CEL: Error Code FF1946

DATN26Shheeesh · 03-03-2022, 11:58 AM

Hi folks, I got a CEL and ran the Bimmerlink App to check for error codes.

FF1946 - No further information
194501 Tank Leakage module, communication/ Malfunction
194604 - Tank leakage module: electrical open circuit
194602 Tank leakage module, electrical short circuit to ground

The car drives normal, the FF1946 error code is the one that most likely caused the CEL. I also tried: https://bmwfault.codes/ but came back with nothing

Wondering if anyone has come across FF1946 or any of the 194... codes.

Mine had this error, it turned out to be wiring chewed by a mouse.
