Only had my brand new car for 3 weeks.
There is an annoying buzzing noise at 1400 revs behind the driver seat under the floor.
What could this be?
A5 badge squint?
Passenger windscreen wiper rests too high?
The car has been back to the dealer but nothing has been fixed!
Badge apparently is an optical illusion.
Cannot lower the wiper as it might hit the bonnet.
Pig in a poke?

 

Problem now fixed. Manufacturers fault. Fuel pipe not clipped in behind driver seat. Had to take seat and fuel tank out to access the pipes.
