2005 Audi A6 SE TDI 2.0 turbo diesel


Terrible engine, awful car


This is without doubt, the worst car I have ever owned.

At 56k, the small bit of plastic that keeps the belt secured to the oil pump snapped. This caused the oil pump to stop pumping oil around the engine. It totally killed the car; the engine seized, the turbo blew, and one injector packed up. The total cost for repair was well over £4k.

Never ever buy a BLB VAG 2.0 TDI engine. Search Google for 2.0 TDI oil problems, and just look at the number of people who have suffered the same fate as me.

I am writing this in the hope that if you are considering buying any car that uses the 2.0 TDI engine from 2004 to 2005 (it was updated in 2006), and this includes Audi, VW and Seat - DO NOT.

This is a design fault with the engine; do not buy one and hope for the best as I did.

General Comments:

Apart from the engine falling out, the steering was too light. This wasn't a fault, and might be down to the fact I'm used to BMW.

I hated this car, and glad it is out of my life.

Would you buy another car from this manufacturer? No

That's too bad. I had the old '97 1.9L TDI, and for once VAG had a pretty good reliable product, other than the control electronics.

It will be interesting to see if these high sales numbers will translate into major sales losses, in the future. VAG doesn't appear to be interested in quality and reliability. Then they go and sell replacement parts at atrociously high prices and the dealers soak you for all you got, only to find out that it didn't even address the problems you were having. To be fair, the original dealer that I bought my VW from had integrity and they never mislead me. Unfortunately, they went out of business and I had to take my vehicle to a non-dealer shop for service. I then started doing it all myself.

"VAG doesn't appear to be interested in quality and reliability."

They aren't the only manufacturer.

I agree, a total rubbish car. Defies logic how a "premium" car manufacturer can produce a sloppy effort. The design of the ill fated oil pump chain tensioner is amateur enough, but the drive from the balancing shafts to the oil pump itself is disgraceful..... Having a six point drive (Allen key for want of a better description) driven by a TWELVE point female socket from the balancing shaft is beyond belief. Square peg... round hole jumps to mind.... The points of the Allen key wear and bang!!!

The BLB engine is the pits, I have struggled with one for long enough, with absolutely no help from Audi Ireland. The over priced, badly built, average performance electrical and mechanical nightmare will be moved on as soon as the final payment is made.

Be aware though, all 2.0 TDI lumps have the Allen key drive to the oil pump.

Power steering hoses exploded, window regulators failed, handbrake loom failed, turbo failed, throttle actuator failed... need I go on?

After driving Audi for 15 years - the 1.9 TDI was a cracking engine to be fair - I will never ever have anything to do with Audi again.

Proper German quality from now on. Merc or BMW from now on.

Can I clarify something, you state the A6 in general is awful and advise against buying one, but your problems are down to the 2.0 TDI, which is a known issue. So can you be clear, the car is fine, but the engine is the dodo?
