 1st gear with handbrakes on.

As the traffic light turned red again, I could stop and turn off the engine. After that, all was back to normal.

Furthermore, the SRS light was visible for a few seconds when turning the car on. Maybe I just never realised before. Anyway, the light disappeared for good.

Thank you for your help.

could be the battery? how old is the battery?

vibration in first gear when starting off
Hi. I recently bought a 2004 A160 automatic (which is overdue a service by 11400kms), and im hoping you can help with my issue. Whenever I start off, the car vibrates and revs when i give it gas, but it barely moves. It then runs smoothly and properly once it changes to 2nd gear. I ve tried starting off in a higher gear with the tiptronic, but this didnt help.

*Brilliant Advice*
I have just reset the service indicator on my 2001 A160 Elegance & it worked, many thanks.

I also have an SRS light on, any ideas about how to turn this off? I m sure there isn t an issue.

Many thanks

mykp says:
SRS can only be turned off by an OBD reader / resetter which you local mechanic will have but it might be a deeper problem so best get the error code read.

A160 Stiff Steering, HI alarm, Alarm jams on, interior light
Thanks for a bunch of great advice. Here s my 5 cents worth .I found that the steering gets stiff as the revs fall and traced it to a blocked breather ( collapsed rubber oil contaminated jellyish) hose and it fixed the problem after replacing hose located on Rhs(facing knees against bumper) of engine.

Interior light not extinguishing also was corrected cos back door was not fully engaging striker plate and needed aligning.

Hi oil light comes on if you do extreme braking or acceleration when the dipstick show normal full position as the oil sloshes onto sensor. if it is too full you have to drain exceess oil.

Thealarm continuing to go off I traced to a stuck relay. reset it by cleaning the spark eroded sticky contact points after removing relevant relay and fuse( use the paper insert to locate the alarmrelay then use a sharp flat screwdiver to pry the plastic cover open and voila the coil and armature/points will be seen and can be serviced

brown gunge in the oil cap can be condesation mayonaise on a high milage unserviced car and not a blown head gasket, mayonaise on the dipstick is another story, which will need you to flush the engine (sometimes twice, pull the cylinder head and skim clean and replace the seals/gaskets and filters as per service requirements

I have a V reg A160 and love it. Is there a way of disconnecting the imobillizer? I have a small red thing attached to the fob which I assume is what I use. But dont know where to disconnect? Thanks in advance.

there will be a socket somewhere to plug it in. Usually in the glove box or down by the footpedals

Hi I have had an A190 for about a year. I have figured out most things in it without a manual, but what I want to know is: what does the switch marked S at the top and W at the bottom, beside the auto gear change column mean? Every now & then I switch from one to the other, but don t notice any difference.

mykp says:
S and W are summer and winter, W makes the changes longer between changes

AClass keeps going into emergency mode
I have a 1998 Avantgarde which keeps going into slow mode, BAS comes up on the dash and despite having spent over £1000 trying to rectify the problem It happens again and again sometimes a few times in a row then it doesn t happen again for a while. Today I had to pull over 15 times on the way to work on the way back it didn t happen once. Usually when I turn the engine off and start up again it runs fine. If you have the time please would you be able to shed some light on what the problem might be? Thank you.

mykp says:
no idea sorry but I think you need to get the error code in the memory checked and any local garage should have the kit to do this.

A180cdi( w169) crazy instrument panel shows phantom faults !!
Help, took out battery and charged up and replaced it, fine. A week later display panel showed check coolant fault so i checked and coolant was fine ! and fault has stayed on .

Today, whilst driving panel showed ABS fault and then ESP fault 5 seconds later and then accompanied by the fuel guage dropping dead and showing no fuel . Even the reserve light was off ! Upon applying the brakes i could feel the ABS working fine !

I got home turned engine off and then turned ignition on and ABS and ESP faults were off and fuel guage sprang into life !

Satisfied that it was my imagination ,i started the engine and behold faults returned and fuel guage died again !

is my car haunted or have mercedes built these in to fleece customers of shed loads of cash !!

Any advice , miracles appreciated

No high beams and dim dashboard light
Hi, I own a 2001 Mercedes A160. It has low kms and has been cared for very well. On my last service I had the light bulbs replaced and on its return, the high beams don t work. Initially I thought the wrong bulbs had been replaced or something, but if I flicker my high beams, they work. So when I need to use them, I have to hold them on flicker , otherwise when pushed forward into high beam position, they do not work, just stay at the normal light range.

Second problem - yesterday my dash board lights suddenly went dim. They are virtually impossible to see during the day, but at night time when the head lights are on, they appear faintly. The dashboard lights which are dim are the ones which display kms, trip meter, temperature, time and gear . I read a previous post which suggested to use the + and - buttons to adjust the brightness, however this does not work.

Can anybody help me with my two problems?

mykp says:
it sounds like you have a fuse or relay issue. Difficult to diagnose though!

Hi i hope you can help me or even have any ideas about my problem. i drive a 1998 1.4 manual A class and recently the reverse lights stoped working so i found out that i should replace the switch. i changed the switch but now the lights are always on (even if i now put the old switch back in). ive looked into the hole and there seems to be a selector/mechanism that does not move and is off centre and this seems to be holding the switch in. Any ideas would be a great helpThanks

Hi there, glad I found your site.

I have an A170 Avantgarde 1999 diesel semi-automatic. In the display section on the dashboard where it usually reads which gear I am in (1-5) it just displays an F I also have the ABS & ESP warning lights showing and it would only drive about a meter then not let me go any further as if in saftey mode.

I saw a lady before had written about the F sign and you advised her to check her battery. I took mine out and left it to charge, it took 12 hours to get it fully charged and now it drives but is very jolty, however the F sign is still there whichever gear it s in. This did happen once when I was on the motorway when it suddenly lost power and displayed an F but hasn t happened before when going slower then 70 mph - until now!

Do you have any idea what could be the problem? Any help would be so much appreciated :)

mykp says:
if other warning lights are on then i d say something more than a battery is at fault here

Start Error on A190
Strange one.  My wife s Mercedes A190 has had intermittant START ERROR messages. We replaced the battery, but it didn t seem to fix the problem permanently. Auto elec recommends starter motor (YUK)

However, whenever I start the car with my (spare) key, it starts every time.

Could it be as simple as a faulty key (immobiliser)


mykp says:
could be the transponder in the key. A starter motor replacement is expensive as well so i d look at the key first.

Mercedes a class 160 elegance

I just got an A160 Elegance 1999 T reg. I have a few issues and any guidance would be a massive help! Firstly the steering wheel has the tendancy to get heavy, as if the power steering goes...usually when Im parallel parking or doin a 3point turn! But when i turn the car off and on again its back to normal, but this is obviously not very convenient. There seems to also be a creaky sound when turning too. And finally when im in traffic i cant really hold it on a hill as it judders in 1st gear.

Do you have any guidance or advice please?

mykp says:
Steering, change the oil first, if its still bad then the power steering pump is on its way out. Juddering is probably clutch related. The creaking noise might be related to the power steering.

Vaneo works pressing
My recently purchased 05 Vaneo requires me to press the ""+"" button instead of 000.0 to reset the trip.

I hope this helps others,

Cheers mate. Only bought my A140 yesterday and I already know how to reset the service counter!!

A Class 07 plate
Could you please tell me if most or any instructions for repairs relate to My A Class A 150 07 plate, because i have got that model and I cannot seem to find any info about the w169 series, even Haynes do not make a book for that model.

I am asking you in good faith for this info because I am retired now and I do like to do most of the minor maintenance on my car, and try not to go to Merc agents who are far too expensive for me all I want really is some basic info as to what goes where and be able to rcognise some of the parts .

Hoping you can help me.


mykp says:
Cliff, I know nothing about the W169 model a-class as i ve never owned one. What I will say is that you enquire about parts prices at mercedes benz as the prices for consumables for my A210 where quite cheap. EG: Front brake disks where £23 each.

-5500 sign on the dash of A160
Hi, my  A160 2004 shows -5500; what does this mean? is it over dure for 5500 kms? how often should it be service

It s really good having ur advice on this web


mykp says:
depends on how the dash is setup, I think the W169 models where setup for distance not time, otherwise your service indicator is 5500 days over due which means it was due a service 15 years ago which is 9 years before it was made. But this wouldnt surprise me if it was days. either way its over due a service.

Reset Windows
Hi, i m Cristian from Argentina

i haven t tried this trick yet, but i think you could help me..

i ve been looking for some help in the web, but no one answered :(

i ve got a 1999 A160 Elegance, and i m trying to reset the windows computer. it has electric windows (or whatever you call it :P) in front and back too. none works, not from the center console (between the front seats) and neither from the doors in the back. not even a little noise nor nothing.

i ve cheked the fuses and they re all good. so i think that could be the problem.

and more to say, it passed a long time (almost half a year) without a use... i wasn t able to use it cause i wasn t at home :S so in those months the battery died.. i think that turned off the computer and disprogrammed the entire system :P

i m in a little trouble right? :)

hope you could help me, it s just the windows problem. nothing else :)

thanks :)

Unable to lock doo and inner light does not go off

Out of the blue my CDI 170 would not let me lock the doors when I pressed the key. I checked the key and battery and it s still not locking.

Also the light that comes on inside when you open the doors and will not go off at all, even when the doors are all shut. I have to end up driving with the light inside on. The only time the light goes off eventually is if you continually leave a door open.

Please help!

Thank you

mykp says:
Angelique, its either the door switch is defective, maybe a loose wire or the door locking mechanism is faulty. To test the door switch its a simple case of finding it, its a little black rubber squidgy bit which when press will move in and out in the door surround. The later can be tested by pressing the door lock button underneath the hazard warning light. If its the switch swap it for a back new one. if its the central locking then check the pipes which lock the doors, the main controller is next to the spare wheel and has yellow pipes going to it.

Service A160
Hi i just wanted to know how often should  my car be serviced i have a A160 Advantguard.I serviced it last year and now the beeping sound is on again

If i turn the beeping sound off using the method u said previously, without servicing it ,what will happen?


mykp says:
John, The Mercedes Assyst isn’t always right, but Mercedes say "you can should be serviced every 12 months or 12,000 miles. Which ever is soonest" On two of the tree a-classes I have had the assyst counts down in miles until 10 months after its serviced the it changes over to days. On one the assyst would kick in whenever it felt like it, no reason as to why but 6 months and it was on again. If you reset it then nothing will happen, it will just revert to 12000 miles or 12 months. A few checks might be advisable, such as checking oil colour and levels.

I have only had the car for 4 days( bought second hand with no manual) and stupidly thought well ill just open the door manually which obviously set the alarm off!

 I have replaced the batterys in the key and it still dosent work the doors. I managed to stop the alarm going off when the doors are open by turning the key in the drivers door left rather than right but as soon as the key is in the egnition and the engine starts the alarm goes off again!!

A140/168 - success
Way to go, man - most helpful. Mine was showing one spanner with -28900, i e: I am very happy to get rid of this c**p. I have an A140/168, 1999-model. In my case it worked by doing exactly as stated on top here. In other words, in my case it did t work with waiting until the current service indicator shows before pressing the 0.000 twice. I pressed it directly after swiching the key the first time.

For those who struggle. For me it was very important to press the 0.000 twice very fast. Before swiching off the key again, there was a change in the display. This showed me that I was on the right track.

S**k Mercedes.

It Does Work A160
Just in case anyone else out there has a sore finger from trying this over and over again, I found that the timing was important in my case.

As one poster stated wait for the current service indicator to appear (in my case 2 spanners) and then press the 000.0 button twice quickly.

Immediately turn back to position 0 (the service indicator should still be on the display), then press and hold and move to position 2 as described.

Tried a number of times but the time that worked was when the spanners were on the display the whole time.

engine management light 2002 A60 mercedes
hi just had the same problem with my A60, the battery was almost flat, it just started, and the Engine management light came on, recharged the battery, gave it a good run, but it,s still on, please can you give me some advise on how to remove the warning light? it would be helpfull, as i use the the car regulary to take my dissabled wife to Hospital. many thanks Roger.

mykp says:
If the engine light has come on the welcome to the great Mercedes con. I ve had this on all three of my A-classes. The only ways to turn it off are either

1. buy a diagnostic reader off ebay, making sure it will also clear faults and use it on your car.

2. take it to Mercedes and pay £43 plus vat to get it switched off.

The check engine light is there as the ecu is assuming, wrongly!, that there is a fault as the car struggled to start. Even leaving the battery off over night will not get rid of the check engine light as the fault is logged in the ecu and the only way to remove it is to cleat it with a diagnostics reader.

Your not on your own as I ve been asked this lots of time and just had the same problem with my A210. Hence why I bought a £23 ecu reader of fleabay.

Sorry cant be of more help.

HI on my odometer

I have an HI comunicate next to odometer in my A160. Can somebody please tell me what does it mean? car is registrated in 1996  1.6 petrol.

Many  thanks in advance

mykp says:
The HI means that the oil is high in the engine. Have you had it serviced recently, if not it could be the sensor is faulty. No idea where the sensor is or how to replace it as I can only advise on the A-classes I have owned. Sorry I cant be of more help. mike

Mercedes A class oil level switch
My A 170 suffers from nuisance oil level warnings (oil level ok) when driving. Can you please tell me where the sensor is so that I immobilise it or replace it.  Many thanks

mykp says:
No idea, not a mechanic and knowing Mercedes Benz its probably integrated with something else so you cant disable it! However it might be a faulty sensor?

Please help!
I just bought a second hand A160, w168. i hope i can get some help from here. there are 4 push buttons beside the dashboard. it seems the one under 000.0 is for switching between displaying temp and time. the others are making no sence to me, tried to play with it, nothing happened. any one please help!

mykp says:
The 000.0 button will do 3 things,

1. reset the trip computer
2. tell you the distance to the next service and whether this is an A or B service
3. reset the service indicator

On the other side the + and - buttons let you adjust the clock and they also adjust the brightness of the dials when the lights are on.

Posted by: Wilson on 18 October 2009

What does the button with a hook and seemingly towed vehicle on it actually do?

mykp says:
it turns the alarm off to various stages. IE: press it twice and it disables the interior sensors so you can leave you wife/dog/kids (delete as applicable) in the car and lock it.

benz a160
I ride a Benz A160, on my dashboard is now a spanner symbol with a reading which is now at -3900. This symbol wt the reading only shows when i just ignite the engine. It will beep for some seconds and off it goes. I just did the servicing on the 1st October,2009. What could be the problem pls?

this gives me a serious headache.

mykp says:
Sounds like the service counter needs resetting. If you follow the procedure on this page: This will reset the service indicator back to 10,000 miles and will turn off the annoying beeping.

It works, but does not solve my problem
I have reset the ASSYST on my a 140, but my problem still continue. If i drove my car above 60 km/h, the BAS ESP lights on, after 15 or 30 minutes of driving, the car tremble and shutdown. I can only restart the engine after 30 minutes.

mykp says:
This is a not a cure all for problems in the ECU. It only resets the service timer. I think you have something else wrong and would consult a mechanic.

2006 Reg56 A class
It did not work for my 2006 Reg56 A class, any comments.

mykp says:
This ONLY works on W168 models or Mk1 a-classes. if you have a 56 model then yours is a Mk2 or W169.

mercedes e class 2005 cdi
hi there i have 2005  mercedes e class E220 cdi when i switch the ignition on i get a beeping noise only for 2 second or three second.this hapen when i unpluge the head unit?if someone know something please post it thanks

mykp says:
knowing mercedes its a security feature. Dont know anything about it though fella!

Posted by: sonila on 21 July 2009

I have a mercedes a140 and when i switch on the ignition i see on my display little spanners with the number 29 next to it? im not sure what this means? please help

mykp says:
this is telling you that you have 29 days left to your service, its part of the Assyst system, which monitors the engine and servicing schedule. If it beeps it means you should have had it 29 days ago.

As you only have one spanner then this is an A service, 2 Spanners is a B service.

I would also say that its probably wrong as all three a-classes I have had have counted down over 12 months, not 12,000 miles. My A210 told me it needed a service after doing just 1800 miles in 12 months.

Service reset
Hi i have a 1999 a160 auto and i have tryed to reset as instructed i get the beep sound but it wont reset

is pos 2 just before start or is it one back??? there are 4 buttons on dash 2 on left 2 on right ??

mykp says:
Position 1 is keys in and accessories on.
Position 2 is just before starting with the dash lights on
Position 3 is engine started.

The Buttons you should be pressing, are the left ones. They have the Clock/Temp or Mileage/trip on them.

Many thanks,that worked .The only comment is that you need to wait for approx 2 secs for the current service interval to appear on the screen before pressing the 000.0 button twice.Brilliant.
