Hi, I’ve got a 2010 BMW 1-Series 118 m sport that has done 53000 miles. The engine light started flashing a couple of days ago so I took it in and it was a misfire as one coil was failing (as we thought). We had all coils and spark plugs replaced yesterday as I had read it is better to get them changed at the same time. It ran fine yesterday, then this morning when I turned it on first thing and started driving the engine light started flashing again. So I pulled over, stopped and restarted and it ran fine with no engine light. What could be causing this? Could it be it just hasn’t reset or maybe a cold engine? Obviously I will take it to the garage on Monday again to see what they think but just after some suggestions.
Thanks in advance.
