Grrrrrr! (Citroen warning light puzzle)

When did technical information about ones car become arcane "dealer only" knowledge?

Until a couple of years ago I used to be able to phone up Citroen UK for information but now they only "interface" with fecking dealers, not owners. Given that I've fallen out with my local dealer it makes it a real PITA trying to get any info about my car.

FWIW, my problem is one that can probably be solved within seconds once it's linked up to their diagnostic computer but given how dim the service manager is, (who thankfully won't actually lay hands on my car) I've lost faith with the whole garage and I'd rather have an idea what the prolem might be

*before* I leave my car to their mercies.

The problem? Citroen Synergie, 2.0 HDiSX, flashing temperature warning light that stops flashing when the climate control is either off or idle. It's not overheating. According to the handbook, if it overheats the light should not flash but stay on and the STOP light should illuminate.

I suspect the light is doing double duty as a warning light for the aircon system pressure or something like that but it's not listed in the handbook.

Any suggestions?

You really need to be hooked upto the OBDII socket to monitor live data, drive the actuators, and do some more exploratory work, but at a guess you have a cooling fan issue-possibly the low speed .

(reasoning- with the a/c compressor engaged the ECU in most recent cars calls for a slow fan to keep the condensor cool- and I would suspect its finding the fan isnt starting.)

Its not overheating because when coolant temp rises sufficiently the ECU is calling for full fan speed, which is working

Cheers Tim, that sounds plausible. I know it doesn't make any difference but I hate putting my car into the garage without having some idea of what's wrong first.

Try talking to Peugeot or Fiat, or their dealers - or a half-decent Citroen specialist. A Synergie is the same as an 806 is the same as a Ulysse.

Not as far as the diagnostics are concerned (at least according to my local Peugeot dealer).

Your Peugeot dealer's talking crap. He can *certainly* diagnose it. I very much doubt that Fiat fitted different engine management, since all three (plus the Lancia we didn't get) were all built in the same factory.

seems to suggest the same engine management, too.

Alternatively

Either way, it doesn't exactly inspire me with confidence in the Citroen

*or* Peugeot dealers.

Hmm... might get that. To be honest though, I think I'll just keep my fingers crossed and never buy Citroen again.

Thanks for the info.

But you haven't this time. You've got a Fiat.

The main agents do seem to be idiots IME. Find a local specialist or two and try them out. I've found one bloke in Gloucester who's worth his weight in gold.

That aside I had a similar problem on two occasions with my Xantia, except the warning light came on and stayed on for a while together with the cooling fans. Again like you the engine wasn't overheating and I had the AC on. In the Xantia the AC and fans are controlled by what they call a Bitron sensor. God knows what it is, but it could be worth (if yours is similar of course) checking the connections to it. I pulled the plug off the sensor and reseated it and all has been fine for the last 9 months.

i have an x reg citroen synergie with exactly the same problem. I had the air con gas topped up but the light still flashes. I know its not overheating but the light still worries me. I also have the windscreen wipers coming on when ever they like, usually when i start the car, they do maybe 20 wipes then stop but sometimes start again for another cycle...and another... its driving me nuts!!!!!

sent it in once to dealer garage but they couldnt find a fault with the wipers. My usual maintenence man cant help cos its electrical and i know if i take to a dealer they will charge me an arm and a leg love my car but its become a PITA.

any help apreciated
