Anyone having issues starting their car after a short drive? I'll drive it for about 10-15 min. and it sits parked for about 1hr - 1.5 hrs, then when I go to start it, it won't start.. the thing is, if I reflash MHD stage 2 OTS (e40), the car will start no problem. Also, no errror codes when i scan for fault codes via MHD:

Charge your battery on a trickle charger and let's see what happens.

Any recent work done to the car?
How many miles?
Any errors on the nav screen like "key not detected"?

Issue has been resolved by MHD. Reflashing stage 2 e40 OTS completely resolved the hot-start issue I was having.
