ok, i drove my v6 to work on saturday, and locked it as normal with the plip.
a few hours later, i unlocked it with the plip, and opened the boot (engine bay boot). the alarm went off, and wouldnt shut up. i could still lock and unlock the car, and even start it, but the alarm just kept going off.
i disconnected the battery but it had a backup so it carried on going. then i locked the car and let it go off. eventually it stopped. i approached the car, unlocked it with the plip again, and it was fine. no alarm, and ive done 200 miles today with no problems.
whilst the alarm was sounding, as well as the siren going off, there was a ticking noise from what i think to be the alarm under the wiper cover? it was almost like it was trying to reset but couldnt?
i can only think of water getting in and disturbing it due to heavy rain on friday. could it be anything else or has anybody had these problems?
