Guys,
I've recently been updated and have noticed over this last week that the ECU never primes the LPFP the 1st time I open the door in the morning. This is really strange as the 1st cold start is the only time it actually needs to prime the LPFP! Consequently, my car starts no different to the way it did before the upgrade, ie, sometimes cranks and splutters, sometimes not. I've tried fooling it by energising the ignition, switching off, locking the door, starting the process again but it will not prime the LPFP until the 1st actual start is out of the way. Any one else noticed this? Cheers Yves |

What version were you running before? What's the throttle response like on the latest software, much lag? H |

My car is a mar 09 (never been updated) and has always run the lift pump, (often called LPFP) to prime the HPFP from the moment you press unlock on the fob.
My HPFP is on its way out now BTW, long cranks every morning. Some people on here have said the priming has been added in recent updates, but this must have been on pre Mar 08 cars as mine's done it from new. Strange yours is now NOT priming as this means it must have been removed now, have you had a new HPFP?? |

No idea what the version was before, it was loaded on in July 2009, thats all I can tell you.
No difference in throttle response from where I'm sitting, in fact the only thing discernably different is the LPFP noise while it primes itself. If it can be bothered that is! Yves |

Hi doughboy,
My car has never run the lift pump until this latest software update. No new fuel pump fitted although I am on my second one, the 1st having died Jan 09 so not a factor. Strange isnt it Yves |

I had the patch last month.
Prime begins when I hit the keyfob. Often Im working on the car without starting it, and it does it when I close it up too ![]() Steve |

Sorry Yves,
Your initial post said your car never ran the lift pump since the update... Quote:
Then you said the car has only run the lift pump since the update.... Quote:

Both things aere true.
The car never ran the lift pump before the software upgrade and now it only does it after the first start of the day which is totally useless. Come to think of it, it doesnt operate every time following the 1st time either... ![]() Coding error somewhere?? |

As I mentioned my car was booked in last week to have the latest software upgrade. My car prior to the update always primed the fuel pump but now I can't hear anything!! I've had my fair share of faults injectors / coils / actuators but no fuel pump issues. Needless to say the car doesn't start any differently, always withing a crank or 2. What I can report though is how well the car is running, very smooth and much much less turbo lag. My car had the actuators done back in April and I'm covinsed that they didn't instal the wastgate retrofit softare as it has been laggy ever since. However I can say for sure that this latest update has definatley addressed this as the car now responds very quickly. I also used to get an anoying vibration noise from the valve / flap in the exhaust at around 2rpm which has also disapeared!! |

Software is wierd isnt it.
My ECU decided to prime the LPFP once or twice last week on first start just to confuse me and with no discernable pattern regards outside temp, length of time left stood etc etc. Engine starts no different to before the update (actually worse if anything)and runs just fine when warm. Dont know what to make of it. Yves Quote:

Mines in this week for indicators (LEDs failed).
I've also mentioned the fuel pump / long cranking but as there are no fault codes raised by it (check on BT lead) they will probably do nothing about it. Probably update the software though as its still on its delivery version from March 2009. |

I suspect its looking at the feed pressure, perhaps it only leaks away over time. And some are worse than others.

Fyi - My local senior tech inform me that Progman no longer exists and has been replaced by Firmware which is used on the new ISYS (spelling) system.
Updates now take minutes. |

It's been ISTA-P rather than progman for a while now, but its just names.
My LPFP re-priming all the time, unlock, open a door 20 secs later, lock, unlock, open the bonnet, open the boot. Just keeps on priming..... It in today for HPFP investigation and a new rear light, they update the DME so we'll see whats changed when I get it back. |

Mmmm... would support my theory of worn pump guts leaking off pressure then?

map 0, then reset all the adaptations via BT (including the High pressure fuel adaptations) Immediately the car then started STRAIGHT AWAY. Next morning stone cold, it started ON THE BUTTON. The dealers have reported the same, I've had discussions about it with the the workshop manager and he took it home to check the starting at different temperatures and again no problems. He understands my concerns as I just want a new pump, but he says BMW have really tightened up on N54 fuel system problems, a year or so ago he said they would just throw pumps, injectors, coil packs and all sorts at it, but now they have to jump through hoops with test routines, including remote FASTA verification of diagnostics before they can get parts approved under warranty. They've carried out the full diagnostic routine, including splitting the High and Low pressure systems, checking both their running pressures, pressure rise rates and and residual decay pressures, and everything is 100% in spec. Now the car is on the FASTA remote diagnostic link where technicians remotely check it and can run additional routines. So, maybe its OK? Who knows? We'll see when I pick it up later. |

Got mine back from the dealers yesterday, Still starting on the button, they have done all the tests and said the HPFP is fine.
It has had the DME updated. Ta Da.... stone cold this morning - NO PRIMING - started on the button. 15 minutes later after refueling - IT PRIMED when I unlocked the door!! - Still started fine. Odd. |
