Perhaps THE definitive source of Mercedes Info for repairs:

www.MBWholesaleParts.com

when the site opens, go to Startuned link or just meander around. I've had a subscription since Vol 1 No 1. Its really well written.

Has repair theory for independant MB techs...Some of the best written mech help I've seen in over 35 years of reading tech mags and manuals... Happy New Year to ALLLLLL!!!!
