Hi.
Thought I'd share my experience also. I have a 2005 2.0tdi A6, 150k miles. I've driven this car from new, never had any issues other than the usual cambelt changes etc. Had an sensor go a year ago, but nothing major.
Oil Pressure light came on on the motorway on Monday of this week, and stayed on. Rang my local specialist, who told me to stop straight away. Got the car towed to him via RAC (a long story for another thread!) after limping off the motorway for a few miles. Sure enough, it appears the oil pump has failed due to the issues raised in this thread.
I am looking at a bill of just under £2,000 to put things right with the retro fit kit. It appears at this early stage there is no other damage to the engine, so touch wood, no other costs will be involved. Like most other owners of this car, I had no reason to realise this was going to be an issue, until it presented itself to me - sounds like I've done well to get to over 150k miles before it happened.
Unfortunately for me, last month I had the cambelt done, so I'm pretty committed to getting the repair done and hoping I have a few years left in the old girl.
But of course the irksome thing is the circumstances surrounding Audi's actions here. I had a lengthy discussion with them this morning, In summary:
1. They wouldn't do anything for me because the car wasn't currently at a main dealer being looked at by their technicians. I said, "let's assume its at my local dealer now, and the problem is the problem, would you help me anyway?". The reply was no - partly because my last main dealer service was in 2010, and because they don't believe they should. Touché.
2. They said they have had a few isolated cases of this, hence why the modification was made. I told her that was simply not true and pointed her towards Google, and suggested a search term of "2.0TDI oil pump failure" to amend her opinion.
3. They didn't deem it necessary to do a recall of this engine to get the kit retro fitted. This was part of their constantly evolving engineering work, and happens all the time.
4. My Audi specialist chap says he's done several of these over the years. he also pointed out that Audi are the only ones making the kit, and it is priced very top dollar, because they know you have no alternatives.
It's a difficult one - I see both sides. I sounded off, and felt better for it, but there was nothing they were prepared to do. I would be happy to take some of the burden of fixing this, but having to pay over £1000 plus VAT for a kit (which can't be that substantial surely?) is the bit that hurts the most. You would think at the very lest, they would price these parts reasonably, if they didn't perform a recall.
If the total repair cost was a few hundred quid, I wouldn't be posting here now, but a £2k bill is a big pill to swallow. But then again, I'm not in a position to buy a replacement vehicle. Feeling more than angry at Audi now - this experience will certainly make me give Audi a wide berth when I do come to choosing my next car.
Obviously I've taken a dim view of all this, because I'm the poor mug faced with an unexpected large bill. But when the local specialist tells me that Audi should be hauled over the coals for this (and other similar things), then I do start to feel that they have behaved very underhandedly. His view of the situation is going to be more subjective than mine.
To feel screwed over by a company that I held "up there" in terms of quality and brand values, is a real kick in the teeth.
