In this video, I will discuss a problem with our E46 325Ci where the engine will surge at idle just after starting usually just after fueling but always during a hot start. We will diagnose the CEL code P1447 (Diagnostic Module Tank Leakage (DM-TL) pump current too high during switching solenoid test).
