Hi. My 1st post ! I have owned my 1st Audi A3 Sportback TDi E 1.9 for two yrs now, has 92k on the clock and no serious probs ...so far but I would like to upgrade to something with a bit more spec Leather seats Etc I know the power output of the twin cam 2.0 is more than the 1.9 but which engine is the most reliable and has the best longevity? I am no boy racer (well I was once, an old fart of 60 yrs old now) and the 1.9 is quick enough for me, but there seems to be more 2.0 higher spec A3s on the market so just would like to know?. Thanks in advance.
