As Colin's enjoying a life on the ocean wave, would it be worth having a look at David Poole's GEMS manual, I don't know if this issue is covered in there?
Not at the moment he isn't....Oriana cant get into the berth so delayed departure, lastest is saying maybe tonight????
Anyway, more interesting is this problem and what Andy alludes to is a different issue totally (main battery going flat as the GEMS fails to totally power down, I developed one of the work arounds for that which works, others also have different methods involving relays) This issue is one of the interaction between the GEMS and the 10AS (immobiliser). The GEMS and the 10AS share a rolling code protocol and they regularly get out of step, there is no pattern to it and I have been left sat at a petrol station for 15 minutes once. I have tried everything, removing the key, making sure the spare key (which was hidden in the car) was well away and even wrapping it with silver foil (MMC advice)nothing works. you can go days without a problem and then have 30 no starts almost in sequence, that and throttle sticking at 1500 (yet another issue) was the main reason for selling the car. I had resorted to carrying a laptop with me and I bought a £1K worth of Rovacom Lite software and access harnesses to allow me to reboot the system, I never went anywhere without it and managed to get the reboot job down to minutes but it was a total pain. I knew others with a similar aged car with no sign of a problem at all and one that went back to the factory and resulted in a dealer buy back.....go figure.
So sorry no fix, no advice as I tried everything and failed to find a cure, moving the ring aerial around the key switch does not fix it, I even removed the aerial, taped a key next to it and used a none PLIP key to unlock and drive the car and it still did it. Sorry.....
