Check fuse from uch. Check the hazard buton or driver window if is electrical. If don't work is uch

engine is turning crank signal ok in live data immo is programmed but next window is showing immo wrong signal.

normally when immo light not coming on, fault is in wiring under bonnet

where you think? fuse box or some other location?

Try wiring behind nearside head light (take headlight out) you will have to peel back the tape, its quite common for the wiring to rot and go green, also try wiring across the gearbox as you can lose a live there, its quite a big wire aswell, there also the fuel gauge wiring there, but first of all take out UCH and open it up and see if it got water/fluid ingress etc..
Im assuming youve checked all the fuses
P.S. if your taking UCH out your best off drilling the pot rivet out so that you can remove the bracket as you have to break the plug slightly to get it out if you dont remove the bracket first
