that did not work for me it says service is over due now

 

I am a newcomer to MB and this forum. I recently bought a 2003 C240. Being a DIYer on my Lotus, Porsche and other stuff, I wanted to be prepared so I purchased a simple device with a 38 PIN connector for resetting the service reminder and airbag light. Was this necessary? Do the dealers use something like this? Do any of you use something like this?

 

This has been added to the AFTERMARKET/DIY sticky for future reference.

 

problem... this worked for me but I can't change the reminder to Service B... It said service B but I just did early oil change my self so when I reset it, it only goes to service A remind. How do I get the B reminder?

 

Just do it again.

 

doesn't work, I did it 30 times still shows service A

Can anyone guide me how to get the service B reminder?

This worked for my 03 C230K

ignition on, not running
Remaining miles to service displayed
Press and hold the dash reset pushbutton
(ask you do you want to reset)
Press and hold the dash reset pushbutton
DONE

Thank you.

 

I purchased a simple device with a 38 PIN connector for resetting the service reminder and airbag light. Have any of you used one of these?

 

It really works ( It works on mine 2003 C240 4MATIC) but the only thing is that the steering wheel buttons may not be working properly so you have to push it hard
At one point I think they didn't work but you have to push it hard.
also when you turn the key to on position you have to wait about 1 minute
Good Luck

 

Old thread, but noticed no one had posted the newer process.

 

Sorry to bring this thread back from the dead but its probably better than starting a new one.

I followed the directions in the PDF and it works great with one problem, when I get to the oil type menu it is set to "QF 1.0" and if I press the volume keys (or any others) they do not change that setting, the volume just changes... maybe my car only has one setting - "QF 1.0" ?

What is QF 1.0 ?

It's a 2005 C240 4-Matic

 

2007 C230 .. with 8,500 miles.

I also am having trouble right now with the Reset. I followed the directions in the PDF to a T and was able to remove the service B overdue message to service A in 13,000 miles. However, I started driving around and the 13,000 miles hasn't started ticking off. I have drove many miles and it keeps saying 13,000 miles. Additionally, I want it to say service B due again and not A. I tried repeating the steps to reset that I did in the first place and it keeps saying service A due in 13,000, not B. ANy ideas?

 

does this work for a 2005 C55?

 

I just reset my service display as described in several threads and now the engine will not start anymore, not even crank. All lights etc. still work. (2003 C320 wagon). Any ideas what happened or what I can do?

 

i guarantee you that resetting the service display had nothing to do with your car not starting. ok first off any error in the display? how old is your battery? have you ever replaced your cps? how many miles on the car? did you do anything else besides reset the service thing?

 

I assume it is still the first battery. I bought the car in 2005 and have not replaced the battery. I have never replaced the cps either. The car has about 78k miles on it. After I covered the problem this morning I waited about an hour and tried to start it again. The engine cranked twice slowly but did not start. Now I thought it may be the battery and I connected a battery charger. When I tried to start the engine 1p minutes later it stared right away. So it seems to be the battery. The strange thing is (and that is why I did not think of the battery in the first place) I drove the car a short distance about 10 minutes before I did the display reset. And 10 minutes later it would not crank/start.
Thanks for your help anyway.
Final question: how often do you need to replace the cps?

 

ok read this before you replace the battery https://mbworld.org/forums/c-class-w...g-battery.html. i don't want to see you on here tomorrow with a blown sam. lol second i would replace with Mercedes battery because they last forever lol. alot of member on here have called roadside assistance and they will put the new battery in for the cost of the battery. you have to live near a dealer i guess though and i think not be able to start your car. but i don't really know if that is true or not. i would recommend that because if they mb guy blows the sam it is not your problem and the early Mercedes seem to love to do it. as for the cps i have no clue but if it hasn't been replaced yet i would order one online for like $50 and do it now so that you don't have the problems so many others have had. i think it was C230 Sport Coup that found the really cheap place to get it. i will be ordering one very soon for my c320 because it has 136,500 miles and it was done at about 85k last. hope this helps

 

Need instructions for reseting service indicator light for 2008 ML 350.
Big "D"

 

Wrong forum. Pose your question in the ML forum. This forum is for w203 models (2001-2007).

 

What is cps? Is it an acronym for a certain part?

 

crank position sensor

 

1. Ignition key in position 2.
2. Use the page button to select odometer readout in cluster.
3. Use the scroll button to display FSS indicator.
4. Press 'R' button on cluster for approximately 2 seconds.
5. Display in cluster will advise "to reset service reminder - press 'R' button for approx. 3 seconds.
6. Press 'R' button on cluster for approximately 3 seconds.
7. Service reminder is reset.
