Hello all

I have a BMW which suddenly started flashing its hazard lights while parked at night and I have to disconnect the battery to end it?

I reconnected the battery in the morning and the hazard lights had stopped although I need to press the switch several times before stops the lights?

I dont have any king of alarm fitted apart from the manufacturer's power cutoff system.

Now I am just wondering whether it is a switch, control unit, electrical problem???

Anyone can advise or suggest anything?

Many thanks

Depending on what type of hazard system is on it, it might be a stuck relay or switch. Best get a wiring diagram on the circuit and start from there.

hi.
i had the same problem in my merc when i got it. change the battery that will sort it out.

It's Probably Part Of Your Alarm System.
