Reset service indicator C300 C350 C63 Mercedes 2008 2009 2010 2011

How to reset service A or B indicators on your Mercedes C class, useful when you change your own oil.

[@SuperDnice69]

FYI....I tried and tried this over and over...After looking through tons of blogs here is what worked for my 2011 C300 that had the "A3 service is over 100 miles" message. You need to push the "phone" button first, then while holding it press "OK". Hold both together for approx 5 seconds then follow the rest of the instructions as listed. The issue for me was NOT pushing both at the SAME time. Phone first, then OK and both for 5 seconds. Hope this saves some blood and sweat for everyone!!!! :)

[@sabrinavirk702]

Thank u!! I was getting so frustrated

[@TheCaramelDime]

Dominique S thank you

[@molmsikop5056]

This worked...i have no more constant annoying messages ..thanks

[@tekphase]

Thank you. How did we ever live without the internet and youtube?

[@ronwillis8116]

Thanks so much for this info!!! I Just paid a Mercedes repair bill of $127.00 out of pocket for an oil change and $200.00 deductble for warranty services, and I left that shop with the service light reading 1100 miles past due!!!! I won't be going back.

[@sirbiz336]

Thank you! Finally after 6 months someone show me how to reset that darn thing! 🙂

[@randall928]

Glad it worked for you!

[@mattman6161]

In case anyone has a Canadian car, you must remove the push to start button, and then insert the key and follow the process. The button just pulls right out with ease. Also pressing the phone button first and then press ok and hold till the screen pops up worked for me also. 2008 c350. Thanks for the vid, could not figure this out for the life of me.

[@jackstan32]

Wow! This absolutely worked for the 2009 C350. Other videos have not worked and the manual is terrible. Thanks alot for this. Finally!!

[@joeserb1111]

Got mine to work as well! You do have a half second pause before pressing the OK button. Worked great! Thank you!!!!!!!!!!!!!!

[@JRproudDad23]

Btw, in my car , I had to hold down the 📞 button FIRST then simultaneously hit and hold the OK button to have the secret menu to come up. if you do the 📞 and the OK button at the same time, you get reset trip odometer option... Great 📹 regardless!

[@vetten76]

Outstanding. I was staring at that service overdue for a month. Great video. Thanks for the help.

[@JB73691]

Did you do the service or just got rid of the message ?

[@Tallredhead11]

Thanks for great directions and the extra important clue you provided, which was to start out on the "main display- the regular odometer menu". At first my car wouldn't display the regular odometer because there were other messages showing but I was able to clear them by pushing the OK button which then allowed the main display to show. Then I followed your directions (ok, it took me a couple of tries) It worked! Thanks so much for helping us stay free of overpriced dealership service centers!

[@ydiaz603]

Worked on 2012 c350. When pressing answer call and ok button you have to first press the call button and while holding down press ok button for about 5 seconds. Secret menu will pop up... If you press both buttons at the same time reset trip odometer will come up.

[@curtn.8409]

odometer must be reset first then follow those steps. Works out great. Thanx, uploader

[@BobFM1795]

Thanks Randall, you saved me $300 bucks on a $60 oil change! And now my wife doesn't have to drive around with that stupid message on the dash.

[@desireeperkins3848]

Just tried this and it worked!!! Thanks sooo much!!

[@jentodd31]

just did this and it worked, thanks so much! what would we do without youtube, lol

[@randall928]

begin with door closed, key not in ignition, insert key, turn key to position 1, make sure you are on the home display(not the mpg display, etc.), push & hold the call answer, then 1/2 second later hold down OK button, hold both until the hidden menu appears

I have a 2008 Mercedes C350 with 3534 miles. I have been unable to reset the Service A or Service B warning indicator. Over the years, I have had my car in the shop and the service Advisors have attempted to reset it with no joy. I suspect there is a bad control module, but which one? I had an independent repair shop try resetting it with their computer, but also no joy. It seems to register the warnings, because it used to show the Service A was past due, then it changed to the Service B was past due and now indicates something like 530 days. As I said, no one has been able to get it to go away permanently until the next service is due. I can get it to go away temporarily by hitting OK, but the next time I start the car, it comes up again. Any idea what has to be done to fix it?

[@bertito147]

Thanks!!!!!!

[@MrDumbdog21]

Does this work on 2012 c300?

[@joekane4112]

Anybody know how to take the battery light off? 2008 c 350, new battery, alternator checked out fine but light is still on.

[@SureshKumar-wb6kk]

I tried it on C300 model 2008 and didn't work. it goes to odometer resetting only. any suggestions.

[@user-vv2sv4tr8o]

Tack

[@michaelh2528]

Tried it on the 2008 C300 model it keep prompting to reset the TRIP ODOMETER instead

[@elche2124]

those the same thing to my 2009 c300

[@neilrd2115]

Have to press the call button first then ok button

[@randall928]

Try to follow the services listed in your owner's manual, but most can be done yourself, such as oil, air filter, cabin filter etc. Transmission fluid is difficult to do yourself, best left to the professionals!

[@armenkhachatryan1041]

Thank you it's worse in my Mercedes 2011 E350

[@covochy]

Thanks u . save me $

[@lanniehernandez1832]

I'm not sure why it does not work, I got all the way to Assyst Plus but it did not take me to the next step to click full service etc. Am I doing it wrong?

[@krulzy1]

me either did you work it out ?

[@kokobrown5459]

What about abs inoperative

[@dpac3d]

What is the A3 service indicator for?

[@randall928]

Synthetic Motor Oil Replacement Oil Filter Replacement All Fluid Level Checks & Corrections Are Dependent On Factory-Recommended Service Intervals For Your Vehicle's Year & Model Tire Inflation Check & Correction Brake Component Inspection Reset Maintenance Counter

[@NgocNguyen-ku1nl]

What is the A1 service indicator for?

[@randall928]

The main point of A1 service is to change the oil and filter, you should also check all other fluid levels and check the condition of your tires and brakes

[@josefsison3233]

Do we really need any of these services? I think mine says that I need an S5 service or something. Are these services really are more of a ploy to make money or does it really have any relevance to the maintenance of the car? I would appreciate it if anyone could answer these questions. :-D

[@teebone5072]

make sure the door is shut while you are trying this or it will not allow you to go to the setting menu when pushing the controls.

[@rochellestrong3824]

this is not working for my 2009 c300

[@Spertrun]

Did not work for me mercedes 2009 c300

[@poetheraven01]

Doesn't work on my 2008 C350. After getting to the confirm and can't be undone indicator and pressing confirm, I get a message saying it can't be preformed.

[@carlostorian1441]

I got the same thing

[@jessechen2701]

Seems to do this if you do not reset or service for too long. I think ours says 940 days overdue. Trying to find more info.

[@rochellestrong3824]

what am I doing wrong?

[@randall928]

Try holding down the answer call button slightly before holding down the ok button.

[@billbog25]

The damn odometer reset keeps popping up. Frustrating

[@fangxinhan9251]

It does not work with my c300 2011. No secret menu pop up at all...

[@hales2363]

Fangxin Han mine neither.....

[@Stephenthegreat20]

Keeps saying remove key from ignition

[@alaneisner5739]

It does not work....I get to the last screen and then it says.....COULD NOT COMPLETE SERVICE... I tried many time ???????///help

[@randall928]

Hi could you share a video? I'd like to see 🙈

[@robertseitz3355]

What is service A3

[@randall928]

This includes, oil change and filter, air filter, flush the brake fluid and re-fill, check brake rotors and pads for wear, replace cabin air filter and reset the service interval on the computer. Not sure how useful the brake fluid flush is, adds a ton of cost at the dealer.

[@jamarmckay5514]

Mine stays on take your key out

[@EVEsystems]

no work. sometimes it asks me to pull the key out in position one or sometimes when I hold the buttons it just asks to reset the odometer. nothing more happens. Problem is someone need to actually make this video WHILE having a warning message for over due days.

[@someusername121]

I don't even own a Merc...why am I watching this?!?!

[@ErikGretland]

Thank you
