Mines an import and has no alarm either. I tested it by getting in the car, locking it, waiting a minute then opened the door. I think that's right! It does tell you in the owners handbook how to test.
I'm insured with Admiral & their website only asks for an immobiliser and or tracker, no mention of alarm.
Eddie, how did you know it came from Norway? Could you check my car as I'm not 100% sure the I trust the VW dealer Ibought mine from, they didn't know it was an import until I pointed out the differences to them!
EDIT: Just realised you based that upon the town name! Is there a way to find out where the car came from as I don't have proof where mine came from. Dealer says it was shipped direct from Germany to UK, vague!
