Currently driving a 2015 diesel Scout and find it an excellent car for my needs. Roomy inside, well equipped, decent sized boot even before you put the seats down. Deals with mud and snow in North Yorkshire with minimal hassle. Happy to recommend it.
It replaced a 2009 Octavia 4×4 estate 1.8tsi which also had much to recommend it but I had one of the duff engines which Audi were producing at the time. Not sure about it having duff pistons, that wasn’t a story I heard at the time, but it steadily drank oil from 6 months onwards, probably half a litre a month. It also left me stationary at the side of the road when the fuel injectors went at 2 years and were replaced under warranty.
At just over 5 years and 50k the timing chain, which wasn’t supposed to ever need replacing, jumped a sprocket. It allegedly had a tensioning system in which a cog was somehow kept tensioned by the oil pressure and possibly the regular loss of oil had allowed it some free play and thus unanticipated wear. Skoda did meet some of the cost of the repair but it was still a 4 figure bill. After that its oil consumption increased dramatically, 3 litres in a good month, although it still passed its emissions check to both my and the main agent’s surprise. At their suggestion I traded it in as the next repair would have been an even more major engine rebuild.
I understand Audi did make some changes to the engine design and service schedule and a bit of research on Briskoda or elsewhere may tell you if your 2011 model is likely to be affected but if it drinks oil and hasn’t had it’s timing chain seen to I would be slightly wary.
The 2015 Scout only came as a diesel so I had no hesitation in buying one. Irrationally I would be very wary about buying an Audi although I did take a little heart from knowing that a colleague who had similar engine problems with his Audi had paid three times as much for the privilege.
