Peugot 306 - Cooling fan / car runs when key removed - gavmoffat

Hi all

Had a strange one today. Drove my 306 back from work pretty fast and when I got home cooling fan remained on at full pelt for about 15 minutes after I'd stopped and switched off the ignition.

Naturally this drained the battery somewhat, but by giving the car a hefty rev alongside the ignition it did get going. I took it for a short spin to get the battery charged but when I returned I got a nasty surprise. The engine stayed running even when I turned off the ignition and removed the key! I had to manually stall it to get it to stop. Unsurprisingly the cooling fan came on again though and I expect when I return to the car the battery may well be completely gone.

There's a few possibilities that seem to come up (fan sensor, fuel cutoff solenoid, wiring) but whatever I do it'll need to go to the garage (after a jump start) as if it's wiring there's a fire risk. Any ideas if I'm on the right track with diagnosis and how much it will cost to deal with?

Sorry forgot to mention it's a 1.4 petrol

I think its normal for the fan to go on running after you have stopped if the engine is over temperature, but as for the engine not stopping, if it was a diesel I would say stop solonoid but I don't understand these new fangled petrol engines, I would suspect its an ECU problem.

There is an earthing point attached to a bolt on top of the gearbox.Make sure any cables haven't come adrift/broken away.hth
