2021 B58 Codes
I’m getting a chop idle on stock pump tune & e50 blend tune. Could it be my engine oil causing this ?
Factory recommends 0w20, but I was getting white smoke (not the pcv) from the exhaust so I switched it to 0w40 ? The white smoke was resolved, but 2 weeks later I switched it that’s when I have been having this problem (see attached image for codes). My guess is either I need a new TU HPFP or switch back to 0w20 engine oil. |
