The one gripe that I've always had with my TDi has been the amount of road and engine noise transmitted in to the cabin. There's not a great deal of soundproofing on the A2, which of course has its benefits in keeping the weight down for better fuel economy. For me though, I'd happily sacrifice a little of this for a bit more comfort.
So recently I decided to soundproof the interior and have covered most of the floor, doors, wheel arches and boot with sound deadening sheets. I was sceptical as to whether this would make much difference, but wow what an improvement! Road noise has been greatly reduced and there has been a noticeable reduction in engine noise when the car’s out on the open road. But around town the litlle diesel unit still makes a hell of a racket. I think it's going to be hard to improve things with engine noise - I'm sure a lot of the noise is simply coming out through the bonnet and in through the windscreen. But as a final thing to try, I was wondering whether it would be worthwhile to do the underside of the bonnet too.
Has anyone sound-proofed the bonnet of their A2 and did it make any difference to the level of engine noise?
Any recommendations for a good sound-deadening material that is suitable for use under the bonnet?
Cheers, Neil
