Engine Performance problem
2003 BMW 525 6 cyl Two Wheel Drive Automatic 65000 miles
First noticed occasional clouds blue smoke from Exhaust. Then - after 3-4 days - EML light come on, loss of power and obvious misfire. Diagnostic codes P0300, P1345 - misfire Cyl 2 with fuel cut-off? And P1349 - misfire Cyl 4 with fuel cut off? Recorded.
What is probable cause? With engine running, as each coil lifted out in turn, little change in engine note (so mechanic thought probably not coils!). Thought all petrol not being burnt fully. Smoke not continual. No previous engine trouble. Car is a UK, Sport model.
