Hi all,

hoping someone can help! I have a 2014 2.2 Diesel. I have very low power until what I assume is the larger turbo coming in at around 2.5k revs. I have no codes, already had all the intake manifold and EGR etc cleaned out and the problem persists.

it used to happen intermittently but I had P2262 codes back then. I cleared it and it would run fine again for ages.

Please can anyone help… I don’t want to keep throwing money at it and getting no where!!

 

Check the wastegate, these bi-turbos are known for the smaller/primary wastegate flap rivet to fail and the wastegate stays open, loosing boost.

 

Thanks for the response.

can this be checked while on the car or only removed?

 

You can remove the intake pipe and inspect inplace.

 

is that not the larger turbo?
