Hi guys
my 3.0tdi makes a quiet rattling noise under load acceleration. seems to happen when car has been driven for at least 30 mins and pretty certain when the weather is hot. exhaust is possibly a little wobbly at the rear, maybe linked or not. any ideas? car is a 2008 a6 3.0 tdi v6 quattro tip auto lemans saloon done 143000 miles with a good service history!
