My car was in at the Dealers recently and I printed off the PH Article to show the Customer Service advisers and technicians when I checked the car in. Needless to say I got the 'We're unaware of any situation regarding this type of theft' but I doubt they can use that excuse now. My OBD was already moved so I had to inform them where it was and to be honest, they were very cool about me moving it.
I'll be in touch with them as soon as possible now, but really reading the above posts, I doubt there's much point really. Half hoping they'll contact me first to invite me in...chance would be a fine thing.
