I had the same query when I bought mine, checked with the dealer and it's meant not to be there to allow cooler air to pass through to the intercooler.
Sounds wrong to me, mine's virtually petrol quiet and smooth! Definitely no vibrations through drivetrain, recently changed clutch and DMF and didn't have those symptoms either.
Update, have changed the tyres to 255/35's and running them at 38psi front and rear, putting the correct size ratio tyres has made a big difference, 235/35's are just too low a profile. Much more settled a ride now, thanks for all the replies as well.
Hi guys, just had 19's fitted to my 2007 A6, 2.0 TDI SE, tyre sizes are 235/35 x 19, the dealer set them to 34 psi all round as a default setting, just seems a little bit floaty, any recommendations greatly welcomed.
