Your file is nearly a perfect match with the 4B0906018CH.
Do you have complete official definition for this file?

boost problem solved - it was vacuum hose that controls turbo. now another problem showed up. i get super weird o2 correction... as if im running super rich but if i disable front o2 correction my car drives as it should. with front sensor enabled it feels like it runs really lean especially during boost...

i dont know of any vacuum hoses that control the turbo :/

also, you are going to need to log a few more O2 variables if you want to diagnose O2 issues.

have you tried swapping O2s?

I'm sorry that I wasn't clear about that vacuum hose. It is the hose that goes to wastegate actuator...

Could you share info on what other variables should I log? Everything that goes out of *LRS modules? Also I don't have a spare o2 to test (single bank car)

Unfortunately, I am not familiar with that ecu ... but certainly o2 voltage is a start Smiley
