Hello guys. Got my first used 07 X5 and drove it for a few hundred miles and got a 420 and 430 code. It did not have any ill effects until 150 miles after that. It then lost power and now has rough idle and is barely drivable (which i am not) . It then threw 301 and 302 codes.
The obd fusion report is
Diagnostic Report 2020-08-09.pdf.
I installed all new plugs and I swapped all coils and the code remained the same. The rpm does kick down when unplugging each coil. The electrical plugs are pushed on coils tight as well. Im almost positive it cant be the plugs or coils. I did search first and thanks for the help!
*I just got back from the dealership(not BMW) that sold it to me. They claim it needs an ignition coil and spark plug in cylinder one. Like stated above I changed plugs and leap frogged all the coils already. (#1 coil is in #5 now. still showing #1 misfire.) They want $325. to fix it lol. They also said I have a hole in my muffler.
