E39 540i Eng Failsafe Prog, you know the drill
Long story short, about 2 months ago I accidentally sucked up some water in my intake, hit the MAF and triggered eng failsafe, exactly how it should work. Unfortunately, that water broke my MAF. Diagnosed by:
Starting car, had failsafe
Start car, no failsafe but idles bad
Plug in maf
So, I get a new MAF, Delphi I think? And put it in. Runs perfect for 2 months and like 1000 miles, and suddenly same thing, and previous diagnosis still works. I'm getting a replacement MAF tomorow but I'm wondering if something else might have caused this?
