I bought a used Audi A8 last year, 2003 model with 50k on the clock. I got 12 month dealer warranty which expired 6 weeks ago. The car has now developed a fault and I have been told they need to strip down the engine to replace the cylinder head. They are quoting me £6000 for the job! Anyone else had similar problems and is this a justifiable cost, given that cars of this nature should be doing in excess of 100k miles before requiring major 'surgery' - or am I being deluded? Any advice would be appreciated

Sorry to hear about your troubles. Have you checked with an independent?

Out of interest, was it a 3.7 V8?

Go to an independant, exactly what is the diagnosis?

Arent the V8's fitted with 4 pot golf heads??

A VW dealer will be cheaper than Audi. An Indie will be cheaper still for a rebuild.

Or you could buy an entire new engine for less and swap it in?

I have been told by my dealer that the timing chains have elongated, driving the pistons upwards and damaging the hydraulic tapets (?). They have admitted that they would not expect to see this problem on a A8 2003 model with just 55k on the clock and have offered to fund 30% of the overall cost which is obviously an improved position but I will still push for more. This has seriously undermined my faith and confidence in Audi

Give us a run down of the symptoms please


From the limited info you've given its difficult to know. Though a timing chain replacemnt is NOT £6k!!!!!!!!! so no wonder they are happy to give you a 30% discount on their 600% mark up.....

Symptoms are: engine note firing; lack of responsiveness (and strange noise) when you hit the accelerator; black smoke from exhaust. It took them 'several hours of diagnostic investigation' to determine that this was the problem so this has contributed to the cost but still can't help but think I am being shafted here!

Sounds to me like they can't figure out how to solve it. So they want to sell you a whole new engine. I'd go for it with a 50% reduction and a capped off bill at £3k. Or go to an indie who will be able to rebuild it properly for a lot less! Clearly it's always a balance between convenience and cost.

I once had the same thing in 1995 at a ford dealers. They didn't have a clue how to fix an engine!

Ask to speak to the A8 Product Manager.

That should catalyse things nicely.

Has someone washed yer engine bay? sounds like water in the plug holes hehe

On a serious note, they obviously don't know whats wrong, I'm sure a well trained mechanic could have it diagnosed in time as opposed to a "lets swap bits over" technician.

So tell me this, they've spent hours doing electronic diagnosis & they've not done a simple X 8 compression test? In which case throw the bill back at them if they are claiming the heads need to come off. Feel free to give me a ring if you like 07970 642129 Declan

clapHow good is this? I introduce Ian waveyto Pistonheads and he gets a response like this, people even putting their phone numbers up!(idea Or is that 'cos you want to buy it for scrap biggrin)Not sure if its been mentioned but's it's the 4.0 TDi lump and the car was given a clean bill of health only a few weeks ago. Really hope that all your advice help toward Ian getting a good result.Well done people, keep 'em coming as my lovely Goddaughter and her action packed brother come down to see us in that car!

Ahhh Tdi - now he tells us!!!!!


In which case it could any number of things, sticky injectors wont show up on diagnostics. I also doubt it a head issue as this are uber reliable on that front.

Did they put it on the emissions test system, that'll tell you something is not right. Also these run twin AFM's dont they, if these are faulty they dont always flag up error codes from what I know.

It's a 4.0 TDi.

In all seriousness, if you warm it up properly and give it regular oil changes you want to be passing the 250k miles mark as a bare minimum before any woes are apparant.

100k is nothing for this engine.

Just giving this a heads up for the other chap who has just posted with an A8 engine problem. After some kicking and screaming and some intervention from the top, this was eventually sorted for 1400 quid.

What was the final issue? And did Audi resolve it? Did you contact Audi management?
