Already replaced Vent Valve - BMW (13-90-7-636-145) and gas cap. What else could be throwing the code? Thanks |

heyo! Had the same issue a little bit ago. I replaced the vent valve located on top of the engine…
What i've found from my research is that it could also be a vacuum leak in the fuel system. An indie shop should be able to help out by using smoke and pumping it into the system. They let it sit for a little (for the car to do another vacuum test once turned on) then look at all the areas for visible smoke… this shows them where there could be a hole in the system which causes a vacuum leak. I am sure you did, but when you replaced the vent valve, did you reset the CEL? |
Appreciate
