I did a vcds log and I saw my car is overboosting.
Max requested boost is 1.6 bar in a wide rpm range, but it shoots up to 1.89 bar.
Redline boost is ok.
After shifting it rises again to 1.9+ bar, than it drops again at redline.
Requested lambda is 0.849 most of the time, but I have some fluctuations here too.
On WOT at 3000 rpm it goes down 0.82 than rises even to 0.867, than it drops to 0.83 at redline.
I had P0131 code in the past.
Timing pull is not that bad, it's up to -3 at higher speeds on cylinder 2 and 3.
WG actuator voltage is 3.628v when ignition on.
Where do I start from here and is it a problem with the car?
Thank you
