Dealer A or B maint
thank you




Not sure where, but also read that service must be accomplished to Mercedes-Benz Service Center standards and use of non-MB approved parts may adversely affect vehicle.
As Konigstiger says, make sure you document it throughly and that they do everything listed in Maintenance Booklet.
Legally, MBUSA has to cover warranty if work done by owner or qualified technician, but will it give them a reason to question covering something?
Manual also brings up several notes re: the various computer interfaces and how important it is they be maintained to M-B standards.
Read Operator's Manual, Maintenance Booklet and your extended warranty carefully.
