1992 525i sport auto, M50 engine (with over 225,000mls still a dream)
I had a intermittent overheating prob(once or twice every couple of months)
but as soon as I put the heating controls on it went straight down to normal temp
also the display often came on 'coolant level'; eventually the rad burst, so I replaced the rad, thermostat & coolant sensor but 'coolant level' keeps coming up on the display, any ideas?
(the 2 wires to the sensor broke off, but I was told that they could be connected either way round?)
