The car has 120k miles on it. I've decided to go ahead and purchase the vehicle. My mechanic has been the one servicing the auto for it's entire history and has thoroughly gone over it for me.
It will be my third Mercedes and I've had nothing but positive experiences. I'm guessing that if the problem is the EGR I'll know when I try to drive more than 20MPH.
How do I get to view the fault codes? Do I need a special reader? I'm guessing yes.
Oh yea, the wiring harness has never been replaced. Cam cover gaskets have been replaced and the head gasket shows no signs of leaks. I think I'm in pretty good shape. Hopefully I made the right decision.
Thanks for the help.
