It doesn't have two batteries - that was an older design. They now use a capacitor system to smooth the electrics while the car auto restarts

Are you sure it's not weather related? Where are you based? When it gets cold and engine is still heating up, or the cabin is still warming, it doesn't tend to activate

Otherwise I wonder if they bled your brakes correctly as it sounds like the brake pedal doesn't think it's being pressed hard enough?

 

I've found that the climate control plays a big part. When my AC is on, it doesn't shut off the engine to keep the AC running. If I have it on low, it will shut off. I've also become a master of controlling to the brake to determine if the engine shuts off or not. The auto-shutoff is growing on me, I kind of like it at long intersections.

 

 

I unplugged this connector on the Negative battery terminal and now the Auto Stop/Start no longer activates on starting the engine. I'll post any other changes I notice, if any.

 

I actually don’t mind it but on my 2014 sport it activates too quickly I can’t even stop and select reverse to park in my drive without the engine cutting out ? It seems to activate immediately could do with 5 seconds or so anyone else have the same issue

 

Any long term updates on disconnecting the plug on negative battery terminal? Thanks in advance.

 

No problems at all. I've had it disconnected for one year now. Everything works perfectly.

Living in a smaller city with very little traffic, the fuel savings would be insignificant relative to the wear and tear of constant stopping and restarting the engine.

 

No problems here. Disconnected a long time ago. I always plug it back in before taking it for service though.

 

There was a post a while back recommending disabling auto start with diesels due to shortening the life of the very expensive DPF ($8k in my case). Does anyone know the trade off of idling vs stop start? For example, shutting the engine off for a 10 minute train crossing is probably less damaging than idling for 10 minutes. But is there a trade off time? A 2 minute stoplight or more, shut the engine off, or?

 

Given diesels have no spark plugs to foul up I’d imagine long idling isn’t a problem?
