Hi guys. Still got one problem om my MB. This is facelift model with 7G gearbox. Tryed everything… already changed intake manifold(was cracked), restored both turbos, replaced fuel pressure regulator. Injectors tested - ok. What else can be?
Manifold new, without swirl flaps, but motor still in place. Sometimes showing fault of that motor (incorect signal), but I dont believe what can give any simptoms (same problem was and before manifold replacment). I will delete it. EGR blocked and already deleted.
Car jerks from 1400rpm to 1900rpm on soft acceleration. Torque converter restored. Thinking, can be cluth solenoid…but no other fauls from engine ir gearbox.
And it’s so annoying…
