Mk3 Alarm Siren Location

Where is it? It's going off randomly and the alarm itself is not triggered (no flashing lights etc) - so suspect the siren unit itself. Can't find the thing - noise suggests RHS windscreen/wing area - but can't find it.

    Ok found it - tucked right up inside the wheel arch liner. Need to remove liner fully, then you can unbolt and disconnect. 2 of the three pins have signs of corrosion (green and white deposits). So that's probably it. Going to leave it out for now - car spends most of it's time on the drive and office car park. Just might use the old crooklock occasionally now.

    Nice one for updating the thread :thumbsup:.  Too many don't and no one is any the wiser!

    Randomly my MK3.5 alarm started doing this tonight, no indicators flashing or anything. I could even drive the car with the alarm sounding and I have no idea why! ☹️

    My key fob wouldn’t deadlock the car which normally means there is a door open, there wasn’t. I opened the bonnet and closed it again, just in case and that seemed to sort it, it hasn’t been opened for days now. I locked the car up and it hasn’t done it since - very puzzling

    OK so I tried the passenger (nearside) - scraped knuckles and got the liner out - siren is not there.  Can ANYONE tell me where the alarm sounder / siren is on a Focus ESTATE Mk3  please?

    What is the problem with the Alarm and why do you need to find the sounder ?
