Weird Boost Issue

RLNY · 02-16-2024, 08:40 AM

Weird turbo issue on my x5m . So i got the 30FF and 310b codes today. They did pop up a few days ago after a hard launch but erased and didnt come back. However today i cleared them and they would come back only after shutting off car and turning back on. I monitor boost with bimmerlink and for some reason it shows 0.99bar at idle. That cant be right? When at full boost after i erase codes and engine malfunction message it boost to 1.24 bar. Could this be a leak near my wastegate or and issue with wastegates.

Sorry i Write in Germany.

Ich habe diese Fehler auf dem Prüfstand bekommen. Ladedruck zu niedrig und unplausibel.

Wie immer die unterdruckschlauche pruefen , die pneumatischen Ventile und zum Schluss mal per Endoskop schauen was die wastegates machen.

Vielleicht hat jemand hier noch Tip, welche Seite mit 310b gemeint ist.
