Constant buzzing noise

[Huayra182]

Hi everyone, I'm new to the forum I have a 2015 transit custom swb 125php van bought about 3 weeks ago and noticed in the first few days that there is a constant buzzing noise coming from the engine bay and twice in the last week iv gone out to go to work and the battery has been flat. I have had the van back to the dealer I bought it from twice now and all they have come up with is a faulty battery so that has been replaced and they told me that all the customs have this buzzing noise, I'm not convinced. So I was wondering has any one else come across this. Cheers.

I can hear a noise from the bonnet when I switch off and get out but I've never noticed it still going when I get back, I'll try to remember to check this evening.

Is it something to do with the alarm?

Mine does it too as does my other van (Citroen relay) so it's never bothered me

Cheers for the feed back, if it's a case that it's in them all nothing to worry about I was just concerned when the battery was being drained, I'll leave it a week and see how it goes
Thanks guys!!

Yes I hear a buzzer for a few mins when engine is turned off and then stops. I would be happy to know what it is.

Mine does it too, buzzes for a couple of mins after switching off and then stops- no idea what it is!

Old thread I know but has anyone found out what this is ?

Mine makes a continuous beep tone , I'm sure my Mk7 did also, it's not very loud but can hear it when outside the van
