Problem solved

Problem solved after fitting brand new hoses. The sound when dumping air at gear change is perfekt yet again
Still have some sound when accelerating but will put it down to the Forge Diverter valve since the car pulls, feels and drives fantastic ones again Falling in love all over again

ok so i have the sqealing noise on my 57 plate cupra.

It is completely standard anf i have changed the dv to rev d model..

It started when i had the cam belt and water pump changed at my 40k service.

Could they have moved or split anything to cause this??
