I bought a ST TDCI Mondeo a month or so ago, and I'm having a problem with the alarm. For no reason I can see, when I lock the car, the alarm will go off, but there doesn't seem to be a pattern to it. For example, I locked the car this afternoon and the alarm kept sounding for the first 10-15 minutes, but has now been silent for around half an hour. I have done the usual check all the doors/boot/bonnet are shut but this doesn't seem to help?
The only other thing I have noticed is that it appears to be worse when the weather is colder.
Any help appreciated, as it's driving me mental!
