Code 235 / P1092

FPR and fuel filter one in the same. (Well technically they are different but on e53 they are in the same assembly).

@tn52: are you running rich or lean? My car has been running lean for a while. I get a good long reprieve if I reset adaptations but the fuel trims are showing a story as well as the post cat O2 sensors. I'm getting too much air or too little fuel.

Low fuel pressure or vacuum leak or bad MAF are the main reasons, clogged injectors or crappy quality O2 sensors next on the list.

I'm going to do an explosive vapor intake test (where you pump propane or starting fluid etc. near intake parts and watch the real time fuel trims. Get a rich spike you found the vacuum leak)
