Hi, I have an ongoing problem with a battery drain.
Garage traced it to a faulty Bluetooth unit,car was fine for a week then battery went dead.

It’s going back to the garage again for more checks.

The battery is new,but these models seem prone to electrical faults.

I’ve fitted a battery isolator, but am getting tired of popping the bonnet every time.

Is there a voltage drop box I can fit to the battery with added Bluetooth that shuts off the battery if it drops to a pre set voltage ?
At least then I can monitor the battery voltage on my phone, and reset it without popping the bonnet.
That would allow me to check if I still had an ongoing problem.

I would also add that I still would have any faults repaired. Thanks.
