I drive Volks Wagon Parati 1.6L and have never found any problem with it whatsoever....
Today after a drive, when I was about to park my car in garage, the alarm system went off without any reason as soon as i turned the ignition switch off.... caused embarrassment.... unplugged the battery then re switched but nothing happened.... then opened the panel and removed the alarm system switch to shut it up.... the lock system is also not working means all the doors are kind of disconnected with the key lock at driver's side, means it doesn't matter if i open the door or lock it as the remaining three doors have been disengaged with the key.... don't know if wiring has incurred a fault or the alarm system has gone bonkers...
