My '08 R56 is giving me fits. It starts in the morning, runs for 5 - 10 minutes then quits. It will not restart. A few hours later or the next morning the same. The only DTC showing is P0303, but that DTC has been intermittent for many miles prior to this issue. I have replaced the DME, HPFP, fuel filter, fuel pressure regulator, fuel pump, crankshaft and camshaft position sensor, and thermostat to get rid of other codes. When it quits it does not sputter or stutter, it just stops running.
Can anyone give me some guidance? Last edited by clint21anne; 09-30-2023 at 04:17 AM.. Reason: Added more information |

In case anyone is curious, I found and fixed my problem. The wire harness to the crankshaft position sensor had been crushed when I installed the new knock sensor. I know I was not careful enough, but in my defense I was laying on my back with the bottom of the vehicle only inches away from my nose. Not much room, but still I shouldn't have made such a mistake. Anyway, after repairing the wires the stop running issue was fixed.
Thank all of you that offered suggestions. |
