hi there, my mother in law has a multipla jtd on an 04 plate. A few days ago the horn went off by its own accord, she disconected it, yesterday the alarm kept going off even when the car was unlocked i have disconected thhe battery but there is still a constant beeping noise coming from the car, any ideas?

Guinea pig in the boot?

its more of a trapped hamster in the wheel arch!!

This has to be said...


Alarm!?

Who'd nick a Multipla?

I had a mate who had the 13 inch steel wheels nicked off of his Allegro! They actually stole the car, brought it back and left it on his drive on bricks!

I own what must be 2 of the most knocked cars in history

& I thought that I had issues...

Try disconnecting the interior sensors, these are located in the overhead light console.
Carefully prise out the grey sensor panel, use a kitchen knife as I've found that screwdrivers are too narrow and can crack the plastic.
Disconnect the plug and see if this helps, I had the same problem on my old Multi and had to replace it with s/h unit.
