Audi A6 Avant - 3.0 TFSI or 3.0 TDI?

[Chris.B]

What's the general opinion of the previous generation Audi A6 Avant? Specifically the 2008 C6 Facelift, and ideally with the 2009 Quattro update.


Engines wise, the 3.0 TFSI (300PS, V6 Supercharged petrol - detuned version of B8 S4 I believe) looks great... but I can't find a single one on Audi Approved Used or Autotrader, and only one here on Pistonheads. Is there something wrong with them? Or did everyone just buy the diesel because BIK tax/carbons/MPGs? I don't do enough private miles to care much about fuel consumption .

So, as the petrol is in short supply, what about considering the the diesel? The 3.0 TDI (240PS V6) seems to be in plentiful supply at around £17k-£19k for a 2010 Le Mans, and a quick search reckons a remap will give another 40-50BHP. My last memory of a VAG diesel was over ten years ago with a 1.9TDI, but I'd hope with ten years of progress and two extra cylinders they would be more refined now?

Would love to be looking at the S6, but the thought of a repair bill on that Lambo V10 sadly rules it out.


And then as an over budget choice, what's the new 2011 C7 model like? Looks to have the same engines as the C6 facelift, and a quick look on Audi Approved Used shows 72 S-Line Avant's with the 3.0 TDI (240PS V6) and some people seem to have actually bought the petrol this time as there's 3 with the 3.0 TFSI (300PS, V6 Supercharged)... both starting at £29K.
But it's over the ideal budget, and is it really £10K+ better than a late C6 facelift one?

There was a thread in this section a few weeks back on someone who'd run a C6 3.0 litre petrol so might be worth going back a few pages... If you don't do much mileage I'd always go petrol.

Thanks, will have a look for that thread. But much as I'd agree with you re petrol, I can't find a single one on Audi Approved Used or Autotrader, and only one here on Pistonheads... so where are they!?

Thanks guys;
I'm still at a loss why I cant see many 3.0 TFSi (petrol) Avants at dealers. Can see plenty of TDI's
Thoughts?

Well after several months of looking and hanging on for a good nearly new one I finally collected an A6 Avant TFSI today.
Will keep you posted on how it fares.
So far, loving it; the supercharged engine is just great.

Yes, Daytona grey

Out of interest, since my experience was that finding a 3L TFSI S line was a difficult hunt, I had a look at the DVLA figures (howmanyleft.co.uk) to see how many are registered as at the end of 2013 Q3 (Q4 figures not yet available).

So for:
Audi 3L C7 TFSI s line petrol there are 66
For the Diesel 1668

Just out of interest I also looked at:
Audi RS6 C7 = 97
Audi R8 V10 convertible = 270
Aston Martin DB5 = 277

No, not the black edition; it's a fully loaded S line
