518i SE Alarm Buzz
Hi folks, hope someone can help me? I have a 1996 518i with a factory fitted alarm.
I don't use the car a lot as I am a white van man and work away during the week. My car has always been fine when left all week but a few weeks ago the battery was flat when I came to use the car. I jump started it and all was ok. This weekend it happened again, so I took the battery off, fully charged it and then had it checked to ensure it was good. The battery is fine and the charging is fine so I assume something is draining the battery.
The main problem is that now when I connect the battery the alarm siren is making a funny buzzing noise. Also the alarm set chirp does not sound. I assume that the alarm has its own batteries and that these are drained. I cannot stop the alarm from buzzing when I press the alarm fob. The indicators still flash and the car starts ok, and everything is working ok.
Any ideas as to what is going on?
