    So this has been quite a long standing problem I have had on my 3.0TDI, but it has recently become undrivable! When under load (used to be full throttle now it is most of the time) I get a flashing coil light. If I do a scan, the fault I get is “Fuel Pressure Regulation Control limit exceeded Upper limit exceeded”. I have already replaced the high fuel pressure sensor on the LH rail and the high fuel pressure regulator on the RH rail.

    I know there is a flow metering valve on the back of the HPFP, so this is going to be my next target as it is the only thing left that hasn’t been replaced. This is getting expensive though, so wondered if anyone has seen a similar fault and how they fixed it?

    I have attached a scan below, and will try and make a data log when it happens.

    Not got a new one yet, I have been away. I managed to pull the HPFP out on Monday as you have to remove it to get to the valve (much to my dismay as I had just put all the bumper back on, and to get the HPFP out it all has to come off to the service position)

    I’m going to give it a good clean out and test tomorrow. If not it appears to be about £100 for a replacement.

    I assume you have similar symptoms then, not a solution?

    Did you have to do adaptions after replacing it or was it just plug and play?

    So I have sent this to a diesel injection specialist, their diagnosis, after also speaking to Bosch technical I s either the HPFP Fuel Intake Metering valve, which can be bought for about £100 or a software problem.

    I will update once I have replaced the valve, it has just come in today!

    For anyone with this fault, replacing the metering valve on the back of the HPFP fixed it for me, now works flawlessly!

    They aren’t available for the A4 from Audi, however a VW crafter uses the same valve and they will sell it to you for ~£100.

    Audi/VW part #: 059 906 457
    Bosch part #: 0928400676

    Very useful information, did you use the part numbers off of the old one to do this? 059 906 457 is £204.73 genuine so did you use one from Bosch?
    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.

    Internet research gave me this information, as Audi’s only advice was a whole HPFP! I just started searching for the part number that was printed on the valve.

    I ordered one through a company called Thames Valley Electro Diesels. eBay has many new ones listed though. Genuine Bosch units.
