Hello everyone.

So recently bought this M5 and I have EML light coming on with code:
118011 Mixture control, Across bank mixture too Rich.

Car seems to drive fine no misfires, might be a little low on power but not sure as haven't driven any other ones.

have done the following recently trying to fix it.
New spark plugs, new air filters, new pcv vent hoses. Did a smoke test but didn't find any leaks in intake system.

Also it's kinda high mileage 120k miles.

If anyone could help would help would highly appreciate it.
