i changed a ton of crap for mine (see older posts) but would recommend taking it to the dealer and starting with the cheapest and going up.. rail sensor then fuel pumps. not sure if mine was a more extreme case but from what i've seen a lot of times these should work.

since i had the gas tank replaced, i did have 1 reoccurence but it cleared when i got gas and never came back so far. by any chance do you run your tank nearly empty a lot? i used to almost always run mine past E and lately i've been filling up before the light even comes on. i'm not sure if the issue was this or maybe a combination of everything but I haven't had any issues recently.

hope this helps.

Got this code 3-4 month ago for the first time, cleared it the first time. 2 weeks ago it popped up again looked at the fuel pressure at idle at it was 0.1-0.15 bar higher than the set value. My question is, which of the pumps did you guys change? Main or auxiliary? I don't think changing the pressure sensor at the rail will do any good. Any ideas or thoughts ?
