Service "A" is the first service interval and if this hasn't been done, you need to take care of this now. If this service was done and the interval was not reset, go back to the mechanic and have it done; it takes about a minute, and you should have this mechanic's failure brought to the attention of Mercedes management..... If you want to do this yourself, not recommended, you'll find the procedure on line; just google your car. The procedure is somewhat involved.

GET THE SERVICE DONE ! if it was done at a dealer and they didn't reset it,you should get free coffee for life for this basic error. If you want to reset it yourself, the instructions are easily found on the web or one of many MB forums. It's tedious, but not hard. UNDER NO CIRCUMSTANCES RESET IT WITHOUT HAVING THE SERVICE DONE !. You're asking for trouble and lower resale value without a documented maintenance history
