    Speedo on the fritz!

    Got a bit of a random problem on my 2003 1.6 8v Astra. After driving it for around 20mins, I go to stop at a junction or pull up at traffic lights and when I go to pull away the speedo won't start working till I do over 20mph. I took it back to the dealers and that plugged the laptop on and they couldn't find any faults. Then it was ok till today. I went to Swindon this morning and on the way home I was coming down the M4 doing 60mph and the speedo just went to 0 and then worked again. When I got back into town I pulled up at a mini roundabout and the engine just cut out. It started again ok, then I pulled up about 10miles later and the engine cut out again so I went to start it and it just would not stay running. I had to keep it at 1500rpm then it was fine all the way home. Any help or info would great. Thanks for looking.

    According to my wiring diagrams the '03 1.6 uses a speed sensor (abs sensor) on the front left hub, feeding a pulse to the speed converter module, which in turn feeds the speedo.
