Only one: an annoying "tick" noise from behind the dash board.
Excellent fit and finish, friends think it is an Audi A6!
Performance is similar the BMW 540i I had a while back, a great car to drive and push hard. The Porsche Tiptronic transmission is great for those of us who hate slush box autos, but sit in traffic.
Interior is top quality, much better than my Mercedes! The high up seats give the car an edge over my friends' Hondas.
Safety is also a huge positive (it was the reason I bought the car) with 8 airbags and 5 star ratings, it puts American auto makers to shame (the much acclaimed Ford Taurus only got 3 stars in the side test).
There must have been something seriously wrong with the 540i you had if this 1.8T Passat matches it! Either that or the Passat has had its power output doubled.
The 1.8T Passat is a lively car I know, but the 540i is a quick one. Beats the VW to 60 by about 3 seconds!
