2011 n55 "engine malfunction! Rwdiced power"

Herakles · 01-29-2023, 01:50 PM

Hi all
Sk I have had a relatively drama free 7 year ownership with my 2011 335 xdrive msport which now has 85k miles.

This has happened before and basically just sent away- but starting to notice it more often; when I drive it with some motivation, some wot runs not always but lately the dreaded “engine malfunction! Reduced power” light comes on

I’m not sure where to start, I have a decent Indy shop bit wanted to reach out here if there is anything I can look into first

Thanks!

You are likely due for spark plugs and possible coil replacements, but first add a bottle of Techron to your gas. Follow the directions on the bottle. Add when your fuel tank is low on gas. Use the Techron in the black container.

Could be the HPFP, could be plugs, could be anything. You need to scan your car with INPA to know.
