As the online and published information about the alarm and security system is scant to say the least, I am wondering if anyone has come across this problem. It's a 2016 transit jumbo with 2.2 tdci engine. It has a siemens VDO tacho fitted.
I have had the van laid up a fair amount during conversion to a camper. The auxiliary battery has almost gone flat to the point of the remotes not working a couple of times. A drive out or idling for an hour has recharged it . The van has recently started giving a short blast of the alarm when ever I unlock it on the fob and full alarm if I use the key. This stops the first time after a drive or idle to charge the aux battery, but the next opening gives the same again. I presume this is some sort of alert but no Ford dealer has been able to shed any light on it.
Has anyone else come across this problem please ?
