2a9a 2a9b Help

Hi I been having vanos issue for very long and replaced almost everything vanos related on my 335ix and I wanted ur opinions on a bad crankshaft sprocket on the hub causing these codes, I put it a new timing chain but didn’t bother replacing the sprocket, any help would be nice

Quite possible that the timing is out. Verify that your timing is spot on.

Everytime I do set it it runs for a little bit than I get vanos codes then so would get 2a9a and 2a9b stall and won’t start no more
