    Hi chaps, I have a 2002 A4 saloon, in the last week the alarm has started sounding unexpectedly, though the indicator lights aren't flashing at the same time. Reading other threads on this forum it could be a the internal battery. I just want to know, is it possible to use the car with the alarm disconnected, or does the cars ECU need to have a reading from the alarm unit. I have a 2002 Passat that I had to remove the siren from and continue to use without issue ! Tia

    I thought that the plan was to open up the siren housing, check the battery type/size, buy new battery - well check its voltage first in case the problem lies elsewhere, then get a new battery if necessary buy a new battery box if no suitable sized battery can be found.

    2002 Passat giving alarm problems, hum, I have not heard of any complaints coming from the guy that bought my 2000 Passat 5 years ago - and if it was an issue I would have been told about it!

    Now where is Maplin when you need them?
