Audi A6 Allroad (2006 – 2012) Review

Audi A6 Allroad (2006 – 2012) At A Glance


+Very comfortable to drive on tarmac or off-road. Classy image and styling. Height adjustable air suspension. Large boot. Ideal for towing. Best on Pirelli Scorpion STRs for the road.

-Doesn't handle quite as well as A6 quattro on which it is based.

Insurance Groups are between 32–39
On average it achieves 92% of the official MPG figure

The second generation Audi A6 Allroad of 2006 is half way between a normal estate and a full-blown 4x4, making it the ideal car if you need the extra traction of four-wheel drive, but don't want the bulk usually associated with off-roaders. The A6 Allroad comes with Audi's quattro four-wheel drive system as standard, as well as height adjustable air suspension, so it's perfect for towing trailers or caravans across wet fields.

It's based on the Audi A6 Avant (and only comes as an estate) so it's very practical with plenty of rear legroom and a huge boot. It's great on the motorway where it effortless soaks up miles of road with minimal fuss thanks to a forgiving ride and low noise levels.

Of course there is a trade off for this and the A6 Allroad doesn't handle quite as well as the standard A6 and feels noticeable softer in corners, but the extra ground clearance and four-wheel drive makes it superb in snowy and icy conditions where a standard car would struggle.

It comes with Audi's larger engines, but it's the TDI diesels which make the most sense thanks to more reasonable running costs. The 2.7 TDI with the Multitronic gearbox is especially smooth while the 3.0 TDI offers a bit more punch. As with all Audi cars, the A6 Allroad has a superbly built and high-class interior, while a long list of optional extras gives you the chance to personalise your car - at a cost of course.

What would you recommend doing to keep my diesel Audi A6 Allroad well maintained?
"I own a 2011 Audi A6 Allroad 3.0 TDI 240PS 6 speed auto with paddle shifts (98,000 miles). Other than 10,000 mile oil changes, what would you recommend doing to keep this on the road for a few years? It has had full Audi service from new. Is this the troubled gearbox I've read bad reports on? I sold my 2009 Audi A4 2.0 TDI 8 speed at 210,000 miles and am looking for similar again. I cover around 35,000 miles a year. "
This will have a proper, reliable torque converter transmission, but the quattro Haldax clutch does require maintenance with regular fluid and filter changes. You might run into trouble due to a build up of ash in the diesel particulate filters, but other readers have successfully had them cleaned out by the Ceramex process at £350 a time. Vital to maintain the tyres so they are all the same type and have similar tread wear. Any significant disparity can confuse the electronics controlling the quattro system.

Which used, all-wheel drive estate?
"I am looking to change my beautiful 15 year old Audi A6 Quattro S Line. She runs beautifully, original engine, gearbox, clutch, almost no faults. But I need to do significant motorway distances on the continent and UK. However the degree of luxury offered has spoiled me. I also plan to live at least part of the year in the Italian Alps where I do a lot of trekking so need a car that has a better offroad capability. I am past 67 and enjoy arriving fresh and relaxed after a ten hour drive. I have looked at older (six-year-old) Subaru Outbacks - fine, safe and reliable but lacks the degree of extra luxury. I drove a Mercedes-Benz CL500, not AWD of course but has all, the luxury to keep me relaxed as I drive. I've looked at most of the other Japanese and Korean cars, none really set me on fire! Can you please point me in the most sensible direction? I have £7000 to spend"
4WD pretty much forces you into a later A6 or Allroad because there isn't anything else in the UK apart from a Legacy or Outback.

Can I transfer my warranty?
"I bought a 2009 Q5 in August 2012, and took out a Platinum two-year contract with Warranties 2000. Have changed the car in the last 10 days - to an Audi Allroad (2009). Before I did the deal, I asked Warranty 2000 if I could transfer the warranty to the new car as it was only three months' old. Was told they would send me a transfer form, so I did the deal. Got nothing, so phoned again and was told they don't send transfer forms out, but I was to write in and give then details of the new car so they could submit the request to the underwriters. Did that and got no reply, so phoned again and was told that I could not transfer the warranty to the new car. Can you advise what to do as I have been led up the garden path by this company. I want to either transfer the warranty or get a pro-rata re-payment."
Depends on the terms of the warranty. If it's for the car and transferable to the next owner, then it has gone with the car. If it's for the car and non transferable then it's gone. Check the terms. If you think they are unfair and if this is an insured warranty then you can take the matter up with the Financial Services Ombudsman. If it's a self-insured warranty then all you could do is use

Audi A6 Allroad - Best way to sell
"I bought my Audi A6 Allroad 3.0TDI (Tiptronic) new in October 2006. It now has covered 83,700 miles, has a new MoT, and full Audi main dealer service history. I have been offered £9250 as a trade-in for a new Honda CRV by my local Honda Dealership. British Car Auctions suggests I set a reserve between £9800 and £10,600 if selling through them. I live in Fareham and my nearest centre is Blackbushe. It is the time of year when 4x4 vehicles might sell more readily, so what would you do. (I have family near Nottingham so could use the BCA centre there if there was a chance of getting a better price up there). "
I'd try at BCA, and hope for snow...
