People are scarred of big engined with lots of miles on them hence I'd hope youe were getting that one cheap, I've put over £60K on my 54 plate and so far the only problems have been coil packs and one aux rad.

bigger the engine the less stressed it is and thus higher milages will be less of an issue vs a smaller engined car - in very general terms.

That is true, but I would make sure you get a very good deal as come selling time the mileage is going to be an issue for some, even if not a valid one.

Do the usual things, check the service history, regular proper oil changes and it should be fine.

One advantage of a newer high mileage car is that is has probably spent a lot of time on a motorway which will wear the engine and other components a lot less.

Not likely that it has been a taxi so wouldnt worry about that.

Make sure you know a good VAG independant and haggle like crazy, like you dont care about the car and go for it!

Leaking auxiliary radiators and rattling cam chain seem to be the main issues. Apart from that they generally sound reliable although I haven't really had mine long enough to find out.

Mine has just passed 80k and is fine, the engine has a little rattle (un-lubed cam chain) from cold start but over the last 20k this has not got any worse.

I would check for the following as this is what mine has needed:

Coil Packs, give the car a damn good thrash on the test drive. I did and two coil packs failed and were replaced before I collected it.

Shocks, both rear shocks were knackered on mine at 65k but were replaced by Audi under warranty.

Seat motors, mine has the heated electric Recaros (not the bucket seats) and the lumbar support motors failed on both seats at 65K so make sure the seats are fully functional (these were also replaced under warranty).

Have a look at the condition of the air filter and pre filter, I think the air intake is badly located as the amount of leaves and st that end up in mine is unbelievable.

thanks for all the advice pretty much confirmed what i had thought the car is 8000 with a full audi history there isnt much receipts for other work done on the car apart from services and a leaky washer bottle.what are the symptoms of these coil packs if they a are on the way out.also i have read a few articles on very poor fuel consumption is it as bad as most people say i wont be doing a large amount of miles so not a major issue

When a coil pack goes down you won't miss it, you'll get an engine management light and all of a sudden your car will sound like an impreza, the first time it happens you'll shat yourself and think it's serious, the reality is once you know which cylinder has lost it's mojo it's a twenty quid part and takes 2 minutes, infact last time it happened I fitted a new one in the car park of my local dealers. I basically loses one cylinder and runs on seven which makes it feel all unbalanced and horrible.

coil pack and aux rads

jack the car up, stick your head under the bumper and check for dried coolant on the rads either side

coils are a PITA !!

Is it worth buying one and carrying it in the car as a spare?

Why!
In the same tone you could say may as well carry a set of plugs in the boot incase one degrades. I would assume they are/would be in dealer parts o within 1 day of ordering hardly an issue.
Failing that you could change all 8 when you buy it therefore any on the way out will be covered.

I do actually now days have a spare in my garage simply because its a PITA when they go (normally stock item at my dealers) but the problem with having one in the car is that it's not staight forward to identify which cylinder has gone down, the easy way is to plug in VAG COM which takes seconds but that would mean carrying a laptop and connector leads all the time as well which I can't be arsed with.

Can't you just unplug them one at a time, untill you find the one that make no difference? (like we used to in the old days)

Yep but with 8 to do that will take some time. Changing the spark plugs in my 5 cylinder Fiat coupe takes a good twenty mins with the multiple torox bolts holding each one in. Still simple job anyone with the correct tools could do.

Why!
Because it's a known problem and likely to go. Carrying a spark plug when they are very unlikely to go, is not the same. As for how long it would take to find the right one, if I'm in the Alps 150 miles from the nearest Audi dealer, it wouldn't really matter if it took an hour. Driving that far on 7 cylinders wouldn't do the engine much good.
