The wessie alarm was apparently to meet some new regulations at the time but I think,
went too quiet, mind given all the GEM issue the facelift Mk6 had when they came out that made the alarm go off randomly it was maybe a good thing!
I had a Clifford put on theMk6 much better alarm and with self closure & proximity alarm added it was a nice extra bit of protection and laziness of not needing to close the windows when parking
