Codes arent showing up again, but getting a rough idle now...
I'd get that checked for sure. Also maybe clan the Air MAF Sensor. Easy start.

Any suggested thread to look at for instructions.

Eisenmann Race Full Exhaust System with Oval Tips
Fabworx catless downpipes
DME stage 2 tune & new spark plugs
Project gamma cold air intake

Problem is it legitimately smells like a go-kart you'd find at the amusement park...aka it stinks like gasoline and seemingly is running rich.

No CEL is on, but has the following two codes thru Carly:

20E121 - Crankshaft Ventilation 2
140011 - Misfiring: injection cut

Ive done searches but none allude to anything causing such a gaseous smells coming from the exhaust system.

Any ideas, solutions?
Good luck to you you had some big balls buying an M5 that was already modified I would never have the balls to do it
Mine's modified all to hell lol but I did it all

To each their own but should be all fine, most of the mods were re-done and checked in a thoughtful PPI and by DME before purchase.

Also changing out some of the mods are being changed as we speak.
