Last night I woke up at 0130h with horrendous acid reflux and a full bladder. On staggering out to the toilet I noticed that the security light covering my driveway was on, and the little red LED by the lock pin on the driver's side was flashing at least every second - in the past I swear it only used to flash every 3-4 seconds. I threw on some jeans and went outside to have a look, but no-one was about and the car seemed fine. Am I being paranoid, or could someone have had a pop at it? It's a Mk4 Golf, 1.6 but bottom of the range (no air-con, no remote for the central locking, and I believe it's only got an immobiliser rather than a full factory alarm system). I'm about to go Googling for info on the red light... with SafeSearch on, obviously... but in the mean time I thought I'd put it out to the crowd for any extra input. The light is still flashing every second when it's locked, and I'm still convinced it should be flashing a lot slower. Is this normal? Am I going mad?
