Alan,Audi A6 3.0 TDi

This is my fourth Audi TDi and my first A6. I opted for the 3.0Tdi Quattro SE Avant as it rides a little higher than the S-Line which helps when towing my caravan. When reading reviews the A6 was criticised for a firm ride so I had the adaptive air suspension fitted and it is superb, in comfort mode it floats along and gives a superb ride, however for a sporty ride just set it to dynamic. This is my first automatic and the tiptronic is a dream to use with apparently seamless shifting, you can over ride it at anytime with the shift paddles giving you total control. I had my 3 previous TDi's superchipped but this time I have gone for the Tunit unit which I had fitted at Tunit Chorley along with a K+N Filter. If you sell the car you can take it off in minutes and Tunit will give you a part ex allowance if it is not compatible with your new car. It now punches out 275 bhp and the power delivery is smooth and instant.
