    Guys

    Just been reading as much as i can on this thread and im seriously worried about my avant. I have a 2006 2.0Tdi 140 (BLB) and since i have owned it the car seems to pulsate/surge on normal driving. Being lazy also i havent been checking my oil level due to it only being serviced 5 thou ago and it doesnt have any leaks, but my oil level light came on the other night, so just topped it up and have been checking since.

    Ran VCDS and got one fault


    1 Fault Found:
    005731 - Control Circuit for PD Injectors
    P1663 - 000 - Short to Plus - Intermittent
    Freeze Frame:

    Can anyone advise me what to do please, im hoping i have caught what ever it is early.

    Thanks

    Thanks for this Paul, but as mine hasn't gone yet, what are my options? Go to Audi or get rid?

    Newbos,

    "You pays your money and you takes your pick"
    I had saved for the day and had Audi do the conversion for me , others have taken other paths.
    Good luck with whatever you decide to do .

    cheers for that, interesting to have small plastic parts doing such an important job while covered in hot oil

    I believe others have tried to do a straight swap and it doesn't work !
    As a minimum one would need to swap engine, DIS and ecu and possibly the manifolds.
    I am almost sure others have tried and failed so lest hope someone who had tried to do this or even has managed to do it will jump in and advise ?

    So far as I am aware, noone has successfully swapped a BLB for another engine code. Part of your problem will be in the ECU I'm guessing.

    so im doomed to put back a BLB but mod it with new oil pump drive, i thought the 2.0tdi engine was the same unit as long as it was perfixed with a B and the the other letters LB or RD,or RE and so on were mods on the same basic block like the oil pump drives gear driven on the RE

    bugger back to the drawing board

    Hi All

    New to this but wanted to share my story/get opinions on the best way forward. I have a late 06 avant 2.0 tdi which I purchased just inside the warranty. I had a balance shaft modification done by my local Audi Dealership as it was outstanding. This was just over three years and 50k miles ago. I had read about the pump issue, but little was documented upon it then. Having the car has been great apart from the odd little thing, but it has now done 135k so you have to expect this.... But this week it all went wrong, the Oil pressure light came on, I stopped quite quickly and got towed home where the car is sitting sadly. I have not asked anyone to take the sump off yet, but I am expecting it is the oil pump issue.

    I think it is the gear hex style pump, especially as my local dealership did a supposed modification (they will not confirm to me today if it was gear or chain), I still have the warranty job paperwork. By the looks of it even a modification done by a dealer can fail, which I have not read on any site. By the way this site has the best info I have come across after a lot of searching.

    I can not afford to take it to Audi to dismantle, so my local indy is the first port of call, but if my fears come true and it is the pump, should I take it further with the dealer as only 50k ago I was told it was fixed?

    Not seeing the massive amount of coverage the has received since I never thought anymore about it, how can a dealer get away with a such a poor repair with a short lifespan. OK, it has not been since service by Audi but I have looked after the car well with the indy garage using the correct oil. Any thoughts? I have seen some options on auction-sites to get remanufactured parts - but how long will they last. I am looking for another 100k out if this car.

    I will update further on my progress, my local indy is already panicking about the job as he has done two before on older cars and pushed him to the edge... but until i know what the issue I do not know what option is best.

    Go back to the dealer. I think you have just cause and I suspect they either ill-fitted the new shaft or it was a previous designed shaft. As far as I am aware there have been a few modifications over the past few years and the most recent version will be newer than the one you had.

    As far as I'm aware the balance shaft was modified in 2010, to accommodate a longer hex. So you might have had gear conversion with the older part that is still known to fail. Audi should give a 2 year warrenty on the part they fitted, bit by the sound of it you are out or that too. Still worth contacting then, keeping calm, going on their Twitter facebook etc and politely letting then know. There might be some good will. Cheers matt

    Thanks for the support. I sent a letter to the dealership today but not holding my breath....- gave them a week to come back to me. May look to get a 100mm hex drive made locally if that will sort it. If the drive is looking worn inside will also replace that. Do you think it would be a good idea to replace the oil pump while it is in bits???. Its not going anywhere for aweek as indy is busy.

    Not crying yet, but can not believe Audi who I like can mess up a diesel engine so much..

    The chain driven unit in my BLB coded 2005 engine was converted to the "new" gear driven design by Audi in late 2011.
    The warranty on my unit is 24months with unlimited mileage.
    Hope this may help .

    Hi

    I have had no luck from Audi, i think they are just trying to put it all behind them and brush under the carpet..... There are people on ebay who are selling the full conversion kits, there are a few places around London who sell them. Parts list are available on this site but apparently they are on back order from Audi

    If you are worried I would just have it inspected and hope it is not the chain system as this seem to be guaranteed breakdown at some point..and the most costly if you want to convert. If it is the chain system you can buy replacement chains etc on ebay to do a quick fix, but it will go again. It seems BRE engines can be both chain and gear

    Looking on the bright side you are aware of the problem and if the LOW OIL PRESSURE light comes on just pull over as fast as you can and get it towed home, this was your engine and turbo should survive as i am hoping mine have.

    Good luck

    Except when you are doing motorway speeds, by the time the oil light comes on it has been the case the engine is totalled by the time the car is stopped.

    Ooh, not good.. I also have an 07 2.0 (with 67k on) and a bpw engine code.. I think that means we both have a geared oil pump (good) but possible issues around the hex key style balance shaft (bad). Would be very interested in hearing what happens with yours..

    There is a very good indy near me on south coast - where are you based?

    don't know about the bottom end as soon as the low oil pressure light came the engine was turned off, my local garage said that there was no oil pressure at all when he had it on his machine, saying that it could well be the pump, have spoke to Audi Uk the lad didn't seem to know to much & would not commit himself, i have asked for a manager to ring me but i am not holding my breath for him to ring me, but he did give me a price for a new oil pump £852.32 + vat, that’e without fitting,
    the engine number is BPW 078051
    i am based in east yorkshire

    Ive had my 2.0tdi a month and am seriously considering seeing if I can get a swap deal for a 2.0tfsi in the near future.. its not worth the hassle.. and mine is a BPW with gear driven unit so should be slightly better!

    Only do it if your keeping the car for a few years otherwise sell it!

    I had mine done last year and im thinking of selling in a month or so.. even if I get book value im down 2k

    So sell it 500 quid cheaper and move on! Dont make the same mistake as I did

    Thats good advice!
    I had my blb converted 12 months back for circa £2000 but only becauseI keep my cars for a LONG time and " in the family",
    10 years being typical. If I was one to keep my cars short term the maths behind the costs don't stack up.

    The safest way is to do what PaulB7 and me are doing and that is to convert over to a set of pedals and a bike chain ;)

    Hi guys,

    I'm trying to make light of this but from this thread all I manage to read is angry owners. The article from Audi driver is pretty defeatist any doesn't speak of preventative methods should you buy a car with low miles, only that you will experience a problem and you better save.

    I plan to buy a low mileage (32k) 56 reg 2.0TDi A4 in the knowledge it could have either type of pump, but hoping for the gear driven variant. Should it be gear driven I will be looking into replacing the hex bar with a custom made one should the pump still be in reasonable condition. If it IS the belt driven unit, i will be saving for a gear driven unit to replace it with - But to confirm, you can replace the belt drive system with the gear driven unit? Or am I totally on the wrong path here?

    Regards

    There are chain driven balance shaft/oil pump assemblies and gear driven balance shaft/oil pump assemblies only. The chain driven units (BLB engine codes ) can be converted to gear driven units. There are no belt driven units or I fear we would have other problems. Even the incompetent Audi engine designers didn't produce belt driven units.....................well not yet anyhow .......

    Yes Steve you can convert the unreliable chain driven system to the more reliable gear system. Most cars with engine codes other than BLB should be gear driven anyway, but check by ringing Audi a quoting reg a vin number
    You're still not out of the wood as the balance shaft as im sure you've read is still problematic
