I have an R reg and have the older style looking Dash with the three seporate bits with the small square lights, but i have seen an earlier N reg with the the newer dash with the large rectangular DIS pannel in it.

Could it have been changed there are some cracks in the plastic so it looks like it has been removed at some point, but the millage is the same as in the service history. Which is dealer stamped and i have verified it before i bought the car buy ringing the dealer.
