Do you have any advice on buying a diesel Volkswagen or Audi in light of the emissions scandal?

I'm considering buying a used 2.0-litre diesel (2013/2014) this year, either a Volkswagen Golf or Audi A3 Sportback (but also considering a 320d) and would like to ask whether, in the light of the Volkswagen "Dieselgate" scandal you have any buying advice/ concerns. I am concerned that any "fix" may reduce the MPG and PS of affected Volkswagen making them less desirable to run or own and having a negative impact on values.

Anything on the MQB subframe system, so every Golf, A3, Leon and Octavia has the new EA288 TDI engines that are actually among the lowest NOx in Europe and do not have the problems of the older EA189 engines. They are not, however, more economical. BMW had a problem with the timing chain tensioners in its N47 2.0 diesel engines but later versions of this engine in the E320dED were as close to the ideal of 163PS, 400Nm torque and I averaged 63mpg over 8,000 miles.

Plenty of second-hand choice, excellent cabin quality, efficient petrol and diesel engines.
Big improvements in quality and refinement over previous Leon. Great to drive with sharp handling. Good value. Shares same base as latest A3 and Golf.
More practical version of the A3 has more passenger space and a larger boot. Wide choice of engines including impressive 1.4 TFSI. Well-equipped as standard.
Saloon shape but actually a practical hatchback. Far superior interior quality than outgoing model. Very practical with a large boot. Feels solid.
