Hey thanks for the reply sorry for late response been very busy! Yeah this noise did disappear but now driving even after 20 minutes there's still a noise from a squeaky belt, (as said previously) has got progressively worse since the weather temp has dropped. Will pay more attention to it when I leave work tonight. Thinking of just replacing the little niggly bits for piece of mind soon as new year hits I.e fan belt, water pump and belt.
