Is there anything non-destructive I can do to shush it? I think it's a 320d. Sounds like a constant single loud beebping, starts and stops every so often.
Could a door/boot be open? Try them all then close it for them if so. Problem should be solved.
We tried that, cheers. I've read that sometimes the e46 thinks a bonnet sensor/switch fails and tells the car it's being broekn into, but I can't get the bonnet open.
That's the utterly pathetic excuse of an Alarm in the E46.. as others have said, bonnet switch needs ripped out and binned - problem should then be solved!
