Hello Everyone,
It is nice to have joined this community. I am new to diagnosing my 2008 Mark V, R32 with a turbo/aftermarket tune. The problem all started with the ambient air temperature sensor faulting. It has since been replace. The car was driven in what I understand as limp mode, which caused the car to run rich and the car would not move an RPM above 5500. There was puffs of black smoke during shifts.
So I was advised to data collect on blocks 001, 020, & 021 for my tuner to diagnose. Right now, my tuner is unavailable for the next several weeks and I was hoping to gain some insight on 1) how to interpret the data presented below. 2) Given the explanation above... with the data below, does anything jump out at you?
There is was no fault codes in the engine module during last scan (about 30 miles ago).
The aftermarket turbo will barely get to 10 psi of boost. Before it would snap to 17.5 – 22 all day long with little to no lag. I have checked the boost track and nothing is leaking. The other thing I suspect is maybe the CATS are clogged up from running the car in limp mode more aggressively than I perhaps should have done. Please advise.
