Hi, help please, my alarm on 1998 C2 has just starting going on for no reason that a can find at all, it started last night and went off for about a minute then would turn off, it appears to be just the alarm and the indicators don't flash and you can start the car so the immobilsier isnt being activated. In the end had the discount the battery as the neighbours didn't look happy. someone mentionned that due to lack of use ie about 2 weeks and the cold weather that the battery backup on the alarm siren had flattened, i took the car on a drive and that alarm didn't go off for 12 hours but at 2am so again neighbours not happy! do you think this is the problem or something else and if so would a trickle charger help? :(

It could be a bad ground or a bad component in the system.

I do not know where you are located but you need to find someone with a PST2. The PST2 can pinpoint problems in the alarm system within a few minutes through alarm codes and component testing. -- Otherwise you are guessing at more than 15 components that make up the alarm system. Some race or independent shops have PST2's and all dealers have them or the newer PIWIS tester.
