Just dropped my Astra in for it's 3rd service and it's 1st MOT. I've been very unwell for the last 2 days and haven't been able to do anything to the car except change the lightbulbs back to my old 65w ones. Got up today, feel sick as a dog, drove it to the dealers and as I'd already told them when I'd booked it I reminded them that the car wasn't to be roadtested as the Blackjax system wouldn't allow them to drive it more than 200-300yards before it stopped the engine, locked the doors and sounded the alarm. No problem say the dealer. Oh and DON'T ring me till at least 3pm as I'm going back to bed after explaining I wasn't well. Got home, just dozing off and the phone rings. "Er your alarms playing up mate and it's stopped the engine and everything and we can't get near it before it goes off again" I asked him if he'd drove it and he admits eventually that he'd drove it "a bit" I then had to tell the mechanic my private access code to deactivate the alarm as even with the remote it won't stop. Now I've got to change the code, not something I'm looking forward to as it's very complicated. Just rang them back up to complain to the manager about them driving the car enough to set the Blackjax system off and of course I get a total denial about them doing it, seems they only drove it from the car park to the garage, a distance of 10yds at the most and it's my fault for not deactivating the alarm beforehand. Needless to say this dealer won't be getting any repeat business form me next year.
