I'd like to say great, but the owner's handbook says that the lights should come on for 2 seconds when you turn the ignition to position 2 and then go out with the rest of the warning lights to say all is well.., unless i've read it wrong !! :(
I've just bought a TD5 GS 2001 (52000 miles landrover service history) and am a bit worried as the ACE warning lights do not come on at all. I have felt the unit - located on underside of car - it's warm after use and the fluid is at the correct level and whooshes about when the engine is on...
