1 Φεβ 2022 · So we all know that 28A0 is a vacuum leak somewhere. I had codes 2BEA and 28A0. Changed the valve cover with a cheap-o aftermarket and BMW OE gasket. It fixed my code 2BEA (Mixture Control Too Lean), but didn't fix the 28A0 code. Replaced crankshaft seal and no more 28A0 (after adaptations), but received code P112F.
Most of the research I did seemed to indicate issues with a tune, but my car is entirely stock. Finally, after two attempts to find a cause, a leak was found in the charge pipe and it was replaced, the throttle body cleaned, adaptations reset, and the codes were cleared.

7 Δεκ 2020 · No major problems to date. I've been changing the oil every 5,000 miles and getting caught up on routine maintenance items. Last week CEL came on and scanned 28A0 - throttle angle - absolute pressure suction, comparison pressure too high. The car is basically symptom free.
