Just went out today 15 min drive there and 15 min back. Checked on the drive when I got back and voltage on the app said 13.4V this time.
Despite that, the stop/start didn't kick in once but bout 6 months ago when I used to make the same drive it would kick in about half or three quarters of the way there or back
Edit// Also my car did this weird again for the 3rd time which I've mentioned on here before. When I reverse, stop, and put the car in neutral, the car turns the engine off and then it doesn't come back on when I press the clutch in. The screen says to turn the key to get the engine back on. Maybe related to the potentially dodgy battery messing with the stop/start?. But then why would the stop/start only work after reversing and then not restart the engine?. I'm so confused
