I looked on other posts, and on my other stilo i have a metal plaque which says the colour code on it.

There in lies my problem i dont have that, pretty sure its fallen off or something, is there anywhere else i can look on the car?

Its a 3dr 1.8 grey 04 plate (if that helps)

Cheers.

Only under the bonnet I believe. Dealer should be able to tell you from chassis number also I believe though
