The auto-adaptives is an area of memory that stores information about your driving style. Ie throttle positions, Fuelling etc etc..

Yes disconnecting the battery will clear these, but that is no bad thing..

I would advise against jump starting your vehicle from another car.. As this can cause voltage spikes that will destroy the ECU & or UCH etc..

If you use a boost charger to jump it, then turn the sidelights on before connecting the charger then start it.. This seems to help in lessening the chance of killing the onboard electronics.

As for the battery dying.. Well the heater motor does draw a fair bit or current.. But the Batteries fitted to Megane II are a known problem.. Its not unusual for them to fail after 18-24 months..
