Have just got an s4 grill but was wanting advice on how to fit it before I go and break something. Assume old one unclips somehow? But how does it clear the bonnet release handle? A step by step guide to switching grills would be perfect and pics would get you on my christmas card list!!! Also I like my current quattro badge, can that be fitted to an s4 grill, would feel a fraud using an s4 badge and am proud of my quattro status! many thanks in advance.
