Hello and welcome! I'm Billy and I will assist you with your inquiry. I understand that having car problems can be frustrating so please feel free to ask if any further info is needed. If you get prompted for a premium service or a phone call, please ignore that, cause I don't think it is needed at this point. My apologies for the delay, thank you for your patience. May I know your first name?

Hello Annette,

This fault is caused by contamination within the fuel tank ventilation system, due to a defective fuel tank ventilation valve (TEV). So the first thing to do would be inspecting the fuel tank ventilation valve, and the inlet fuel tank breather line.

Ok, what would I be looking forOn those lines
BMW Mechanic: Billy, Trainer - MAster Tech. replied 1 month ago

First the valve itself, make sure it's not clogged, and the lines should be clear.

Ok

After doing so, and if the valve needs replacing (it most likely will) make sure you update the engine control unit software.

Can I still drive my vehicle with this issue only have this carI don't dare turn on my AC
BMW Mechanic: Billy, Trainer - MAster Tech. replied 1 month ago

Yes, this fault should not cause you any problems. You can drive the vehicle. And the A/C is not related. It's just a coincidence, so you can use it as needed.
