I have a slight diff noise at around 50 km/h in my TW Magna, which seems worse as the trans heats up....anyone else heard of this....a shame as the car has only 38,000 km on the clock.....syill under new car warranty though!

Not good. Thankfully you're under warranty then

No but had a noise like a humming wheel bearing at around 60kmh.

Turned out to be a tyre that someone had damaged by wheel spinning before I purchased the car. (car was a demo)

Forget the term they used but apparently fairly common for tyres that are abused.

Recently put a new set of Grid 2s on and now silent again.

Cheers

flatspot?

Might be held hand brake on to long? jack it up and have a look.
