A fault has developed on my '88 900i.
It first manifested the other night when I arrived home and switched off the ignition, except the engine did not stop and the lights remained on, until I took my foot off the brake then it stopped.
On investigation I find, with the ignition off, when I depress the brake the parking brake and brake warning lights dimly illuminate before a relay clicks, then these warning lights brighten and the headlamps illuminate and possibly the fuel pump spins up.
I found a mention on a forum relating to a similar fault where earthing faults were implicated but of course I can't find the link again :-)
Anyone else had similar problems?
Cheers all
Sam
