2.0 TDI oil pump / balance shaft failure?

ask if chain driven if it is, then you have a potential problem, tends to be > 80K miles though. intend sell it will be a trade in back to back to Audi _ for newer version
 
Suggest you call your local dealer and ask if the oil pump is gear driven or chain driven.

cheers will call dealer were i bought from to see if its got chain drive or gear
any idea if they will change it if it has chain,its got full audi service history and 2 months of audi warranty left,wishfull thinking i think
last week i took it to my local dealer,chesire oaks audi,they popped bonnet and noticed 2 other things that needed replacing,alternator pulley and egr valve,total cost just under £600 ouch!thank god i was covered by warranty
i quizzed mechanic about oil pump/balance shaft issues he said none he heard of???
dont know what to do,get rid or persist
 
hey guys spoke to dealer today,yep my car has the chain.its not been fixed,they will not fix it or swap for new part as there are no known issues,am not covered by there warranty if part fails,got 2 months audi warranty left
arghhhhhh
dont know what to do!

Your in exactly the same boat as me (although I now only have 1 month left on warranty). Audi UK are currently in contact with me (case is still open). The cost is just around £1500 for a conversion at my dealer. I'm going to get it done but obviously am pushing Audi UK to contribute but it doesn't look good.

From my point of view, the part will fail but the question is when. Unfortunately there is no way of damaging the chain while you have it under warranty unless you are a mad mechanic. The cost of swapping the car is higher than paying out to get the job done. I would write to Audi UK (customer service address which is a PO Box in Walsall) so that you have it registered and see what they say (they will assign you a case officer). If you get nowhere/still not happy then contact Watchdog and VOSA with your story. Be aware that the Watchdog officers are not going to know about this issue so give a background and brief details with references to the relevant forums for more info.

From my work in the customer service sector, don't start with all guns blazing.
 
we have a a4 s-line tdi with a bre engine with engine failure.
o6 plate on 22,140 miles

on the net we found out this engine was recall in july 2008 , just as we got the car from audi

the car been to audi 2010. will keep you posted on this

Don't think it'll be this though mate - It should only be BRB engines that are affected!
 
I am sorry to hear about an engine failure at only 22K miles - so much for the Audi quality!! Just to clarify, the chain tensioner problem does not include the BRE engines as the oil pump & balance shaft assembly on these engines is spur gear driven. The problem is on engines with the chain drive ie early BLB emgines. Also, the recall you refer to was related to a separate issue, the EGR oil cooler and I think that was just for the BRE engines.
 
I have enquired about the oil pump driven engine failures with my reliable non franchised Audi/VW dealer today ( whom I have used for the last 12 years and in whom I have the utmost confidence). I have been told they have only experienced oil pump related failures in two vehicles.One was a 2005 Passat tdi that was owned by one of the mechanics fathers.The engine expired at around the 45K mark and was a total write off and had to have a new engine.The second was on a 2006 A4 2.0 tdi that has 70k on ( this car is in the workshops now ! ).
Whilst not disputing the evidence to suggest oil pump related failures are an issue .The experience of my own Audi /VW mechanics is that they are not as common as generally believed and he has just serviced one regular customers early B7 2.0 tdi that has 230k plus on which has never had any major problems other than repeat a/c issues and a dodgy water pump. I hope this gives some comfort to all those worried early B7 owners out there that all is not lost and that owning an early B7 Tdi is not necessarilly going to be the "money pity" a lot of forum correspondence would have us believe.
I guess in summary we all need to be aware of the problem and listen ( on occassion) for the tell tale engine rattles but not let this detract from the joy of owning what are generally good cars.
 
Whilst I initially agree with you, the point that is important is that this chain that relies on a piece of plastic is never checked and you only find out there is a problem when the plastic sheers. To put a piece of plastic in such a deep part of the engine that is used to provide tension to a chain is heading for problems. Yes, there will be cars that don't suffer an issue but you've got to look at the ramifications if it goes wrong eg. engine seizing at 70-80mpg on a motorway.

The Passat's in America have the same issue, although the Passat's over here apparently didn't have the chain.

Audi must have known there was an issue to change the future components in the same model lineup to a component that costs over £500. I'm not going to take a chance and hopefully Audi will stump up an amount to get mine changed over.

So people have a number of options:

1) Keep your fingers crossed and hope it never goes wrong in which case you could be heading for a £7k bill that isn't covered by your insurance.
2) Get shot of your 2005 B7.
3) Get the chain renewed that would give you around an extra 70k.
4) Take an extended warranty but may end up forking out more for warranties than changing over.
5) Lodge a complaint with Audi, hope they'll help pay for you (you'll need Audi dealer history) or stump up the cash and be safe.

Numerous Dealerships know of the problem, my local dealer jumped straight on it and knew the problem like the back of his hand....

PS. Be aware that when your cambelt needs changing over, the possible added tension could put more strain on this chain and plastic!
 
I would generally agree Paul, from what I have read, it is not clear how common this problem is.

The reason this thread was started was to gauge if there was a more common problem, and if there was, to put pressure on Audi to come clean. I would guess that if the problem was really common, then there would be more stories here, and on other threads.

Also note that Audi say there is no known problem. However, I am not clear what they mean here as they know that some cars have problems as numerous owners have separately contacted them and had same response. Also my own Audi dealership knew all about the problem, but would not admit it in writing. ( i got this from mechanics and the parts department who have ordered numerous module replacements. ( he would not confirm numbers) I was also told there was a back order problem because of the numers of modues ordered arounf the world and demand for parts). Note, this is unchecked and was mentioned in another thread.

The jist of all this is that:

Yes there is a problem, and
Yes, it does NOT occur to all cars.

What % is very much unclear. Therefore if you are listening out to your engine from time to time, you will hear the rattle and this is ample warning to do something, either replace chain like myself, or change the module.
 
I have a 54 plate (blb engine) 2.0 tdi avant s line. Had it for 10 months, always had a slight rattle but being my first diesel thought it was normal! The car was previously an airport trasfer taxi so high milage (It's just done 140k) and local garage service history (not audi, & I have serviced it myself too). Less then a mile into my commute today engine lost all power and now REALLY noisy with rattling/cracking etc. Limped the car home and shut it off, the engine hasn't siezed. Kind of with I hadn't found this thread now! (or found it last week doh) so is it curtains for my then? Can I get an extended warranty from audi then take it too them next week ;0) if not then it's megabucks which I don't have. This was the most expensive car I've ever had as I needed reliability to commute further to work! Oh the irony.....
 
Thanks for that, seems like volksapart in sidcup maybe a good place to start. Is there any chance/point in looking into having my engine rebuilt? Or should I just go for a replacement? Seems like the parts to have it changed over from the chain drive to the spur drive type will cost round about the same as changing the engine for the type with the spur system already in? Would my engine need further parts also due to potential damage? (I guess there is no way of knowing without opening it up?)
Assuming that all blb engines have the crappy chain system can I just have a later coded engine fitted? If so which engine code(s) are suitable, and how does it effect the ecu ect when fitting a differantly coded engine? Is it still a straight swap? Can a vw/skoda/seat engine be used or just an Audi one?
Thanks , any advice much appreciated.
 
I should have said replace, i.e rebuilt engine but not your own, yes and try and get a 2006 + engine.

In terms of all the older posters, how are we all and what are you all up to, as you know i replaced the chain, what are you guys doing or have you done.

Some of you have the fear of something happening? i.e Nathan and others, have you decided what to do?

How many have written to Audi, Watchdog or other bodies, what has been the response?
 
Thanks for that, that's what I was thinking. So that's a BRE coded engine then? Will this just plug/bolt straight in? Or does everything need re coding ecu wise?
Has anyone already done this swap?
 
Weggie - I hope your repair has worked out OK. I am still waiting for mine to be completed having decided to go down the modification route, mainly becuase of the potential problems with the cranshaft sprocket and the tensioner 'weak link' in the system. The tensioner pretty much broke in the same place as others posted and the smaller sprocket teeth were almost worn flat!!! The sooner I get away from that design the better. Will let you know when I get mobile again, which is unlikely before the end of next week.
 
Brave man albearker01, who is doing your repair and for how much. I assume you are getting the timing belt and water pump done at same time as time wise it is very little diffeence, but you need to spend say £160 on the parts.

Note I had a fair bit of a debate with our American cousins on the TDi site under"qos fan" Oil hammer about replacing chain only or going for a gear system at £900 for parts. Oilhammer was not very positive on my decision to change the chain only. My reason was money 1st, second, I am low mileage per year, and thirdly a rebellious feeling on why i should be ripped off by Audi for over 2K when they ****** up the design on the engine in the first place. I really wish that we could get critical mass on these sites and get something on Audi for this **** via watchdog or small claims court.

The chain replacement and timing belt cost me about £450 to 500 in parts/ engine lift tools and oil, and stuff. No cost on labour, but note My friend and I took 2 days off each from work and one weekend. It was tricky to do , but asked if i would i do it again, i would probably say yes as there is some satisfaction and interest in how cars are put together, but ****** hard work. I also know it could go again i.e chain but top sprocket was OK. Oil hammers comments are worth reading do a google search for his name and QOS fan and you will see the debate on the TDi site!!!!!

The car seems OK at moment, but as i say, i am low mileage so I really hope I get 30 to 40,000 miles, then i trade in back to audi, they can have the ****** car and its engine design!!!

Hope things go well for you, i am sure they will, and that the cost is not too high

Still going through the motions with Audi. Haven't Watchdog'd yet as I want to give Audi a reasonable chance of making amends.
 
Hi 1 for t road. Did you have the rattle? Did you get a quote, I assume you are replacing to the gear system?. Is the repair with Audi? R you replacing timing belt, the kit and water pump.

The reason i ask is t get a definitive range of repair costs. the gear seems to be about £800 from Audi. I got a message from someone who reckoned he could get it cheaper, but i did not pursue as i only replaced the chain.

When complete, can you can get an idea of the tie the charged, i.e hrs and rates. Have they done the repair before as the top sprocket is a ****** to come off. need speacial adopated pullers and heated up to red hot to get off.

PS did you try to get goodwill off audi?
 
Hi weggie
audi gave me a quote for the balance shaft repair £1.189.36p inc labour , we bid try for the goodwill but will have to wait and see:icon_thumright:
 
I am amazed at this price, where is the garage! is it a dealership or indy. Allot of guys on here might want to use it.

My experience was that the new balance shaft housing, which is part no A03G 103 295L was going to be £719.03 excl VAT. Out of interest can you find out what they are charging for this as I got my quote directly from Audi and someone else i spoke to got the same price. There are two new gears required for£50.00 Also you will need new synthetic oil say£40 and a fliter say £7. New coolant and power steering fluid will also be required.

If you are doing this work, make sure you do the timing belt and kit as well as water pump. it will not be much more in labour as it involves taking the front end off and you will be doing this anyway, it is meant to be done at 75,000 miles. I guess about £150 for belt and kit and say £40 for the water pump.

If you take account of all these parts then there would not be much change form your £1189.36. So their labour must be very little. I reckon a garage will charge about 10 hrs at say £70 so a further £700.

One Question or thought is that you might be only getting the replacement of the chain, like i recently did, the chain and tensioner is only £70. If you include the labour and parts i mentioned this would be about £1200 incl vat.
 
UPDATE

Audi are not going to offer any goodwill to me on the basis that they don't believe there is a fault and there is nothing wrong with mine (yet!?). Because my car is having it's cambelt and water pump changed, I've swalllowed a hard pill and am forking out for the modification which I suspected I'd have to do. Apparently there are no other recent cases at Audi UK of this problem so either they are telling me porkie pies or very few/no people on the forums have sent in letters to Audi.

I am now going to complain further up the chain (pardon the pun) and enclose all the details I can find. I'll also be submitting a report to Watchdog. I cannot go to VOSA as I haven't had the problem.

So, to all those people who have had, worried about and are currently having this problem fixed, PLEASE, PLEASE, contact Audi UK at: P.O Box 400, Walsall, West Midlands WS5 4XX. If you have had or are currently having the issue then contact Watchdog with a brief summary of what's gone on.
 
Nathan, I got same message from Audi UK, me thinks they are liars!!. I also wrote to VOSA, they are only interested in safety and the chain snapping is not deemed to be a safety issue. I also contacted Watchdog.

Have you got a quote for your proposed repair, I see 1 for the roads quote is cheap, perhaps to heap, possibly only chain replacement.

How many times were you in contact with Audi UK, i wrote and spoke to them 3 or 4 times, they would not budge, would not offer me a penny. I cannot believe they can get away with this problem. I assume you quoted the magazine article as well to them?
 
Quoted everything I could. Was in contact for over a month, car had to go in for cambelt in any case so if it was going to get the work done it seemed best to get it done at the same time. Cambelt+waterpump+new assembly - £2k! Dealer said they can't get the chain part and could only swap over to the new one. Now going to write to the CEO and including information on everyone's car that they have publicly posted as I got very few emails.
 
If you do want to go for the chain replacement I can get you a chain from my dealer, chain and tensioner is about £70. I Got one 3 weeks ago & car now sounds fine. The debate then is how long this repair will last, or if you believe Audi, it should last for a very long time as there is no known problem with the chain!!!!!!.

Your quote of 2k is much like mine to do so I guess 1 for t roads quote of 1.1K must be the chain replacement.

To do the chain you only have to spend about 4 hrs or so more work compared to the timing belt and water pump, this involves taking the sump off and a number of other bits like anti role bar and unbolt wishbones to get to the sump. You might even get an indi to do the work and save your self a bit, but you may be thinking of your service book.
 
hey guys can someone remove my vin number from one of the posts?
many thanks
 
Think you will have to remove it yourself as it was your original post if we are talking about post 115
tried but wont let me,no options to edit etc,any mods help me remove?many thanks
as to update to my situation,dealer where i bought car from,spoke to service manager,she has worked there 5 years and had no problems with chain drive oil pump failure etc,quote"i do all the bookings,not had one in with this problem or even heard of it etc",warrington audi,so i ask my local dealer cheshire oaks,about problem,the service manager more helpful,theyve had failures but wouldnt say it was direct fault with chain etc,she said she would chase it up with audi customer services for me but havent heard back from her,also spoke to tech at said garage,he has no knowledge of said problems with the blb engine code etc
so after 5 phone calls to audi uk,they have my concerns logged down,they say they will see what they can do,keep saying someone will be in touch etc,3 weeks now nothing,ive had enough,too scared to drive car,soooo dissappointed with this,love the car but cant swallow having to pay near 2k to switch to gear drive and do cambelt aswell,why should i?soo angry,other option would be extended warranty but thats £700!what if it fails and they say its wear and tear?and i have to end up paying!not having that
so im gona trade it in,had enough,dont want the hassle,good luck guys on what yous decide to do
 
To be fair the 2k includes the cambelt and water pump. I'm working on the principle that I am going to push as far as I can, not necessarily for myself, but so others may get more assistance in future. I can't fault Audi UK's customer service team, they phoned the day they got my letter and assigned me a case officer however, I would recommend writing to them initially so they *have* to log it. If owners don't contact Audi UK then the people that have registered the problem will find it harder to fight as the numbers aren't there and don't rely on the dealers logging it with Audi UK!

I for one am not trading my car in as it will cost more to get a newer version of my car with the same spec than to pay for the mod. I'm not happy with having to fork out for a hidden cost but rather not spend more money and possibly find out that later cars have their own faults.
 
Just joined

Taking delivery of the 2005 BLB Friday. Three months warranty. I am really worried. have paid £500 deposit against £10k purchase price. Price includes service, cam belt, water pump.

What should I do. It has full Audi service history and MOY to 10 Jan 2011. The Audid dealer said it was without problem when it was MOT'd

Nerves are dangling.
 
I'd love to say don't worry about it but I think the plastic tensioner is failing more to do with time than mileage. You have various options:

1) Keep some cash set aside, if you get the rattly symptoms then stop the car immediately and be ready for a £1500 bill.
2) Get your money back and buy a more recent car.
3) Take an extended warranty, Audi's is around £800/year, third party companies offer it far cheaper but maybe harder to get them to pay out.
4) Get it converted over to the new system when you get some cash.
5) Swap over to a new chain and this should buy you another 5 years/80,000 miles.

Be aware that that chain is *never* checked as part of any service so you can not easily check on it's wear and tear.
 
Ripp4U,

Wraths advice nicely summarises your options but I would ask you to read my earlier post in this thread,post 129.
Owning a new car ( albeit a new but used car) should be a pleasurable experience and not clouded with worry from the onset of ownership.
If you are by nature a worrier DO NOT GET THE CAR as it will make your life a misery.
Please take this advice in the spirit it is intended. I for one really like my BLB engined 05 Avant and plan to keep it for at least three more years until I get to the 100k mark before moving on to another vehicle.That said I am not going to be worrying about an oil pump failure. If it fails so be it and I will tackle the issue as , when or IF it happens.
For now I just enjoy driving my car and listen periodically for any untoward noise.Like any responsible owner does with any car.................

Good luck with your decision and I hope you make the right one for you .

I agree with both Wrath and Paul.

One thing i noted is that you say "Price includes service, cam belt, water pump." Does this mean that they have still to do this work? if so i suggest you spend the extra cost in asking them to remove the sump and check chain wear, if worn, then change. See post 147. You could also play the game you are wanting to pull out, and negotiate a reduced price for the above extra work.

What mileage is the car, is it from an Audi dealer, does it have full "audi" service history. if so another tactic is to get an agreement on this failure, if Audi say there is no known problem, then surely they should accept this option !!!!!!

I also think that there must a be a cooling off period so you could pull out and ask for deposit back, try citizens advice on this.
 
Can I just replace the chain now it's snapped? Or will the engine be damaged? Suppose there is no way of checking without taking it all to bits anyway? The engine hasn't siesed. Any suggestions for a good place to supply/fit a replacemant engine if that's my only real option? Will a later coded engine (with the newer gear system) just bolt straight in without any problems?
Cheers.

How do you know chain has snapped?.Has someone looked at it since your post last week? You said you ran it home, if chain had snapped i think engine may be ******

I would tow to your local indi if you are not sure. if sure, I suggesta possible new engine, check out my post 133, did you ask TT about newer engine bolting on, i don't see an issue myself.

Note TT said to someone that you may need new turbo as well.

Not sure where your from but if your relatively north then AW Engineering in Darwen recondition engines and can provide replacement engines and parts (they specialize in VAG only diesel engines ONLY)

http://www.vwenginerecon.co.uk _ Sorry just noted Suffolk.

You could give them a call to get your questions answered, they may know of other places in your own area or try http://www.reconditioned-engines.co.uk l. tel 08454 666 009. Thinkquote will be 1500 and i think they are London, they also pick up car.

Let us know how you get on.

I recon that if you have registered concern with Audi and then get the problem and big cost your should do the following.
1.Before the repair is tackled Notify Audi in writing by recorded post asking for financial assistance. Enclose photo copies of ALL records of service evidence.
2. If Audi decline. Write again recorded and make a formal claim to be acknowledged and agreed in 14 days.
3.Have job done send receipt copy to Audi
4. If no good. Finally put in a Small Claims to the County Court .

I think they will just pay up to avoid their legal costs and adverse publicity.
 
Had a quote from reconditinedengines.com came in at just under £2400! They guy said they wouldn't fit a replacement, just recondition the current one (hence the website name I suppose). I'm still waiting to hear from volksapart. I havnt taken it anywhere to have it diagnosed but don't see how they could without taking it all apart? And that = even more cost. It has been rattling ever since I've had it, now it sounds like a bag of rusty hammers like there is a loose chain thrashing around inside, and no power. Can't see what else it could be? Thanks for your reply, I think you're correct & pretty sure it's a replacement engine for me!
