Hey guys,
Anyone know why a B4 will limit boost to about 0.5 bar? Valley of death is still there, boost drops to 0.3 and secondary turbo boosts back to about 0.5 bar.
I parked the car, turned it off and its boosting normal again. It seems like the ecu is limiting boost for some reason? But why does an engine restart fix it?
It happened once a month ago and occured again this morning. Other than that, the car drives fine. I havent done anything unusual. Petrol is 98 Ron 1/4 tank atm. All engines fluids are good. No CELs. Car is stock apart from a hurricane? cat back.
Apparently the previous owner replaced the o2 sensor already last year.
Cheers guys.
