Default discovery 300tdi immobiliser bypass, the easy way.

through some investigation, i have found there is an easy way to bypass the disco immobiliser, wanted to share this as its a lot easier than stripping down the dash board to get to the top of the heater matrix to find the faulty box of trix.
1. if the dam car cuts out when running , but then works fine after being left turned off 5 mins. run a wire from the fuel solenoid to the ignition switch, remove the cover on the opposite side to the key and connect to the white wire. (leave the original in place)
2. if the car fails to start due to no power to the starter motor.run a wire from the starter solenoid (leave the original in place) into the footwell in the drivers side, remove the plastic acess pannel, find the starter relay, find thick brown/red wire and connect into it.

The immobiliser disables both the fuel solenoid and the starter motor. and can fail on just one or both opperations . installing these two wires gives you a reliable landrover again, till the next fault. ha ha,

I think we may just have covered that one.

I did this however My brown/red wire did not give me my 12VDC when the key is turned to cranking mode. I did find a white/red wire from the key switch to the fusable link that gave me my 12VDC. This seems to work fine and I'm back on the road again... until... well you know. Haha

I know the spider issue is well known and there are lots of tips out there to suggest ways of dealing with it but I do wonder if this thread is a step too far.. seems like offering it on a plate..

however if my car gets nicked tonight it'll save me having to fix the brakes on Saturday and the toerag what nicks it will get their comeuppance when they try and stop..

Hi Guy's novice to this so bear with me, wondering what your thoughts are with my problem could be linked to your post. Done very little investigation work yet planning it this weekend.
Driving along on Sunday night, Landy died! No dash lights on position 1 of key and nothing after....Dead! Lights still working, no indicators, no radio and no elect windows. Alarm arms and disarms and light flashes on dash, only light that comes on dash.
Checked all fuses and connections I can get to, all fine. Has now sat 2 days and still the same. Tried doing the immobilisation override procedure as there is a code written on the front of handbook, no joy and not sure if it is correct code, just 4 digit code written but no info on what it is.

Any ideas

Cheers Jim

Did you do the thing with the drivers door key to put the code in?

check the ignition switch wiring if you lose 12v live to the back of the swtch when you try to crank it over. run a fused live direct from battery to back of switch. Also check live into left hand stalk. and do same with this if necessary
