Thank you for the replies. As it turns out I had asked the supplier to fit the urban cooling pack. I was unaware that it included the shield. I agree with all the great advice about claimed upgrade. I've bought allon whites ex demo that had the upgrades done to their 2012 car. By chance I had driven it back in 2012 whilst my 4/4 was being serviced and then again 3 months ago when further work was being carried out on my 4/4. It certainly drove differently more recently.
