So I just changed my DP's top the Fabspeed High flow DP's and after about 50miles I had the CEL light come on. The codes were for 'fuel vent valve malfunction'.
I know there was a software update for this and apparently my car has the latest software, so it is not related to software as per BMW service.
They are charging me 1300$ to change both the valves.
Has anyone experienced this or has any input on this.
Car is 2018 M5 with 30,000 miles.
Thanks
Jake

There was a kink in the fuel vent valve piping that caused the issue. Replaced the piping and all is good. Around 110$ part
