206 Flashing STOP light...grrrrr

I have not had my 206 W reg diesel very long and it had been fine to drive doing long/short trips. Now every so often when I am driving along at 50/60mph I suddenly hear a clicking/ticking (relays??) noise behind the dash and the STOP light starts to flash for about 10 seconds inconsistantly. Temperature is flying up to red. Within 20 secs everything calms down back to normal. This can happen any time between me doing 40 miles and 700 miles!! Have taken it to main dealer,they kept it for 3 days and didn't know what was wrong and guessed they should replace the green temp sensor & blue temp sensor but couldn't guarantee that was gonna solve it. This obviously has not worked and it's still happening every so often. I cannot afford to go to the main dealer again for a while. Would really appreciate a reply from anyone else who has had a pug like this or knows what it could be.

Not really a solution here Bex but I get the same on my 406 (stop light only though). I haven't had time to get it investigated but it seems to happen at the same time as the fan kicks in! Because it's so intermittent I'm not too worried about it but I will get it sorted before the winter months. Like I say - not really a solution but good to know this is common and therefore someone will solve the mystery, I'm sure. Sy

This is purely a guess, but could it be a faulty thermostat that is not opening until much higher than it's design temperature, i.e. at the point at which it kicks in the warning system after which, having opened, everything cools again.

Do you have aircon? On my Xantia I have just occasionally had similar symptoms which I'm fairly sure is down to a duff connection to the Bitron sensor on the thermostat housing although my temp gauge didn't rise if I remember correctly. I took the plugs off and cleaned them with alcohol and switch cleaner and it seems ok now.

Faulty earth maybe? What is this word "gonna" English? I don't think so!

Hi, not a good reply here, but it seems that the BSI is getting a "hot water" signal, because temp gauge goes up and relays click etc. Temp sensors should be ok cos they?re replaced. Poor contacts between sensor and BSI unit seem the most likely cause, or maybe the unit itself. May need some time consuming voltage measurements if you know where to look. T.

as the vehicle is semi-mux the coolant info doesn't go via the b.s.i. .... e. g green x2 way coolant sensor hard wired straight to the ecm regards mark
