Default Electrical nightmare & 3 Amigos

Hi
My Disco seems to have an electrical fault. I put key in ignition and turn once and all dash warning lights come on and go off as they should but when I turn headlights on full (before starting engine) the 3 Amigos light up. If I turn lights off the Amigos go off. If I turn hazard lamp on the 3 Amigos come on and if I turn hazard off; they go off. If start engine I get no Amigos and brakes all fine.

When I turn headlights on the dash seems to dim in brightness so wonder if this is an electric fuse or relay issue or speed sensor.

Any ideas?

Sounds like the fuse block under the hood by the battery has some corrosion. Normally I would say just replace it... sadly it isn't cheap.

When working with GEMS vehicles. Never try to locate a misfire by pulling plug leads off - pull the injector connector instead. Otherwise you can blow up the ECU.

Secondly never swap ECUs between vehicles to test them, because both vehicles and ECUs may stop working, and you'll have to have them all reset by a franchised LR dealer (ouch!).

Thanks for the advice. I've booked car in to Land Rover this Friday & will see what their test platform / diagnostic comes back with. Hopefully not a big job as I've had 3 this year already. (New ABS modulator, fuel pressure regulator and tyres. Can't remember what savings look like!)

Sadly going to the dealer may be part of the savings issue... find someone who works on them near you that isn't the dealer.
