This Audi A6 model received a facelift in 2001 for both sedan and Avant versions. The revised A6 sedan featured a new grille design and different headlights, while also being fitted with a wide range of petrol and diesel engine configurations. Most of these powerplants received a boost in power outputs.
A friend of mine called me on his 2002 Audi A6 2.7 twin turbo. He had to put a engine in it and now every time he starts it its shutting down the fuel.
