Car Forum / Peugeot Cars / January 2007"Air Bag" light, Temp. Gauge + Turbine noise???
I am a member of CPUK no.2482 and I own a Peugeot 405 Estate 1.9D XLD 1996 Turbo. I have been posting my queries on the official forum because I did not know that this one existed! Anyway this is the problem: Recently as I drive my "Air Bag" light comes on, the Temp. gauge stops working and now there is a strange turbine like sound under the bonnet that subsides gradually after switch off. The fuse a 5 amp. in section 5 in the inside fuse box blows but not every time! The fault corrected itself once? This time I have driven a couple of hundred miles before it happened again, any ideas? Regards, Peter. > I am a member of CPUK no.2482 and I own a Peugeot 405 Estate 1.9D GLX > 1996 Turbo. [quoted text clipped - 15 lines] > > Regards, Peter. Addendum: The fan noise is precisely that, the cooling fans are at full throttle all the time! I have checked through all the fuses both in-car and under bonnet and they are OK. > > I am a member of CPUK no.2482 and I own a Peugeot 405 Estate 1.9D GLX > > 1996 Turbo.

Not sure that the air bag light and other things are connected. If you have seat belt pretensioners on that model then the connectors for them under the front seats are often not too good. Unclip them and reclip with the ignition OFF. By cooling fans, I understand the fans in front of the rad. If you have air con on this model, then there is a Bitron control unit, usually a brown box just behind the nearside headlight with a multi connector. Unplug this, spray with WD40 and replug. This cured the fans always on on my slightly earlier 405. The temp guage is also part of the Bitron circuit. > Not sure that the air bag light and other things are connected.

Brian, thankyou for your response, I was beginning to panic, visions of flat batteries etc! Pretensioners are not fitted, but I suspect something is amiss under the steering wheel cover because I had a battle replacing the instrument cluster some weeks ago, speedo drive wouldnt locate! As for the fans I will tackle the ideas when I have time off work, hopefully the Bitron unit is the cause! It will be a relief, it sounds as if I am clear for take off at traffic lights! Thankyou again, I will repotrt back in due course. Regards, Peter. Brian, took your advice, no difference! Cooling fans still roaring away at full blast! Any more ideas, I am willing to try anything as long as it doesn't cost anything? Regards, Peter. > Brian, took your advice, no difference! > [quoted text clipped - 4 lines] > > Regards, Peter. I'm afraid I can't help much more. Certainly whenever the air con is turned on the cooling fans will run, that's the way they designed it. Whether a faulty temp sensor could cause this, I don't know. > I'm afraid I can't help much more. > Certainly whenever the air con is turned on the cooling fans will run, > that's the way they designed it. > Whether a faulty temp sensor could cause this, I don't know. Brian, I think we are at odds here. By the cooling fans I am referring to the radiator fans. The "Air Conditioning" is never used because it needs re-gassing and I am not prepared to pay for the service, I look upon it as a luxury that is not required anyway! If I am too hot I open a window, most times the window is open anyway, even in the winter! Regards, Peter Certainly if you remove the plug from the brown thermostat sensor, this is the one controlling the bitrol unit, both fans will run at full speed. Try cleaning the contacts on this thermostat and its plug.

Lost for ideas! Peter. Follow up: I have replaced the water temperature sender, removed, cleaned, sprayed with WD40 the 2 other sender connectors on the cylinder head around the fuel filter. (What a pain to get to the one behind the filter housing!) Result: still the same, cooling fans going full blast! Anyone any more ideas?
