    While doing some work in the MH today I could hear what sounds like a fan running, coming from the centre consul area. The sound is similar to that of a computer CPU fan.

    Strange thing is the noise only occurs when the keys are out of the ignition, put them in and light the dash board up, noise stops????

    Turn the key off and remove them, after about a minute the noise starts again.

    Could well be coming from under the bonnet, but it’s so wet at the moment inspection will have to wait.

    Does anyone know what this might be, I can book it in the local Peugeot dealers but though I would ask the question, to make sure I wasn’t doing something stupid.

    2015 X290 Boxer.

    Never noticed a fan running like that in our Peugeot, but it's a 2013. But, I have a similar noise in my car. (Citroen C5) It's a fan running in the dash. I have a built in sat nav and radio/cd with Bluetooth, phone, and all sorts of computer gubbings, it appears to be coming from the radio unit.

    That's what I thought. If it stops raining tomorrow :rofl: I'll lift the bonnet and see if more becomes evident.

    Whatever it is it's not using much electricity, cab battery is still fully charged.

    When I turn my Boxer engine off, I can still here fans or motors running somewhere in the engine and a few clicks as they turn off. When I turn the Citroen engine off, I hear 3 or 4 electric motors or fans gradually running down, (sounds like 3 or 4 muted jet engines shutting down )Takes a couple of minutes sometimes for them to stop, then just as they do, the fan behind the dash (radio) starts up. It worried me the first time I heard it, but it went off after a few minutes. It does seem to run independently of the ignition though, and could be similar to what you are hearing

    That's the one I think, but the cut off doesn't seem to be working (been running for several hours now). I'll book it in tomorrow at the dealers.

    Ah, that doesn't sound right.

    We've got a fan in the battery charger that runs when on EHU if the charger is working hard, switches itself off/on with a mind of it's own.

    Not sure where the fan noise was, but it was running 24/7 whether on EHU or not.

    I had it booked in at the local Peugeot dealer, but before going decided to give the MH a good run out. Got everything nice and warm and after 30 miles or so came home. Fan has never run again since, it now seems to have cured itself?????

    Hi @Brian_K . Did the fault with the fan running reappear? I've just noticed the exact same problem with my Fiat (2015 model)

    It sounds like a fan just behind the radio. No noise apparent from within the engine compartment.

    I've noticed that if you turn radio on and off, open either the passenger or drivers door, the fan noise stops temporarily but then comes back. We're heading up to Kilder this weekend so I'm hoping the long run up there will sort it out.

    Cheers
    Alan

    Angela's C4 makes more noise with everything switched off than when it's running! Worried the hell out of me when we first got it but used to it now.
