I just had the front grill replace due to a bump. I got the car back from the dealer and noticed the centre piece was scratched. I contacted the dealer who informed me that the replacement grill came without the centre piece and chrome surround so they had to use the old parts. This seems quite odd as to retro fit these parts would mean removing the whole grill. Also I cannot find any details of how to order the centre piece.  Part shown in yellow on screen shot. Any help would be appreciate

I've had to do the same thing recently, passing pheasant took out whole of front plastic grill. Needed to make an insurance claim in the end as front radar sensor had been impacted too. However as far as I'm aware the replacement grill was a one complete piece including chrome surround, and you can find similar things an eBay new for around £85
