Which year and model? If it is the all-air system, then it's a bit complex to give a quick explanation, but I'll wait for model details so I can check the manual first. Peter

Ok if they are unrelated that gives me some scope of where to look. First I need to check for power at the switch as it simply does nothing at th moment, no lights, no messages.

would say it was a bad earth, I had the same fault on another car when I plugged a trailer in - turned out to be faulty wiring (brake wire had worn through and was touching the chassis) on the trailer. Did exactly the same though you pressed the brake and the dash lights dimmed right down.

The cruise and the air sus do sort of have a connection as the cruise is managed by the engine management system which has inputs for speed and the air sus adjusts itself at set speeds. You need to look in RAVE to find whats connected to what.

hi bruno and welcome, scorpion racing springs to mind, but when i last tried to contact them they answered, put me on hold and forgot about me so i haven't bothered with them again, good luck, ian.

you need to see the upper inlet manafold, or compair engine numbers but I dont have that detail here Aidan

yeah i thourt so didnt think it it was goin to be worth do cheers

Can you try another engine ecu,the 3.5 flapper type ecus seem to die of old age and poor idling or hunting above idle are classic signs of this.If you can borrow another ecu just plug it in and try it.I dont see many of these now,but a few years back this was quite common - enough for me to get hold of a test ecu to keep on the shelf.Do check out the dist though,again timing scatter is a big enemy of a Rover v8 trying to idle.

Hi Jon hope you feel better soon mate, appreciated that you and the other forum members are helping me, been a mechanic for many years (mainly given up now tho) but this new electronic stuff is doing my head in. do you think that the fuse box has now made an intermittent fault in that it ran perfect and started perfect before the battery change, i wish now that i had not changed it! i will try an look at it when i get home from work tomorrow...
