Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
you say the start / stop is misbehaving can you tell me the sequence of events? doe it just sit there cranking the engine?
the reset of the stop / start needs the use of the Mercedes STAR software so even if you had the procedure you'll still need to invest in the software
however there are a few things that can stop it form working
If one of the above conditions is met it does not allow the start stop feature to work.
so I'm wondering if your dealer has investigated all these? or are they just doing a reset and sending you on your way
as if the engine has a vacuum leak then this can come and go with temperature
I'd go back to the dealer and present them with this list and ask have they checked them all
