Blue red blue it should be on a series1, but early S2's had a blue red white, which im sure will be fine as it doesnt have the knock sensor like the series1?
Blue-Red-Blue = Series one cars (B, C, D)
Blue-Red-White = Early series two cars, with no knock sensor, mainly the first D plates
Blue-Red-Black = Series 2 cars with a knock sensor (E, F, G)
Hearts & Diamonds = 90 spec cars, with a knock sensor (G, H)
