Hello everyone, im new at forums so please bare with me. I have a CLS320 D 2006 (w219) and it was bucking. After some research we changed the back pressure sensor and then my mechanic came down to the conclusion that the turbo needs replacing and so we did. After replacing the turbo complete with the actuator the car now started bucking again. Not at the level it did before but the problem still persists. I read a thread that the manifolds might be cracked. The codes it comes up with are in the attached picture. I desperately need help. Thanks in advance guys.
