Bad Fuel pump again? Did a BT scan and found this...

ace008 · 07-23-2009, 09:51 PM

These past few days, I've been getting long cranks and rough idle startups when the car is cold. A couple times, the Engine Malfunction light came on and SES light. I got my BT tool and it found this:

Sounds like a bad fuel pump... This is the second pump I've gotten. Any ideas on what else they need to replace? Spark plugs, coils and injectors?

Darth335 · 07-23-2009, 10:54 PM

Looks like a fuel pump again for sure. I have read about guys on their 3rd pump, and even cars that have gone back to BMW due to the lemon law for the file pump. Hopefully you do not have too many mods, but take off what your can (tune, dps, etc.) and take it back to the dealer and have them check it out.

scalbert · 07-24-2009, 08:20 PM

Looks HPFP related, easy nowadays. Heck, like some, considering keeing a spare here just to avoid taking it to the shop.

ace008 · 07-25-2009, 02:26 AM

Brought it into the dealer. They are replacing the HPFP, all 6 injectors and updating the software. Getting the car back Monday, so we'll see what happens.

TurboSid · 07-26-2009, 08:12 AM

How long has it been since u replaced the pump last time?

jlangton · 07-26-2009, 12:27 PM

Seems like mine may be on the way out too; just coming up on 2,400 miles on the car

I had code "2FBF Fuel pressure at injection release" trigger along with the SES light, and have had occassional long cranks.

Glowin · 07-27-2009, 05:59 PM

Ace, (or anyone else)

I assume the 3 codes regarding the misfires led them to replacing the injectors?

Do injectors go bad directly as a result of the pump, or are they unrelated and just a coincidence in this case?

I had the codes 29DC, 29F2 and 2FBF which are all pump related I believe, but not any misfires, and they've decided to replace the pump only.

ace008 · 07-27-2009, 09:06 PM

Got the car back today. They ended up replacing all 6 injectors and the HPFP. They also performed a software update to 2.34.2.

Mods - JB3 1.3, BMS DCI, RR 2nd Cat Delete, Bastuck Exhaust, Koni FSDs, and H&R Sways.

On the report, it said misfire faults: 29CE, 29CF, 29D0, and 29DC. Faults 29F2, 2FBF stored for High Pressure Fuel system.

Maybe the misfires indicate the injectors are bad and the 29F2, 2FBF are HPFP?

s1cke92 · 07-28-2009, 04:35 PM

ace008 u took in your car with all those mods?

Yes please let us know what mods you went in with. If I should have this problem in the future and they deny the HPFP DUE TO MODS i WILL POINT THIS OUT. THANKS

LOL! Are you serious? You're going to print out this thread and go and show them as proof they should not deny you warranty work?

LOL I don't think thats going to work...

Glowin · 07-28-2009, 07:00 PM

Ace, what was the part number for the pump? Was it 13517592881?

I wonder if that's the latest version one?

Yeah thats the same one I got. So far, no more issues... for now.

gt3fever · 07-29-2009, 04:37 AM

ACE, did you get the software update while they replaced the pump ?

Mine is sitting at the shop for the HPFP also, and wondering have they updated my software...

Yeah, they updated my car to 2.34.2. Car feels much better. No more turbo lag and a lot more responsive below 3000 rpms. And this is before a tune. I wonder what it will feel like with the JB3 back on. I think I had 29.2 before.
