I think ill take the wheel out and put it bolt it back on see if it make changes, is yours a GTTdi or a normal 1.9TDI
Sounds like a flat edge on one of the tyres to me... my mrs had the same thing on her motor and I was sure it was a wheel bearing - it turned out that her tyre resembled a 50 pence piece...
what tyres did they fit
Hmm sorry to hear that.. odd... They never made a noise on mine. Did you put the good tyres on the front? It might just be that the tyre thats almost bald is more noisy than the others and than your old tyres? Try putting the worn tyres on the front and see if it changes. (you should run the best tyres on the back anyway)
