Hello,

Just had this pump replaced under the Recall a few months back, now today i get these codes...

Codes:
30FF: Turbocharger, charge-air pressure too low ( freaking car feels like i'm driving a scooter ) --???
After changing my hpfp 1st day so far, code hasnt come back, will report back if it does.

2FBC: Fuel pressure control valve. ??? *Confirmed HPFP needs to be Replaced. Replaced pump today, code is gone.

Here is a pic of the BT codes....

Should i take out JB4 anyway or just put it in MAP 0, i'm good with my SA but should i take it off anyway?

Thank you for ur inputs.

I know i posted about the code 2FBC before a few days ago, so I got an appointemnt tommorrow for it, but what is the 30FF code? Is it the same thing fuel pump related as well.?

Could be a boost leak or vacuum leak. Check all your vacuum lines, there is two that run behind the oil filter housing that leak frequently.

Boost leak is possible Check charge pipe and intercooler piping in addition to the suggestions in the above post.

Just had my HPFP Replaced today, and told my tech to check for any boost leaks, he said he couldnt find anything, but that 30FF code could also come up from the pump as well. So he changed the pump drove the car around for a good bit, rescanned it nothing showed everything works ok. I took the car from them and drove it home which is like 30-45min drive, and drove it in Map 0, suggested from my tech to not turn jb4 on for a day to let the pump adapt or what not, but like i said i drove it, went wot a few times nothing so far, everythings good.

Well see what happeneds within a few days and i'll report back.

Thank's for replys.

I bet its the other way around, but if it isn't please please please let us know.

Been searching for the 30FF code for months.

Sounds like a Boost leak.
