It depends on what markings the springs have on them, and the PR code (which can be got from the inside of the service book, boot floor).
Cheers, the markings are 1 white & 1 yellow
The suspension PR codes are:
1JA = Rear shock absorption, basic design 1
L13 = Suspension range 13 installation control only, no requirement forecast
0YB = Weight range 2 installation control only, no requirement forecast
So they are 1K0 511 115 BD
