Does the latest 1.6 diesel engine in the Audi A3 and VW Golf have a belts or chain cam? It seems to me that aside from the risk of a belt failure, the fuel savings over a 3-year period are negated by the cost of a belt change when compared with the frugal 1.4 petrol engine.

Belt. I popped a bonnet to check. The chain cam 1.4TSI is a much better engine. One reader reported just 44mpg from the 1.6 diesel in an Ibiza. which negates the point of it

Good choice of engines. Some petrol engines now chain cam. Comfortable and well built interior. cheap to run 1.6 TDI. Feels very refined especially on the motorway.
Comfortable and quiet on the move, enjoyable to drive. Nicely trimmed with great attention to detail. 1.4 TSI sweeter to drive than a diesel.
