Came back from a long vacation.

Car won't start - BMW X1, sDrive, 2015

- Battery Voltage was measured at the battery terminals - around 5V

- Jump started OK

- Battery Voltage was measured at the battery terminals - around 12.5V

- Kept car running for 6 hours inside the garage at night

- Shut off the car and measured the battery again - only around 5V

What could be wrong? Should try to disconnect the battery IBS?

Many thanks!






12.5v is low for engine on. It should be around 14V. 

Do you have access to a battery charger? If yes, recharge battery overnight with it. 

A faulty IBS will give a DME code. Do you have a scan tool?
