Hi lee & Gregers thanks for the comments, the car is in the garage at the moment, so i hope they give it a thorough check, intial thoughts it's not an issue so maybe similar to your noise. The Problem for me is it's got a limited warranty & i'd rather get it sorted if it's an actual fault, but after reading your comment & a previous comment then I am a little more happy. Last thing I want is a bill 3 months down the line when the warranty has expired. It's not getting any worse.....famous last words! so if they come back with no fault found then I will wait till the warmer weather kicks in & see if it goes......before the warranty expires!
