What's good

Lighter and more economical than before.

What to watch out for

Avoid 19-inch wheels and 20-inch wheels as they cost a fortune in tyres.

16-7-2016: Problem reported with factory fitted optional extra panoramic glass sunroofs on Audi A6 Allroads. Reader had leak problem on 3 year old, send it back to the supplying independent dealer who attempted to get it fixed, but it still leaks.

15-10-2017: Report of warranty work carried out on April 2015 Audi A6 Allroad 3.0 V6 TDI: In June/July 2016, the timing chain became noisy. Strip-down and replaciment of parts took 6 weeks and apparent cost of warranty work was £1,368. Then, in September 2017, car went in for an oil service and an oil leak was found. Engine was removed, stripped down and rebuilt at an apparent cost of £5,900. The work took 6 weeks. No question of owner having to pay and courtesy cars provided on both occasions.

2-11-2017: Report of 24,000 mile 2014 Audi A6 Allroad suffering complete emissions system failure in France while towing a 1,900kg caravan. Owner had to spend €4650 to replace the DPF, EGR and Lambda sensor before it would run again. Audi UK and the supplying Audi dealer refused to offer any Customer Care Goodwill saying they are not legally required to do so.

9-11-2017: Series of catastrophes reported with 2015 Audi A6 Allroad used for high mileage. At 37,000 miles an engine noise developed which was diagnosed as a faulty camshaft. The engine was stripped and repaired under warranty and the bill was £2,000. At 77,000 miles the same noise returned and the garage has decided the timing chain tensioners need replacing. The car is now out of warranty, because of the mileage, and the repair bill for stripping the engine again is now £5,000 (why so much more?). After much complaining on my part they have offered 70% off the cost of parts which comes to a few hundred pounds. In addition the AdBlue injector needs replacing (£570) and the fuel cap release flap is faulty. (It's possible that the engine failures may be due to inadequate oil servicing under the 'longlife' regime.)

9-11-2018: Complaint of persistent squeal from brakes of 2014 Audi A6 Allroad, there since new and still there at 18,000 miles. Caused by the minure metal particles in the brake pads. Cleaning off accumulated brake dust with an airline might help.
