Hi
My dad has a 2008 535xi. A while back the engine started to run really rough and threw a code. I read them out - it was a misfire on cylinder 5. The car had spark plugs done fairly recently (about 20k miles ago), so I decided to change out that ignition coil. Replaced it, tested it, and all seemed to be well
Fast forward to now (maybe 3000 miles later). Car again threw a code and suffered a severe loss of power. Pulled the codes, and again, it's a misfire on cylinder 5.
Given that the spark plugs are pretty new and the ignition coil was very recently replaced, I'm inclined to think that the issue is something else. Is there anything common on these cars known to cause intermittent misfires?
Car has approximately 70k miles on it today. Runs well otherwise.
Appreciate any help you guys can provide.
