Hi Folks,
I have a 5 year old Touran 2.0 TDi DSG with 126k covered. I have owned the car from new.
I have recently noticed what I thought was tyre or bearing noise coming from the rear. My father (an ex mechanic) was sat in the back and noticed it first. On Sunday I swapped the wheels back to front on the same sides and the noise has changed dramatically so that it now appear to come from the front. I thought maybe it was a tyre problem and so substituted each front wheel in turn with the spare and had a test drive, the noise continued.
The noise seem to change slightly/get louder when braking. It's a rumble at speeds above 50mph but speed related and audible as a dull "whoof" noise at low speed.
I have spun/shaken both rear wheels in the air and there was no play although I can hear a mild even grating noise on both sides from the pads/discs. The discs are unmarked and the pads (the originals) are about
75% worn. I cannot hear bearing noise and both rear wheels sound identical.I cannot easily spin the front wheels (I due presume due to it being a DSG?) but there is no discernible play. The pads and discs are also the originals with about 60% wear on the NS and 75% wear on the offside.
Tyres on the rear now are Dunlop SP Fast Response at about 3mm, tyres now on the front are Goodyear Efficient Grip at about 4mm+
Before I head for the (friendly but expensive!) main dealer, any thoughts as to anything obvious I've missed please?
Thanks.
