Hello everyone.

So recently my 2009 fiesta has had a boot open costantly coming on and off whilst playing a frustrating alarm tone repeatedly, commonly over bumps in the road.

Then my car began to have a flat battery in the morning or after a couple hours, i put this down to maybe the light bulb in the car was coming on as it thought the boot was open, so i took out the bulb and yet again couple hours later it went dead, so therefore i had to disconnect & reconnect the battery before and after drives which is very annoying.

After taking apart the boot multiple time i finally found the microswitch inside the boot latch mechanism that was not making contact, the striker hits it but no continuity is made between the wires.

Once i fixed the fault temporarily until i got myself a new latch from the scrapyard i joined the 2 wires that operate this light on the dash at the latch itself.

All was fine till i went to start the car and it ticked over but i eventually got it to start and whilst doing this, up on the radio screen came 'airbag malfunction & brake system malfunction'?

I havrnt started it since then.

Between my last drive and this attempt at the fix the car was off maybe an hour? I find that strange for an hour and the car has its battery almost drained with still no lights on?

Anyone come across this problem?

Thanks lads

Sorry to bring up old thread, this has started happening to mine in the past week there. Not draining battery as of yet though, I've got my internal lights off. Did you ever find a solution? Brake system malfunction is appearing and boot open warning sound etc
