Do you have a Mercedes with an OM642? That's the 3.0 V6 Diesel CDi. It's in the 320cdi or 350cdi bluetec's from 2006. Does your car sometimes stop boosting or it's always in limp mode and won't rev past a certain point or go faster than a certain speed. Check this video out for the most common problems the OM642 suffers from that causes limp mode or loss of boost. If you want to know where you can get most of the stuff I can link it in the comments if needed. Hope this helps you fix your car, quickly, cheaply and stops you from hating your car. Car's that don't work are crazy annoying.
