Hi, I had 4 new coil packs fitted yesterday on my 04 bmw 318

This answer was rated:

Hi, I had 4 new coil packs fitted yesterday on my 04 bmw 318 saloon. Today I've had my engine cutting out when I'm slowing down. It doesn't happen every time but still frequent. No lights come on when engine cuts. I was wondering if this could be connected to the coil packs being fitted. Tried the garage but no reply as yet. It's never happened before.

This does not sound like something that would be caused by faulty coil packs, no.

I suppose it might be feasible, but what you have described really does not suggest coils to me.

Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.

Ok thanks. So would you have any idea what could be causing the problem?
Potentially a faulty idle valve, fuel pump or cam/crank sensor
