I’ve recently noticed a burning smell coming from the front of my XC90, upon visual inspection I don’t see anything. There occasionally has been some white smoke while driving seeming to be generated from the driver’s side firewall.

Two most recent codes to pop-up were P2421 (evaporated stuck open) and P0193 (fuel rail pressure sensor circuit high).

Thank you in advance!
