    Unhappy VW Crafter Causing Months of Frustration........



    Hi all, thanks for letting me be here.

    We have a 2007, 57 plate VW Crafter. It has literally caused us months and months of frustration not to mention the money we have thrown at it.

    We initially had a problem with it going into limp mode every time we drove it. We have researched for months and and months and have done the following things to the Crafter:

    1) We took off the turbo and cleaned it thoroughly.
    2) We replaced the turbo to have the same problems.
    3) It was put on a diagnostic machine which came up with EGR fault, that was replaced with a brand new EGR which actually made it worse making the Crafter instantly go into limp mode every time it was started.
    4) Diagnostics were used again and it still still said EGR fault.
    5) We had someone out to re-program the ECU and by-pass the DPF (we had previsouly drilled a hole through the DPF) but this hasn't worked either.

    We now have the code P0299 saying Boost Pressure Control Below Control Limit and it's still going into limp mode but not as bad. Limp mode now comes in at around 65MPH every time it's driven. If you get the revs up through the gears, it's ok but as soon as it hits 65MPH it happens again.

    We are at a total loss of what to do next. The turbo is fine and has been checked thoroughly. The vains are perfect and moving freely. We just don't know where to go next, we're at our wits end with the thing and feel like scrapping it.

    Any thoughts would be so massively appreciated, I am literally in tears writing this today. We have lost so much business because of this vehicle. We have a fantastic mechanic who has helped us so much ( my husband does mechanics too so we've been able to save on labour charges). But now, we're stumped xx

    Limp mode: What is it, what are the causes, and how to fix it for the Audi and VW TDI diesel turbo

    VAG Error Code: 16683
    EOBD II Error Code: P0299

    Fault Location:
    Boost Pressure Regulation - Control Range Not Reached/Low Boost

    Possible Cause:
    Malfunction Indicator Lamp (MIL)(K83) active.
    Reduced Power Output.
    Limp Mode.

    Hoses/Pipes incorrectly connected, disconnected or leaking.
    Charger Pressure Control defective.
    Turbocharger (TC) faulty.
    Diverter Valve faulty.

    Possible Solutions:
    Check Hoses/Pipes to/between Components.
    Check/Clean/Replace Charge Pressure Control.
    Check Turbocharger (TC).
    Check Diverter Valve.

    Special Notes:
    When found in 2.0l TFSI:
    Check Boost Pressure Control Valve (N249), for cracked rubber diaphragm. A new/optimized Valve is available under Part # 06H-145-710-D (or newer).
    Rest of World (RoW) vehicles see: Technical Product Information (TPI) 2016331 for details.
    North American Region (NAR) vehicles see: Technical Service Bulletin (TSB) 01-07-70 or 2013392 for details.
    When stored in conjunction with misfire codes and/or fuel trim faults see the notes associated with the following faults regarding Positive Crankcase Ventilation (PCV) failure: Crankcase Breather Valve
    If the Turbocharger is faulty due to mechanical/internal problems or the exhaust system is restricted (typically the Catalyst) this fault may be the end result.
    When found in VW Golf/Jetta (1K): 2.0l CR-TDI (CBEA/CJAA):
    Verify the mechanical part of the Exhaust Pressure Control Valve (J883) is not seized or binding.
    When found in Audi A4/S4/RS4/Cabriolet (8K): 2.0l (CAEB):
    See Technical Product Information (TPI) 2031245/6 - turbocharger excessive waste-gate play.

    All checked and appear to be working. Just looking into an N75 Valve that we hadn't heard of before. Thanks for your post

    Check that the vacuum control system is air tight by applying a vacuum to the source connection, it should not be possible to continuously draw air through this, leaks can generate the low boost code.

    Vile Invention

    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.

    Hi, thanks so much for your reply.

    We have the N75 Valve now...Hubby is fitting it now and taking the van out. Have told him what you said and he will be checking that as well.

    I recently had a similar P0299 fault , sometimes with P2bac as well.
    Pressure tested induction system with compressed air to 20 psi -ok-
    Did realtime roadtest scan with ELM 327 bluetooth scanner and found boost rolling off towards 75-80 kmph. checked how wastegate is actuated. blocked off hose at vacuum control valve (N75) and fixed fault.
    Fitted new valve and test drove and came up twice , early in drive with P2bac, cleared them ok, then ran without fault at up to 120kmph in 6th gear.
    --Then celebrated with much liquid refreshment-- (its been an ongoing issue and a love job)

    Thanks from sunny Northern Territory, Australia

    First posts normally go in introductions else you could get a free fix and we never see you again!!!

    That's not a proper scanner you need VAG-COM\VCDS.

    That's an only post I posted in there are a few updates on the new version.

    Many apologies Keith,its my first foray into forums and not looking for a fix ... ( already fixed it)just sharing the knowledge to help others. The initial scans were done with a Ross Tech VAG COM VCDS but it was a bit hard to do a live test with laptop on my knee whereas,with the bluetooth I could read straight from the smartphone on dash and reset fault while driving. Cheers from the frontiers.
    Ten hours ahead,ten years behind.
    AND we like it that way!

    Don't apologise CB it's just some odd forum protocol here.

    By the very nature of all car forums is an initial fault finding diagnosis for many .

    If these posts get started or end up in the introductions people ( hundreds of lurkers ) with similar issues would never think of looking in introductions for their particular vehicle .

    Poor old Keith if he doesn't change his ways and 'let it go' like Elsa , he'll be saying ,

    " First posts normally go in introductions else you could get a free fix and we never see you again!!! "

    For the rest of his life !
