The dealer can't find any current drain at present - other than what is supposed to be there (about 30mA).
I'd be surprised if it was the Ice>Link as I thought with the vehicle shut down, it shut down. I have - or at least had - charging set up to run only when the audio is selected to the iPod and otherwise it's off, but I may need to check it again in case it's changed when the battery was dissed in March - car was flat after we came back from 2 weeks abroad. No ipod on board at the time. The fun started after that.
Bring back simple cars with easy to fix problems.
