- Make sure you're turning off the electronics when you leave the car, either by hitting the Start/Stop switch a second time or by locking the doors.
- What are your drives like? Quick <15 min typical drives?
- Are you using accessories while the engine isn't running?
- You may just want to take it to the dealer to test the battery
Thanks for the replies!
Most of my journeys are indeed sub-15 min, and I don't sit in my car just using stuff, BUT I live in central London so its often on the stop-start...so maybe in that respect yes.
Really hope it starts in the morning
