    This thread relates to the 2005-2006 BLB engine codes where the oil pump is driven by a chain and pre-tensioner. Later models used a gear driven mechanism that is far more reliable, in fact I think all the VAG 2.0TDI's use it.

    Thanks for clarifying - was starting to wonder whether we'd made the right choice.

    What is with the "its only 05-06 BLB engines"?
    My 57 plate 2.0 tdi BRD is looking at a £2000 fix for oil pump drive failure.
    Same story, no spares, just a complete, revised pump assembly and modified sump, plus other consumables. Audi estimate £1500 spares and 6 hours for really expensive labour. £570 or so. Plus VAT.
    £98 plus VAT just to diagnose and quote. Unbelievable!
    At 3.5 years old with just 60000 miles, they advised today that I could apply to Audi UK for a goodwill gesture to reduce the cost.
    Bearing in mind, this is just to fix the pump. When there is some oil, they will be able to look for damage caused by the previous lack of it.

    Not to scare you but this is what happened to me. Started off oil pump and turbo. Replaced and started engine only to find engine was ruined.
    Car had been driven 30 seconds with oil pressure light showing, as I was on main road.

    I think the damage to my engine was pieces of broken turbo. The oil pump goes, which is fixed to balance shaft and then turbo doesnt get cooled via oil.

    The BLB engine is chain driven, the BRE is sprocket driven ( i think ) but why do all engines break??? BLB,BRE,BRD ????

    Anyway I was looking at £8800 for new engine and turbo and £2600 for diagnose and stripped down of broken engine. So £10K

    Happy days

    Hi Wrath.
    Interested to read your recent comments, but my BRE engine failed (see post 351). Audi replaced at shared cost my entire engine and turbo, and the car is running again as before.

    The fault was described to me by a local independent as a hexagonal drive shaft wearing round where it fits into a round hole with narrow groves. Inevitably when the wear takes place the pump, and then turbo and then the engine fail.

    This whole proceedure is described in Audi Driver magazine in their May 2009 issue on page 18 in the "Technical View" section. I can email a copy if anyone is interested ( robert at ejhales dot co dot uk ). It says that because the drive shaft fails gradually, most of the damage to the engine is done before the oil light comes on - so unless you are aware of the issue there is nothing you can do to avaoid it.

    Wrath - I would be interested to hear your further comments. It seems to me this design was doomed to failure - and Audi should pay in full for the entirely forseeable repairs that they have caused. Worse, Audi know these engines will fail eventually, but have failed to advise their customers who could have taken precautions, according to the article.

    The engine number for the car is BRE 148125 and it sounds like this is potentially at risk of this problem. As the car has only 25k on the clock, I would be surprised to see it have an issue yet. However, is there anything that I or Audi can do to prevent this from becoming a problem on the car?

    I'll got some Audi documentation regarding the fault on the BRE engine, early BRE engine cars had issues with gears wearing and the shaft to drive the oil pump was incorrect (they fitted the wrong part according to this information I have). Thankfully my BRE engine was not affected by this but I'm still not taking any chances, I'm going to drop the sump and replace the oil pump & shaft, as these were both revised last year!.

    hi guys. Well i'm starting to get afraid of this happening to me now. I have purchased one a month ago (A4 2.0Tdi 140 2005) with BLB engine code. It does have full service history and now has 73 k on the clock.
    As soon as I got it I had it serviced and timing belt done, Then a week later the turbo failed! (Blue smoke from exaust). The dealer I got it from had it repaired, don't know how much it cost him.
    Reading this thread got me wondering if the turbo failed because of low oil pressure??? And maybe the oil pump shaft is on it's way? Now it's out of warranty and i'm thinking of trying to just sell it! What do you guys think?
    The engine does sound good, no rattling. Do all BRB engines suffer from this flaw?

    Update to my 57 plate BRD (170 ps) oil pump failure....
    60000 miles full Audi service history and oil pump failure.

    Sorry to take away all confidence from anyone who has put on the new version of the oil pump assembly....but....
    My BRD engine had the gear and shaft drive that Audi has been fitting as a replacement to the chain drive system.
    The new, revised £800 assembly supplied had a fractionally different casting but was essentially the same and had exactly the same useless hex drive to the pump that wears and fails. The NEW unit has so much slop / backlash in the hex drive at the pump end that it is going to wear fast and has absolutely no improvement to the failed unit that failed. (An AUDI service dept confirmed that they all have slop / backlash in the hex drive from new, as we thought we had a faulty replacement part.)
    ALL 2.0 TDI engines, whether you have the weak chain drive or current gear and shaft drive have inherrent weaknesses and will fail!!
    My old balancer assembly and pump actually work, it is a poxy 100mm long bit of hexagonal steel that is worn. You can turn it around to use the non worn end at the sloppy pump end or have a better piece of hexangonal steel manufactured for less that £800!!
    Paying £800 for an essentially identical balancer / pump unit just for the hex drive is rediculous.
    Despite knowing that there is a weakness in the drive to the oil pump that fails with potentially catastrophic consequences, AUDI are still shipping replacement assemblies with exactly the same weakness today!!!!
    The tool to align the balancer shafts when you fit the assembly is available for £12.

    My conslusion is fix the car and part-ex it on something other than an AUDI. This is from a serial Audi buyer that has just been to LeMans to support AUDI.... IN MY VAN.... because the car is still on the ramp. On the weekend I spoke to everyone I saw with an 2.0 TDI and I plan on being a one man marketing disaster for AUDI.

    hello everyone, just an update.. my engineer, who is part genius, part ferrari tech, and part master engineer, has modified my worn balance shaft assembly so the hex shaft now fits nice and snug..its so simple you wonder why audi didnt do it this way originally..was it meant to fail or am i being cynical..(who me)...just think how much audi have made from all the suckers that buy this car thinking its invincible...come on audi...front up and grow some balls..its us that are paying for your mistakes...remember what poor customer service did to lancia... could audi be the new lancia i wonder...perhaps then somebody may bother to remember that the customer is king and shoddy service and goods just get chucked in historys bin....i hope the audi that crashed at le mans on sunday didnt have a sheared oil pump drive shaft??? no i suppose we shall never know.i shall update you all soon on my lancia a4 repair...much love..etc etc

    From what i have read on other forums the 2.0 tdi is a BAD engine the newer engines are now failing once they get to the 60,0000 mile and above,
    when i first came on this forum it was mostly BLB engines but now the newer cars are getting older its most of the 2.0tdi engines fitted with a hex drive to balance shaft that will fail ,

    if i would have seen this forum before i bought my car i could have saved myself 3 grand

    hi my dad has a 55 audi a4 2.0 tdi has just had major work done due to balance shaft module failure, needed new sump, turbo, balance shaft module etc loads of extras ran into a couple of thousands of pounds. ihe is in dispute with audi about a contribution towards repairs as it should have been a recal. i have set up a group on facebook called: AUDI(NOT THE QUALITY CAR THEY ADVERTISE) please join and give some support as it will help with ongoing dispute with audi, also would like to hear of your own problems and experiences.

    I was looking at A4 2.0 TDi's aswell, but this thread has totally put me off, and I'm guessing the problem is the same accross the VAG range with the 2.0 tdi unit fitted right?

    Might have to look for a V6 3.0 tdi instead or even an oldschool 1.9 in an older model.

    hi all, got my modified oil pump drive up and running for a week now, fantastic job by my friend and fellow mechanic...only snag was it blew an intercooler.. dont think it was used to the oil pressure haha.. all ok now ..runs fine and dandy..and really it was such a simple modification..if i get another a4 i will just get the mod done anyway..all i have to do is get my 3rd dual mass flywheel changed and it will almost run silently..i rang L.U.K (the dual mass flywheel maker) in leamington , and they denied having a problem with them and it must be my fault..just the 3 for me then....in the whole world...wow i feel special..i think the secret is plenty of nice additives in the oil and switch off very quickly when your shaft rounds off... on an interesting note , my wizard friend is currently changing the blown starter on a bentley sport..they quoted 950 for the starter on its own...it took him 2 days to get the engine and transmission assembly out to access the starter, then strip the mountings to get starter away from engine...its a tourag w12 starter or a passat pheaton.. part number available but we cant sell you one..its bentley only supplied....short and curlys anyone...(bentley sport is an Audi A8 in another skin)..i love my car but i wish it wasnt so unreliable..still thats what i spent my 33 grand on.. tough ..if only i had a 5 year warranty like a kia...or a lifetime like a vauxhall..silly me i went for solid reliability... good luck everyone..lets be carefull out there

    hi ppl, i have a Audi A4 2.0TDI with the dreaded BLB engine. my car is at 116k and i havent had a problem with the balance shaft at the moment. its got full audi service and i just wanted to know what i need to hear or look out for. are there any signs before it happens. i know about the oil pressure light but i mean does the car drive any different or any noise i need to look out for?

    sorry but the car does vibrate in idle. i have had the clutch and flywheel changed by a specialist a few months a go and that didnt help the vibrating. any help would be nice

    thanks

    hi raff, best thing i can reccommend is a good oil additive like molybedenum from halfords.. its expensive but it saves your engine if the shaft goes when your flying...as soon as you get 3 bleeps from the dash and the no oil pressure warning comes on, just kill the engine.. the additive coats the bearings and you may save your engine.. also try an injector cleaner additive in the diesel..i assume all filters have been changed etc air -fuel etc.. is the vibrating just rough tickover , or is it like a misfire?? i had glow plugs changed and the audi tech( haha) broke my injector supply loom letting the oil get in and the misfire happened...

    Thanks for the reply. No the vibrating can be felt on the steering wheel. I was told by audi when I got it serviced that it was most likely a DMF but had that change which made no difference. Steelers for ya :-) I've tried all the different injecter cleaners n Fillters were all done at major service. I guess I will drive it till it breaks. Lol. Just need to tell the mrs about the oil pressure warming:-)

    hummm...ive just bought a 2005 a4 avant tdi 140 with the dreaded blb engine, in fact im picking it up in the mourning. i had a phone call off the trader, he told me the oil pump had gone on it and was costing him 2k to put right. hence why i didnt get it today witch was the origanol plan.

    when i went to view the car week last wednesday, i checked it over, did a hpi and drove it, and fell in love, the drive of it was abersultly goregous, could'nt fault it. only problem was the rattle in the engine, but it turned out to be chaine rattling, eventually it went bang and killed the turbo, its been repaired at his expense having a new pump and turbo and there will b a 12 mounth warrenty on it, maybie im lucky?

    before i part with my cash, im going to have to review it, is there anything i need to look out for?? could there be possible damage to the engine??? is it likely to go again in the near future?

    reading this thread sould make me walk away but i cant, i really fallen for this car!!!!!

    With the BLB engine you will need the oil pump/balancer assembly £800 plus VAT, modified sump as the shape is different from yours. Turbo £800 plus VAT unless he's getting yours refurbished. Plus a lot of labour. You have drop all of the subframe and suspent the engine and gearbox from the wings. Remove air con and plenty more. If he can do it properly including turbo for £2000 he will have a queue forming infront of his workshop soon. Those are pretty much cost prices, no profit margin. He also needs to buy the correct tools for timing it all back up.

    Dont forget that the new balancer/oil pump assembly that needs to be fitted is also sh*t. I had the new gear driven version and it failed at 60000 miles. The £800 replacement had the same poxy hex drive that rounds and fails. ie the new assembly has not been improved by Audi despite them knowing that it ruins engines. I thought my engine was fine after replacing the oil pump as it was only pootling along at about 40mph when it failed. Did about 30 miles before I started getting a "wooo" noise on turbo boost and overrun. Looks like it needs a new turbo.
    You will be able to tell if he has put in a new oil pump because he will have had to fit a new sump. It more difficult to see what has been done to the turbo as it's buried under the air box ducting on the left, he may also have fitted a recon turbo.
    If he does a good job you will have a good car until the hex shaft to the oil pump goes round, then you will be back here cursing the sh*t design and lack of accountability from VW/Audi.

    was suppose to have her today but something went wrong!

    i got a phone call last night from the trader to say he's had the car back, but after the work was done, the whole dash board was all lit up, oil light glow plugs etc! and after reading the horror storys, common sense should say it was a good time to pull out :-(
    he also has a B6 sport 1.9tdi avant so i suppose i'd go down there to view that and also see what was going on! anyway got down there, view the B6 and it was a nail! however the B7 the one i was origanally going to buy with this issue was also there. looking rather sexy!
    the trader said he wont let the car go with the dash lights lit up and wants the car 150% before sale, witch seems pretty decent of him.

    we started the car up and it was running abserlutly bob on, the bad rattle has gone but the engine management light was on, and the little reader display in between the clocks was going mad, oil light and oil pressure problem, so we drove to audi, he bought an oil sensor, took it to his local garage to get it fitted, bit of a bonus for me really, while the car was on the ramps, i was able to look underneath. no word of a lie but it was spotless under the car, u could eat your dinner off it witch is quite unusaul considering it has 115k on the clock! you can tell the work was carried out because the sump looked band new! once the sensor was replaced, the car was pluged into a computer, reset all the fault codes, compleatly cleared the the lights, tho as soon as we drove off again, the reader display started bleeping saying something about the oil pressure! the car has done about 300 mile since the work was done, surly the engine would of blown up by now??? so the car has gone back to the garage were the oil pump, turbo and injector was done and ive walked away with my deposite back absulutly gutted :-(

    i dont kno what to do, the dealer seems genuine. he doesnt want to sell a dodgy car, the car is strait as a die, i can see that myself, i hpi checked it and come back ok as well as vin numbers, and the v5 cetificate number matchers, it has full audi history, cam belt chainged etc, it runs beutifully, no noisers knocks etc and the body work is spotless! as for this common blb engine fault, its getting delt with at his expence with a receapt & 12 mounth warrenty (even tho its been done at the other side of the country from were i live) but is it likely to go again in a hurry? or is it one of these that goes evey 100k?

    this is the car i can only dream of! 05 reg black a4 avant s-line 2.0 tdi 140bhp, and its going for 6k witch is all i can afford, not going to find another one like that for that kind of money! im gutted, was really looking forward to having this car

    reading ellwoodblues's horror story but yet he has a 2005 with the bre engine code

    good god what happend to the good solid bomb proof audi! whats going on with these so called clever germans??? bring back the old 80s and 100s i say

    Yes it will be a "safer" bet, however, people with later engines have suffered from the gears breaking up and ending up with the same serious issue. Maybe someone can find out why Audi introduced some new balancer shaft parts in December 2010 for all the 2.0 TDI B7 engines (look on ETKA)? Maybe some clever soul recognised a fault with them and they fixed it.

    How are they a safer bet?? Have read of some of my posts on this page and then ask yourself if the later BRE or 170ps BRD engine are a safer bet.
    If anything they are worse!! They fail from 60000 miles. With the BLB engines you get a sudden oil pressure failure, with the BRE, the hex shaft rounds and slips. This slipping drops your oil pressure but only sets off the warning when it really can turn the pump no more.
    When it finally sets off your warning light your turbo has already been running with low oil pressure for an unknown length of time.
    Both of these engines have the later version of the balancer/oil pump assembly which they are upgrading the BLB motors with once the original has failed.

    The housing of the balancer/oil pump assembly was recently modified slightly, the new spare part now has a few less bolts holding the casting together. BUT, the weak point....the hex drive to the oil pump inside the unit is EXACTLTY THE SAME, NOT CHANGED, IDENTICAL, RUBBISH.
    The hex shaft has slop where it locates into the oil pump, it will wear fast and will fail!

    I sense the annoyed tone in your writing. Please remember that I have been recording BLB failures and have read your posts.

    Engines later than BLB are a safer bet because the BLB's not only have the same hex drive but also rely on a piece of plastic to provide tension. I have a BLB recorded as failing at 43,000 miles! I am not suggesting that the later 2.0TDI's have no faults but I am stating that the BLB's are worse than all the later models because they have more failing components. There are BLBs recorded has having the hex drive failing without the plastic tensioner failing.

    Is that okay, anyone else want to jump down my throat?

    afternoon all. mine seems to be running well now , well at least until the next bit of bomb proof german engineering goes belly up.. had it up on the ramp to check for leaks and just a check , and found a perished rear flexible brake hose just ready to pop so you may all want to have a peek under yours..all the engine probs usually happen at 80,000 miles..i can prove that as i have done 240,000 and its happened 3 times..funny that as warranty is 60 thousand ....makes you think..keep smiling everyone ..

    I was not intending to wind you up Nathan. I'm just keen that nobody is left with the false impression that the later engines are free from oil pump failure. You are correct, the BRE and BRD do not have a plastic chain guide to break.
    My annoyance is not with you. It is with VAG for not fixing this problem when it has been known about for many years. I have read earlier pages on this thread where people have talked about upgrading to the latest gear driven system as a cure. When infact they are upgrading to system that is still going to fail sooner or later.

    My A4 Avant S-Line with the 2.0 TDI BLB engine reported low oil pressure as I was driving it on Tuesday morning. I immediately turned off the engine and had it towed the my local franchies Audi dealer, where I have had the car serviced since owning it.

    I requested diagnostics (at around £100) and received a call later in the day from the Service Manager, confirming that the engine was suffering from low oil pressure. The suggested fix in the first instance was to replace the oil pump at a cost of £1500 including VAT. I called them back the next day and was told by the Service Manager that Audi had offered a 50% goodwill contribution - the car has covered just over 162,000 miles!

    My response was to ask for a breakdown of what will be replaced as part of the £1500 repair, if Audi follow through on their goodwill gesture then I am willing to risk £750 dependent on wihch parts will be replaced.

    Will keep you posted.

    I have been, and still very much am, a one-man marketing disaster for Audi. since my 2005 Audi 2.0 Ltr Tdi,that I have owned from new, had the chain-driven Balance Shaft break in March this year.I am in dispute with Audi and am carrying out protests currently. It is clear,in my opinion, that Audi should have done a recall or at the very least put their hands up, carried out repairs and satisfied all these previously happy Audi owners, me being one of them!.

    That doesn't sound like a bad deal. Fixed for free due to design fault would be better. However, I hope I'm wrong but the £1500 quoted is parts I recon. Probably plus 5 or 6 hours really expensive labour. It's not a simple job.
    I was doing 40 or so mph and shut down straight away, turbo is being replaced as it now makes a "woooo" howling noise on boost and overrun as the bearings were starved and the veins now brush the housing.

    I'm less concerned about my turbo than I am about the block and head - was there any apparent damage to yours?

    I haven't had the motor apart to check, just replaced the pump/balancer assembly and gave it a test drive. It was not down on power and sounded fine. It's possible that there has been some wear on obvious areas. I can't imagine too much trouble as it did no mileage after the warning light came on, having said that the turbo is knackered and I was hoping that would have survived.
    I have posted previously that the BLB chain failure is a sudden, complete fail. The hex drive failure as it goes round can reduce oil pressure as it starts to slip before it gives up totally. I recon my turbo was running without enough oil pressure for quite a while (maybe months) before the warning came on. Your chain would have been driving the pump properly (maybe with a bit of noise) until it suddenly failed. Let's hope you got away with it.
    The turbo is not as expensive as I was expecting. It's with Turbo Technics for assessment and possible refurb. No verdict yet.

    I'm trying to put my mind at rest by thinking about the number of cold starts the engine would have done during its 160k mile lifetime...picking car up next weekend and will post once I've had a chance to road test it and clock up some miles.

    If the turbo is blown I may have to resist the temptation to replace it with a hybrid, replace the DMF with a solid conversion and get it remapped...

    Are most of you saying stay away from the 2.0 TDI? Is the 1.9 ok?
