Anyone ever experience engine or exhaust fumes inside the car? Nothing obvious but before I dig into mine I want to see .
thanks

Not on the F10 but my 1994 E36 M3 at one stage had petrol fumes coming in from the dashboard air vents. It turned out to be, after I traced all the fuel lines and connections, a loose rubber hose connector on the in-coming fuel rail at the back of the engine. After re-tightening the hose clip the smells went away and have never returned.

Not with my F10 but in my old E92 it was valve cover gasket leaking to exhaust manifold and burning off causing a bad smell in cabin.

Thanks guys. I'll dig in to it, it's an 11' something isn't sealed right.

Try turning your air you recirculate to see if it's coming from engine bay.

Oil or gas? If oil maybe look for leaks around from the filter housing or valve cover gasket. If gas, check out the HPFP, fuel lines and injectors.

I'm getting exhaust fumes mostly.
Before I cleaned the valley I was getting burnt oil smell
I've done everything inuding fresh air or recirculation except tearing into the heater box and firewall looking for a obvious or something not sealed anymore

I had the same issue and just replaced my crankcase breather/vent hoses on both sides and the smell is gone. One was completely broken in half and the other had cracks. P/N 11158645239 & 11158645237.
