Started this morning. Cut out momentarily while driving .....
2003 320i M54 2.3L SE Coupe. Doing 30mph in 4th behind a bus. Suddenly engine dies and recovers immediately. Stopped at lights. Idle fine. Started off again no problem. Pulled over at first opportunity to check codes. No codes. Spent the day in work. Coming home tonight same thing at about 35mph only more abrupt. The only difference is that this time the DSC, ADB and DBC lights came on and stayed on. This isn't a problem. All it means is that whatever happened turned the The Dynamic Stability Control, Automatic Differential Brake and Dynamic Brake Control (DBC) off and they stayed off. I can do that by pressing the button for 3 seconds. After that no problem with running or idling. Got home ok. Checked the codes and had a P0335 Crankshaft Position Sensor fault. So I guess I will be changing that on Saturday, if not before. Just thought I would run it by everyone for an opinion. Do the symptoms sound right for this fault? The thing is, I had both cam sensors and the crankshaft sensor replaced in June on a just-in-case basis. Could it really have packed up so soon?
