Final update which goes back to the original reason for starting this thread...
Another week of living with the car since its return from the dealers has only confirmed that I can't ignore the 'owl' noise (which seems to be getting louder..
) or the dash/air vent rattle...
Like Deev said we really wanted to love this car but had the gut feeling it might be a lemon that we would regret keeping...
After contacting the sales manager again he's finally come up trumps and agreed to exchange our Stylance for their ex-demo 2k miles FR TFSI DSG in black with 18's, bluetooth, con pack and muddies...
A test drive in it this afternoon confirmed that we should have gone with our hearts originally and bought the FR petrol rather than the Stylance diesel...despite the mpg...
Anyway, we drove it back to the dealers, signed on the dotted line and are swapping cars next Weds...hopefully end of saga...!...
