Hi Guys,

I've got a 2011 second generation GT, which has only done 16k miles and serviced by Bentley dealer over the last 10 years..

Recently, i've noticed :

1. A continuous hissing (air leaking kind of sound) from the front engine bay whilst idle. I've read about this common issue on the forums, but given my car is a second generation and only done 16k miles, is this maybe normal? I read somewhere that from a certain year onwards, the piping is now made from metal, so i shouldn't have this issue?

2. This noise does not present itself whilst cold, and only after the vehicle warms up (maybe after the brakes, or tyres warm up)? Travelling at speeds under 20 miles per hour, occasionally i will hear the rear (seemingly from the tyres) make this 'woo woo' noise, as if something is stuck to the tyres. When you pick up speed, the noise is gone, and doesn't present itself all the time. The vehicle has done alot of road trips, and has alot of small stones stuck inside the wheel sidewalls, and im wondering if this could be something thats got stuck in between the braking components or what not..?

3. When the vehicle is in reverse, and i press on the brakes, it sometimes makes the 'clunk' noise. Not overly loud, but definitely noticeable. Again, it doesn't happen all the time, and mostly when reversing at speed.


Any suggestions, or comments will be appreciated..
