I want to fit an Evo Grill. What is the part number and the procedure?

Part number is A168 888 04 60 and is at priced £27.50

The grille is easy to change - there are about 5 or 6 screws on the back to remove the grille from the bonnet. Then the badge and chrome strip are simply held on by plastic lugs which you lever to release (it's obvious when you see it). You can use kitchen knives but a flat screwdriver will do just as well and is probably safer!
The badge and strip simply push into the new grille. The badge and strip have different part numbers so are available separately. A168 888 00 09 the star and A168 888 00 21 the chrome strip. (Loff)
