2010 C300 - How to reset service message
 

Hi,

Can someone tell me how to resent the ASSYST PLUS message regarding Service A?

I have tried the procedure for earlier model years, but apparently the system was changed in 2010 because the displays are different and earlier instructions don't work.

Thank you.

Here's the MB reset instruction
 

Note: Make sure that you close the driver's door behind you BEFORE you get started!

I found that if I reset it before it was due all went well. When I waited until it was overdue I had to have it reset by the dealer.

Much appreciated.

Thanks,this worked perfect

I did all the steps, but at the end I got the next mesage:

I dont
 

I dont have the keyless start button.
