C3 1.4 HDi 92 temperature warning - Clanger
We've had floods hereabouts and I doubt Mrs H will have been particularly timid on her commute. We both know where the air intake is. She rang me up to say the temperature gauge (not really a gauge but a collection of yellow, orange and red lights) was showing maximum when she started the car after work. It showed cold, as it would when the car had been standing, then all the lights came on with a sound alarm. The car was clearly not overheating and there was liquid in the expansion bottle. When she got home, the gauge showed 3 lights (normal after a short run) and about a minute later showed all the lights with the alarm. It's trying to tell me something, but what?

It's a Citreon, that's what they do !
Pop it back to the Citreon dealer and have them run diagnostics on it.

Well, so much for that side-splitting response.

Pop it back to the Citreon dealer and have them run diagnostics on it.


If I wanted to take it to the dealer, I wouldn't post about it on here.



Anyone (sensible) ?

Dunno about the C3, since it's multiplexed, but on earlier cars this was often a sign that the cooling fans were playing up - the STOP and overtemp warning came on because the fans weren't running. Does it have A/C, and if so, do the fans come on when the A/C is switched on, and is there any odd behaviour from the lights then?

Is it illogical? It must be Citroen....

I've just fired the car up and hit the air-con switch. The radiator cooling fan is quiet. I think you may be onto something Richard. I'll report back when I've had a root around. Thank you.

"but I'm mainly very calm to the point of being boring" But not on 19th June 2007 evidently!

I've checked all visible connections for security and cleanliness and the fuses. Apart from some corrosion on the power feed to the rad. cooling fan, everything looks OK. The air con has stopped working and the rad. fan doesn't switch on when the air con button is pressed. The temperature sensor has been replaced (easy peasy) but the temperature gauge still lights up. It's going to the friendly dealer tomorrow.

So you are now going to do what was suggested 5 weeks ago and you got all grouchy about! Seriously, I don't think the original problem was ever going to a self-help fix!

Easy to say in hindsight! He sounds like he's fairly handy and it was worth a go fixing it himself before taking it to a dealer. He only posted asking for tips.

Well I've got over my fit of the vapours and we've got a working C3 again. The radiator cooling fan had developed an internal fault causing a short after a few seconds running. The so-called maxi-fuse feeding the fan was blown; this puts the temp. lights on. The temperature sensor replacement was a red herring; but I felt it worth the £10 gamble at the level of knowledge I had a week or two ago. The rad. fan has been replaced with a modified version; there's now a 45 amp relay strapped to a hose that wasn't there before.

My guess is that Mrs H, having been stuck in a queue waiting for traffic to clear a stretch of flooded road , tackled the deep water too quickly and while the rad. fan was running, either submerging it or otherwise causing it to fail.
