Hi folks,
I am only after joining and thought I would say hello.
I will be doing my best to become an active member as I go along. Unfortunately at the moment I am battling with a stubborn BLB 2.0 tdi A6. New turbo fitted etc and trying to remedy that elusive chain drive oil pump that we were blessed with:(
Should anyone know of any posts that might point me in the right direction with my quest I would be very grateful and as I said, when I weather this storm I will be posting pictures and info on how I got on.I will however spare ye the close ups of bleeding knuckles and the likes!
Bye for now,

Hi

Hi there,
The turbo failed last week. I had a VAG com diagnostic done and was told the turbo was hammered. I went looking for a recon turbo and was told that it was a waste of time to fit one until I addressed the underlying problem of the oil pump. That opened a can of worms for me. I started looking into it and was shocked amount of issues out there.
I replaced the turbo and while she was in the garage I fitted new brake discs and pads. Oil and filter changed too. When I started her up today I was doing the usual start up checks when I heard a rattle from underneath as I was preparing to fit the covers. Alarm bells went off, as they would.
I now have the front stripped, down as far as the timing belt and am looking for a few pointers to see the next step. It sounds like a slack chain, albeit dampened by the noise of the engine itself. It seems to quieten slightly if I rev the car.This was only tried once or twice as I was concerned with the noise...and of course my new turbo.

Hi

Thanks for that.
I do intend to keep the car. Overall she is a good motor and I have no doubt that once this is sorted My wife will knock years out of it (99k milesat present)leaving me free to invest in another audi for myself. My current audi, 1995 80 tdi (1z) is feeling the strains of old age, high miles and our wonderful country roads in the west of Ireland.
As my username might suggest, I have a hankering for the urs6 2.2.I know, thats probably blasphemy on a turbodiesel site and will probably be doomed to eternal damnation for such talk!
Back to the job at hand.
Thanks again,

hi

After eventually removing the crankshaft pully for the timing belt I have reached Val Halla.
The tensioner was indeed broken. I have been lucky though, the cogs and the chain look to be unharmed. I removed the oil pump(why do they design a set up where the pump needs to be split to remove it?) and inspected the 6mm allen shaft drive. This was worn slightly on the balance shaft end.About 0.1mm worn off the points of the hex. I reversed this. The worn section is now in the oil pump where the hex is better supported and will not damage it further.
I will upload the pictures as soon as I can, this may help another poor soul at some stage.

I was quoted 2950 euro from an Audi specialist to sort this job.
So far, the costs have come in at:
Recon Turbo-700 euro
Timing belt and water pump will be fitted now that I have the stripping done-140 euro or so on E-Bay.
New,improved tensioner from Audi-60 euro.
Single use bolt for crankshaft pulley-9 euro
Sump sealant-Estimated at 30 euro.
Mental distress...priceless :bangshead:bangshead:bangshead

Overall, apart from the hidden bolts on the sump and the monumental torque needed to remove the single use bolt on the crankshaft it was a trouble free enough job.
Now, to put it all back together.....

hi

hi,
Are there other single use bolts?
Please advise as I am only ordering parts today and want to do a right job when I am doing it.
Thanks

What is the new improved tensioner like? Can you take a picture of the front and back?

The balance shaft module bolts are all single use stretch bolts. I don't know their part numbers because your engine may be slightly different and it would be a dealer item anyways. Take a look through the replacement procedure PARTS section and it has a listing that should help you.

hi

I will have the new tensioner on Saturday. The dealer will have it on friday but I am working away for the week. I will definately post pics of this and any relevant info, part numbers etc.
I did not realise the bolts for the balance shaft unit were single use. I had better order those three so. I did not remove the whole unit. Just the three for the oil pump.
