I have been using semi synthetic 2T for around 6 months and 4000 miles now and am quite amazed by the difference it has made, the tick over sounds like " a well oiled machine" and very smooth. I can change up a gear sooner with none of the harshness it seemed to have before, much quieter on the road. I definitely recommend any A2 TDI owner to at least try a couple of tank fills. I pay £9 a litre from Mobil and add 150 ml to a tank. I have read that many people add any 2T but I would suggest only use the low ash standard.
I have used it in my Audi A6 1.9 130 sport for a similar period same improvements as the A2 but have an increase in mpg up to 10% and reduction in exhaust smoke when pushing it, so well pleased.
