In more ways than one. I've always found it intensely irrtating, even though some will say that's exactly what it's supposed to be. However, it has now started going off at random while I'm driving, sometimes continuing non-stop for about five miles before stopping – then sometimes starting up again. 

 

There must be a pressure sensor under the seat (at least under the passenger seats – perhaps it assumes that if the car has started the driver must be present) and there are two thick wires under the seat, plus a thinner one attached to a connector block. Are these relevant to the seat belt alarm, and if so, which one is it and are there any dire consequences of disconnecting it? Alternatively, is there a hidden menu option somewhere to disable it?

Not one hundred % sure but IIRC it's a pressure switch. In the west,vdrivers as well. How ever as they usually default to danger the cutting the lead will cause it to default danger (open) so it will go off all the time.

There will be sensor in the seat and the seatbelt fixing.  Maybe the seatbelt one is a bit sticky ?

I found several questions about this on Google, but began to dismay at the number of replies from sanctimonious smart-Alecs who hadn't bothered to read the question properly saying simply, 'do your seatbelt up'.

 

However, I do now realise that it is probably being caused by a loose wire, so that by disconnecting it, it will be left in a 'permanently on' position. I did notice last night, with the engine still running while the car was stationary, it stopped beeping when I opened the driver's door. I think that would only be temporary though. It is actually quite a problem, because the noise certainly works by making you put your seatbelt on, but when it starts up at random when the car is being driven it is seriously distracting. I will try to get under the seat later to see if I can spot anything obvious, although it doesn't look easy to get at.

Isn't this a two part warning. There is a sensor under the seat that is there to sense an occupant. But the alarm if triggered is silenced by the inserting of the seatbelt buckle tongue in the buckle body. So I'd look there, when alarm sounds when you don't expect it wiggle the buckle and see if it stops the sound. Possible the micro switch in the buckle body is intermittent easier to change that than other parts I'd have thought.

Be assured I've tried the wiggle test, which doesn't silence it, even temporarily. I wouldn't have thought a pressure sensor would be necessary under the driver's seat, as the car can't drive itself. I'll have to take it to a Citroen service centre, but it's very inconvenient so I was hoping to avoid that. I'll report back on the outcome, for the benefit of anyone else who might have this problem in furture.

Damn – it's something that I'd have to book the car in for and leave it with them, which is incredibly inconvenient at the moment as it's 15 miles away.

I've just tried this. It didn't actually work as intended, because just after pulling away I momentarily disengaged the seatbelt and the alarm sounded, only to switch off when I pushed it back in. Perhaps it's just coincidence, but I then drove it about five miles without it coming on again. The trouble is that it's so unpredictable.

On my new C3 saloon after I had had it for 6 mths the handbrake light when it was ON would go off and was to say the least announcing. Releasing the handbrake and pulling it back on would sometimes fix it for a few days. Eventuality I took it back. The garage diagnosed the microswitch. Sometimes it stayed in the open position handbrake on but occasionally it would default to off. It was changed and it fixed it.
Try putting the belt tongue of the passenger belt in your buckle and vice versa. Drive with it like that and see what happens.

That was one of the first things I did. :D I wouldn't expect that to work because if the fault is there, it would be in the part than receives the buckle. I'll be amazed if that trick has actually fixed it, so I'll be nervously driving around waiting for it to start up again.
