Hi guys,
Last couple of weeks my E320 CDI 2006 makes me a crazy. First I went in limp mode couple of times and I had to repair my actuator on turbocharger. Everything seems to be fine for couple of days, and today when I was driving back from job, my car started jerking and I lost power. No lamps on dashboard on !? Car was going but between 2300 and 2500 rpm car was jerking. Definitively I felt my car doesn't shift well and doesn't have full power. When I stopped on parking to check under the hub if actuator working, then my real problem started.

When I restarted car, actuator works well. Car start normal. When stick is N or P position, throttle goes up to 2000 rpm (no more then 2k rpm). Even then, it goes very slowly. When I move to D (drive position), throttle drop from 800 rpm to 600 rpm and car wont move !!! Same with R position. I tried to disconnect battery for couple minutes, nothing happened . I left car parked there.
Any ideas, what cause this !?! please

p.s. I apologize for my english, but I hope I succeed to describe my problem
