Hi guys,

Car model is 2006 A4 B7 1.8T, automatic.

This has happened a couple days ago and I would like to know if it is a known problem with the car.

Driving home I noticed that when I started to accelerate at low gears ( peak hour traffic) there was a strange noise (buzzing/winding) coming from somewhere in the engine/gearbox. To be honest I don't know if it was happening at higher gears as I started to drive like a granny when it started happening.

This has happened to me a total of 3 times since I had the car and each time was during rather hot weather after driving for an extend period of time.

The only thing I can think of is that during hot weather something in the gearbox/engine expands enough to start rubbing against something else when accelerating. Noise seems to go away when off the throttle.

Has anyone experienced anything similar.. should I be worried?

Cheers,
Adam

Forgot to mention that the problem seems to go away when I leave the car alone overnight.... to cool down perhaps.
