I am changing my car in the new year so thought I would test drive an A3 2.0 TDI 170 S Line to see if it is much better than my A3 2.0 TDI 140 (remapped) sport. The tdi 170 I tested was an 06 plate with 3.5k on the clock. My initial thought of the 170 was that the engine sounded much the same as my 140, no quieter and no smoother. It certainly didnt feel as quick as my remapped 140 and revved to almost exactly the same point. The fuel consumption was also lower than I would have expected. I came away thinking its a lot more money for not much more of a car, I was disappointed. The next day I went to my BMW dealer to test a 320d M Sport, although this was not quite as quick, it was so much quieter, smoother and revved well above 4500rpm. Overall a superior engine, not to mention the handling and feel of the car. (and returned 45mpg on the test drive!!) I am now seriously considering the BMW even though its bit more expensive. Has anyone one else got any comments or feedback on the tdi 170 to help me with my decision? Did I try out a duff one?
