This one is becoming a minor saga. Two services back I asked my dealer to re-synchronise the service indicator to match the service type (A or B) indicated by the logbook. Somehow the two were not in agreement. This meant when ASSYST was asking for an A service (one spanner) both I and the dealer agreed a B service (two spanners) was due. I had the B service done.
After I got the car home I noticed ASSYST showed the next service would be the B service which had just been done!
I rang them up and was told they hadn't been able to resync the indicator, but agreed to look into it further.
Months passed. Time for the A service. ASSYST was still asking for a B service, of course. Got into the dealership today and discussed the issue (again) with them and was told they would sort it during the A service. Got the car home and presto! the ASSYST display indicated the next service would be the A service, which it had just had, not the B. Got onto the phone (sorry, we're nearly there) and was told that the snagged item had not been forgotten, but that as an anti-tamper measure M-B had ensured the ASSYST display could not be made to change an A service indication into a B service (or vice versa) even by the dealership.
I asked that if this were so, how did it get out of sync in the first place? It seemed to be common sense that what can be rolled forward once, accidently, can be rolled forward twice and thus re-sync'd! The handbook even states, "The service indicator can be updated at a Mercedes-Benz Service Station if it has been inadvertently reset."
They said they would get back.
I understand from the dealer that if the interval between services exceeds a certain mileage (I've been variously told 13,750 and 16,800) that a B service is required by default. So it is perfectly possible to have two B services in a row, although this did not apply here as the mileage interval had not exceeded even the lower figure in either case.
One thought occurs: if the car should have got two B services in a row at some point in the distant past, but instead was mistakenly given an A service by the dealer on the second occasion, this might explain the apparent discrepency. PERHAPS the only way back is to give the car what it is asking for (not what I think it ought to have!!) i.e. another A service next time around. Or better, two B services in a row
Question is, has anyone else encountered this little 'reset' problem and if so, is the dealer right about their inability to reset? And if he is, does that mean the car has been receiving the 'wrong' service all along? Or am I just confused??
