Thanks Gareth I haven't taken the wheels off yet as I didn't know the torque to refit them. Thet need to come off to be cleaned properly, the spokes and rims have been cleaned regularly but the barrels are a bit of a mess. The handbook contains a says to go to a specific page for the torque but it's not there. 110nm seems a bit low to me given the wieght of the car. Many thanks fot taking the trouble to respond
