P120D P00BD After Hitting Top Speed

yacob555 · 06-08-2022, 12:10 AM

Topped the car out on a very nice open safe road, the fuel shut off but then I got these two error codes right after. They come back after the codes have been cleared.

Any idea what happened / how to fix?

I’d try cleaning the MAF sensor. It’s two small hex screws to take off and is on the air intake hose after the air filter housing. Use isopropyl alcohol or MAF cleaner spray. Be careful with it as it has fine wires that can be easily damaged, so no brushing it off.
