Just bought a 51 plate Octavia Estate L+R. 1.8T with 90kmiles.
After driving for 10 minutes it seems to exhibit a resonant whining noise which is evident above 50 mph, and at constant speed, ( worse on smooth road surfaces).
It is evident on the overrun and slowing down,even below 40 mph, but not on acceleration.
It occurs in gear out of gear and with clutch depressed and not depressed.
There is sometimes a very slight vibration felt in the gear lever during this whining.
I have cleaned up the front brakes, discs and pads, no change.
I have swapped the front and back wheels around, no change.
I have given all the wheel bearings the Mot test ! No apparent play present.
I have scoured the forums for help with the problem but no one seems to have the same symptoms. The gearchange is smooth and the car goes well.
I am thinking ..wheel bearings can be bad but not show it when you check the wheels.
gearbox oil could be low and need a change.
There might be an expensive problem within the gearbox or diff!
Any help or advice gratefully received!!
