Yes. Use this stuff. It is quiet a bit cheaper then Dynamat.

Apply it double layer to everything including under the bonnet. I can't guarantee it will stay real well with a V8 on the bonnet. They run quite a bit hotter then the TDi. Then get the mats they use in horse stalls. About 3/4" thick recycled rubber. Put that down in the rear tub. I also suggest trying to get the Euro rubber for the bulkhead and seat box, as it is substantially thicker then our rubber sets.
As far as results. I have had a ton of these trucks and this was the quietest I ever had on. It still isn't a Range Rover. But it is definitely quieter.

Has anyone had any success in makeing a hardtop D90 quieter inside? If so, what did you do and how hard was it? What were the end results?
