It might be a bit too late now but maybe it'll help someone else. Crank shaft sensor... From about September last year I had an intermittent problem on my 1998 Megane 1.4e, the immobiliser was working fine but for some reason it just wouldn't start every time, was ok if i could bumb it down a hill. replaced battery an sparkplugs, to no avail, tried an auto electrician but he reckoned if the computer didn't show up any fault then there was little he'd be able to do without going over everything with a fine toothe comb and it would cost big time. In the end i moved house, to a flat street with little hope being able to bumb start given the number of speed bumps. anyhow got the RAC out after Id melted the starter motor tryin to get past a speed bump.. cost 50 quid to replace starer but he also showed me where the crank shaft sensor is.. looking down at my megane engine bay there's a wire (black - about the same thickness as a portable cd player power cord) its located on the right hand side of the engine - mid way down, underneath where the HT cables are all bunched together comin from the spark plugs and about the same height as the top of the starter motor. This wire appears to just enter the side of the engine and dissappear. When the RAC chap moved this wire it caused the engine to stall. I guess this problem is only intermittant because bumps etc are causing a bad connection. whenever my car doesn't start now I just flip bonnet, wiggle wire and it starts every time. I know I should just replace the sensor/wiring loom but times are hard... and now my immobilzer is on the blink...eek. I have the radio code is this the same code that overides the Immobilzer?
