For anyone who comes across this common fault, here's how I fixed it:
1) Remove radio (standard keys work as good as anything);
2) No need to remove radio just drop it down onto the gear lever area but make sure you cover it first with a clean rag so not to scratch anything;
3) Place fingers beneath the Piano Black trim. The trim itself, although looks rather fragile, is backed onto a metal surround. Pull firmly toward you and in slightly upwards motion. It should detach - there are approx 2-3 clips that will detach;
4) I found it then easiest to remove the blanking switches either side of the ESP switch to be able to grip the top of the trim and detach the top clips. The blanking switches literally fall out...
5) Remove the cup holder by using a bladed screwdriver to prise up the clips above it (it will make sense when you see it). Pull it directly out toward you;
6) Remove the ESP switch but leave it connected - no need to unplug it from its connector just let it dangle carefully;
