I think he is meaning, with the E70 if it has comfort access you don't have to insert your key to start. Then if you walk away with the key in your pocket, with the car shut down or keep running?

I haven't tried this on my 2013 E70 that does have comfort access, but if I do I will report back. Personally, simplest resolution is for the OP to simply start the car with comfort access. Get out with the key and walk away. If it doesn't shut off in 100 feet, it probably won't. But either way, OP will have their answer.

By the way Q - just noticed you sold your E38! Damn, thought you and Big E were going to stick it out with me. LOL I now have to wonder if Mwong from RF and bboard still has his too?
