I've not had a car let me down for a very long time. It happened today. I was moving at speed, heading for the C4DI Hardware Meetup when I pressed the button to start the engine and nothing happened.
So I checked all the obvious things, changed the battery in the remote and finally called the RAC man. He arrived in very good time, took one look at the car and said "I got called out to one of these a while back. Couldn't get it to work".
And so it turned out. The car is presently awaiting transporter awaiting a trip on a transporter to the garage for diagnosis and hopefully repair. The fault seems to be with the steering column lock (which is at present unlocked but might lock when we start turning the wheel).
I'd put the notes for the C4DI stuff on the web (we were playing with stepper motors, you can find the stuff here). Hopefully everyone did too.
