Got a T2 v6 TDI that maybe one or twice a month comes with a overboost fault. When it comes on, sometimes its just a cruising and not under load. Checked all the hoses/lines, nothing seems damaged or leaking. Checked the MAP sensor and the pressure sensor, No concerns there. Visually seems okay. I performed a output test on the control module of the turbo and it seems to be moving properly. Doesnt seem jammed. Now this is very sporadic cause I've driven the car very hard and it never happens. Its very random when it happens cause it could be a cruising speed or maybe some hard pedaling. Heres screenshots of the fault and the open/close of the output test.
Car is tuned with Malone with a delete. Im suspecting maybe a sticking actuator when it comes on. Maybe just every so often. Not 100% sure though. Hoping someone has some idea.
Thanks!
