Yeah, i have exactly the same thing!
Its a 2001 and the engine management light is on and occasionally it stalls right after I start it when cold. If you give it a rev before it falls back to idle speed it doesn't happen.
I put it into the garage and the guy came back to me and said that it was coming back as a Heating fault on the laptop... it doesn't affect the running of the car and was gonna cost about 150 just for an electrician to have a look at it so I told him that I'd pass on the garuntee that it was purely an electrical fault and not a mechanical one.
