Hi guys, I don’t post much, bit of a lurker. But I thought I’d reach out to see if someone might be able to help me with my friends bi-turbo amarok (I forget what year it is but will update when I’m closer to the vehicle) that keeps going into limp mode and throwing P02CB turbo underboost condition code. I’m a mechanic so he bought it to me after losing faith in the previous workshop. I don’t have a lot of experience with these cars but I said I’d do my best.
The previous shop has replaced the two boost control solenoids, removed turbos and inspected them for wear and checked wastegate actuators, leak tested intercooler plumbing, checked the dpf and exhaust for excessive back pressure and tested the harness for open circuits etc...
All of the above seems pretty logical, so I have started by inspecting the egr and ecu connectors but everything looks very clean and well looked after. My scan tool isn’t showing live data very well so I’m struggling to monitor map sensors and alike.
So I did some googleing and not coming up with a lot of information. Any advice or experiences would be appreciated
Cheers J
