Question: For those people that feel that the dealers may be clearing codes and doing nothing, is there an aftermarket reader or scanner that will give the owner ALL the codes that BMW see in their shops?
Another idea is ask for a copy of the diagnosis report when you take your car in. I did that at my old deaolership and they gave me a copy. 12 pages of some very interesting stuff. A real page turner, "couldnt put it down" reading. I wont give away the ending, but the butlker did it in the library with the fuel pump.

I just got a call from my SA, my car is "done" and I asked about the part number. He gave out a number that ended in 933, (!?) and he explicitly mentioned this supercedes the one with the part number that ends in 943. More later. Quisp, get rhe BT tool - it's a must. This will be BMW's 6th part number to fix this problem. May God have pity on all of our souls.

The car is fixed according to the SA. They wanted to keep it overnight and do a cold start for a quality check in the morning. Again, more to follow... |

Car is back after receiving new fuel pump. All appears well. The car accelerates normally.
From my Invoice, the tech noted: "installed fuel gauge into system to determine actual fuel pressures. Initial Prime and residual pressures are within specifications at this time. Test drove vehicle with gauge attached and found pressure is insufficient under load. Determined high pressure fuel pump to be faulty. [diagcode: D1350_00000000_02_002] Removed and replaced high pressure fuel pump." So I recommend to all with HPFP failures that you ask your dealer to do this ["Test drove vehicle with gauge attached and found pressure is insufficient under load"], so you don't have to play charades like I did. The part number for this pump is 13-51-7-613-933. This supersedes 13-51-7-594-943 which in turn superseded 13-51-7-592-881. My SA told me this new HPFP has only been out 2 weeks. Also good information here by 1addict user "isitspringyet": http://www.1addicts.com/forums/showthread.php?t=377318 I had a sneaky suspicion this has to do with ethanol in our fuels. The law here on the front range of Colorado stipulates it must be 10% for smog reduction. For those of you who use lower ethanol in your fuel, I believe you will have a lower chance of having a failure. But this is not proved yet. Here's another link from wiki: http://en.wikipedia.org/wiki/Ethanol_fuel Last edited by IN54NITY; 05-20-2010 at 10:11 AM.. |

i wonder how much it would cost to replace the High Pressure Fuel Pump if you had to pay out of your own pocket?

i am getting about 2 second cranks at 840 miles. the car accelerates fine, but when i start the car cold, the brake is very difficult to depress and feels "locked."
anybody have any idea what this is?

Well, the past two mornings my 08 E93 did the long crank, irratic idle and the half engine signal along with engine malfunction in the idrive. I shut it off and restart and everything is normal. I have 33K on it now. I bought her used with 31K and when I bought her I was allowed to see the service history and the hpfp was replaced at 14.8K.
I'm just wondering if this "malfunction" gets stored in the pcm so a tech would be able to read it? |

Ok so maybe someone can help me understand what I was just told by my BMW SA...first of all, I dropped my car off at my dealer last night to have them check for / hopefully replace my 2nd HPFP as I've been having loong cranks upon cold starts every morning for the past few weeks and its been getting progressively worse. I never got any CEL's but I wasn't taking any chances again so I brought it in (about 10k miles after the first one went). Sure enough this afternoon I get a call saying that they did indeed find codes that led to a faulty fuel pump again once they were able to replicate the extended crank time. Here's where I'm a bit confused. The SA said that just recently BMW NA has been able to produce and provide a software update that can be loaded to our cars which allows for the HPFP symptoms to be eliminated without having to replace the pump again? (because I guess the pump itself may not be bad from last October or whenever I had it replaced)..He said that my car has been in the process of being reflashed and updated with the newest software for the past 5 hours! and that it was almost done and that it should fix the problem. I have never heard of such a thing before (let alone the nonsense of a 5 hour software flash update on a new BMW) and apparantly, if once its updated and they drive the car and find that the problem is gone and fuel pump codes arent being produced anymore, then my car is good to go. If they DO find faulty codes again, basically the 5 hour flash is a waste of time and they will replace the pump tomorrow. Does this make any sence to anyone or have any of you heard of this being done in place of just getting a new pump once the problem is found? Will this really fix the issue on the old pump and will my car be any different now with this so called "better" software update? Any feedback is appreciated. Thanks,
~Chris~ |

John 070 and TrackRat, thanks for the posts and info. To answer your question alloy: Yes. If a CEL (check engine light - 1/2 engine symbol) was thrown for your HPFP failure, a specific error "code" will be saved. Many different faults can be saved. It (or they) can be read at a later time by using a BT tool, a Proceed, etc. (I don't think your tech will be using the latter though. )

The other thing that is vague is I think codes are stored, and they are instructed to clear them and see if they come right back. If not, you're back on the road without a repair.... |

I've had 2 "updates" in the last 3 weeks. Experiencing LONG cranks, lots of lag and jerky transmission. Very frustrated and hopefully will get a replacement next time I take it in.

Yea, I too am getting Long cranks and a bit of transmission jerkiness as well AFTER having my first "update" last week.... I have a feeling this is going to be a long, annoying road of ownership. I hope I get a replacement as soon as I go back to the dealer.

Man, seems like a lot more 08's lately. Looks like they usually go out around 31-33K. I'm about to hit 33K. I just hope it doesn't happen while I'm in Europe. I know it will be a pain to get them to do it for free. If it does happen before I get back to the states...I'll probably just order the damn part myself and get a guy I know here to replace it. Or better yet, the problem actually gets solved 100% by the time mine goes out, yeah right...I could never be that lucky...
