Wish M-B would be prompt in correcting the errors in their information system - from vague arrows pointing in the general direction of the right rear of the engine compartment (where the ECU ISN'T), to not fixing inconsistencies where the ECU IS!
Makes me considerably less comfortable working with the system - and a LOT less likely to pay a dealer $130/hr to waste time with a system that shows stuff that isn't there.
Wife still has the car - so no progress to report.
