Hi all, I have a 2002 Coupe Turbo and over the last few days my alarm has started going off randomly, (both the siren and the horn). I first thought it was just the sensors in the car but both the alarm and the horn still went off when I had disabled the sensors by pressing both the interior light switches before locking up.
So after a bit of searching on here it seems the powersounder battery could be the problem, only thing is I haven't had any beeping to show that the battery is failing, also if the powersounder is starting to fail then would it make the siren and the horn go off together??
Thanks for any help as this is really winding me up now.
