Told today my 2001 4 motion 2.8 V6 estate is to be written off after someone ran a Red light into the side of it. (no problem there, his insurance company are paying in full).

So I need to replace it, they are rare to say the least so will look at similar age A6 quattro's, I could get the 2.8 again and essentially have the same car again. However should I look an.other engine options 4.2 V8 sounds ok? I don't care about economy, but reliability is very important. Suggestions?

Get the V8. Do it! They are not very different in design to the V6s so any problems you get with the V8 you get with the V6, that being of course the oil leaks. My 2.4 V6 pisses oil all over the place.

Yes my 2.8 V6 pissed oil. So the other size V's all leak then?

Are any of the diesels worth bothering with? I worry about turbos dieing..

I had the 1.9TDI in an A4, was a pretty good engine, nice amount of power and could go for absolute miles on a tank but much prefer the V6. Never had a problem with the turbo but only had it for 2 years and it was quite low mileage.

Avoid the 2.5 TDI at that age, some of them (although I think not all) have a massive problem with the cam lobes wearing, involves 4 new cams, very expensive.

All the V6 & V8 engines are pretty much the same design, they all have the cam chain tensioner for the variable valve timing, the gaskets under these are the usual source of leaks. Also the camshaft seals and rocker cover gaskets are another common place for leaks to occur.

As good as my 2.7T A6 is, I wish I'd bought the V8.

Go for it.

Not the A6 but we do have a 99 A4 2.5 TDI Avant Quattro... check my profile to get a feeling of running costs.

What about the 2.7T Audi Allroad?

Bit of a better looking brut for the money?

I wanted an A6 V8 so got one and haven't regretted it...... I think they're slightly cheaper than others due to the anti "Big Engine" lobby...... but I'm sure someone will come along in a minute and prove me wrong..

What about a 3.0 quattro (SE or Sport)? 225hp gives it reasonable performance with reasonable fuel economy. I had a 2002 model which I ran for 2 years without any real issues.

I've never driven it but I have heard that if the turbos go, the whole engine has to come out to replace them yikes

Hmm, maybe I'm lucky my A4 has the older 2.6 rather than the new 2.4 or 2.8, then!

For you, though.. A lot of people talk about a vast list of possible faults with the 2.7 biturbo engine, it causes S4 owners plenty of gyp and is known to occasionally fancy one of its turbos for lunch. The 4.2 V8 is a much more proven engine, and, well..

I said 4.2 V8, didn't I?

Where's the question gone? driving

There's hardly any vibration at all, it's smooth all the way to the red line. There's hardly any proper engine sound below 4000rpm as the whoosh of turbos drowns it out. It's not an unpleasant sound, but it ain't a V8.

There a little turbo lag noticeable below 1500rpm but the auto box on my car seems to smother the effect out so it never becomes a problem.

Throttle response is a bit too sharp for my liking at medium and higher revs, it can feel more jerky than you'd expect from a 'luxury' car. Even though it's tuned for more torque and lower power than the 2.7T S4 it still performs well at high revs, although I rarely feel the need to go above 5000rpm.

The main downside is interstellar gearing - for example 85mph in 2nd, so it doesn't feel as fast as it could. I guess the V8 might be the same.

I've heard the same, but I don't think it's common for this to happen to an unmodified car that has been serviced to schedule. Given the age of the car there are plenty of things that could go pop and cost well over a £1000 to fix.

TBH i thought my A4 3.0 was a bit on the slow side, and not very economical at all, low 20's average, mostly on motorways too.

Might have been something wrong with mine though, you're not the first person i've heard saying economy is decent from them, circa 30mpg?
You're wasn't an auto was it? My 6 speed A6 averaged 26/27mpg If I recall but only got into the 30's on a decent run. TBH I'd come from a 4.0 Jeep Cherokee so it's all relative I guess.

As it happens there is a 2.7T local to me within a few £100 of the insurance payout so i'm going to take a look tomorrow assuming thats ok with the seller. The 4.2 V8 does appeal more for simplicitys sake and there is one of those local to me, lower miles, year younger but I'd have to add a couple of thousand on top..

and fate is directing me to the V8 as the 2.7T seller has withdrawn the car from sale.

and ended up with an A6 2.7T Quattro Avant, picked it up today smile

The 4.2 I wanted turned out to have had recent iffy history, MOT fail -> layed up for 6 months and lost over 30,000 miles before reappearing.
