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.

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.
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.
I'm just about to buy an 08 2.0 diesel automatic A4 (25k on the clock). From reading this thread I'm a bit worried. Does this fault apply to all A4 B7 Audis? Is there anything I can check to see if this is likely to occur in the car I am buying?? Any advice would be great, as I don't want to end up spending a load of money on fixing a newish car.
Just a point I felt needed clarifying. The BLB issue isn't the oil pump failing, it's the chain/pre-tensioner and hex shaft that causes the issue. Other engines don't use the same system.
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

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?
