New to forum. Name reflects intended purchase.

My low mile and well maintained 2003 A6 3.0L Quattro was totalled two weeks ago. We bought it off lease in 2006 and loved the car.

I intend on buying a low mile 2006 A6 4.2L Quattro automatic that is on a dealer lot and advertised online. Are there any issues with this year and engine that I need to check or consider before completing the purchase? It seems to have good maintenance documentation.

Regards
