Dear all, the above car a number of weeks ago went into limp after one or two hard acceleration pulls, codes read by my indie and the MAF and blocked secondary cat were to blame. These have been changed for new parts and the pre cat, after the turbo was gutted.
Car accelerates very hard now (I suspect an overboast) but still goes into limp after 1 to 2 hard acceleration scenarios, EML displayed, fault codes read (Charge Pressure to High and Charge Pressure to Low) I suspect a poss sticking turbo actuator.
Now this is my question.... can the turbo waste gate actuator on this model be changed separately from the turbo or does the whole turbo unit with actuator need to be changed? I am sure I have read somewhere that each actuator is calibrated to the turbo its fitted to and you cant just purchase a new actuator and fit it to the turbo?
Apologies for the waffle, just wanted to give rough summary of history before asking my question.
Kind Regards
Matthew
