Fault codes help!

HermanL · 03-15-2014, 11:28 AM

Car have been feeling very sluggish so I decided to pull the fault codes this morning and boom!

2AAF
30FF
29F3
2FCA
2FDA
2E9F

I have been having 2aaf and 30ff, replaced all the vacuum lines, charge pipe DV, still cant figure out what is wrong, been wanting to do a leak test but never got around to do it.

Some wastegate rattle with catless downpipe, tried to get them replaced by warranty but dealer denied it since it is barely audible with stock cat on.

I searched and though both 2FCA and 2FDA are HPFP related, does it mean my HPFP is dying?

I am not sure what/why 2E9F is present

I am currently running cobb stg2+, will return to stock and if see codes come back, at the meantime, anyone want to share their thought on what to look for next? thank you for any input

I don't have my definitions list. Can you post the code descriptors. Quick google search identifies the HPFP codes and 2E9F is oil quality sensor?. When was your last oil change is the level good?

Thank you for your reply, I do not have my list either, as far as I remember, 30ff is boost leak code, I have no idea why I would have 2E9F, last oil change was about 4000 miles ago, oil level is half way between max and min as indicated

Ok this is what I got. You'll need to log for most of them. Remeber to reset to default cobb pids for the log.

2AAF fuel pump plausibility. (Need to log to see low pressure fuel.)
30FF Boost under target (Need to log wgdc etc)
29F3 fuel pressure sensor Low pressure (need to log)
2FCA HPFP?
2FDA Crank case vent issue.( also resulting in 2e9f issue probably)
2E9F Try what OP did in this thread (Click here)
