Drivetrain and Battery Issue 2021 X5

[Monkey 9]

Hi, vehicle just out of warranty by a month and started getting intermittent fault. 

Driving along, suddenly ‘press start button’ appears and car dies. Press start button and all ok. Then drivetrain warning fault appears on dash, dive moderately. Usually a few miles later get a battery warning ‘do not drive car battery fault’. Stop car, restart and fault codes have cleared!

Sometimes doesn’t  re-occur for many days. I have noticed that it usually occurs when I”m slowing down and driving very slowly.

Other than that car drives perfectly normally, everything works as normal and have not experienced any starting issues to indicate poor battery charge.

Anybody help? 2021 X5 3.0D 63000 miles

Many Thanks

Andy

Hi Andy. 
my first thought is a dead battery cell. Either replace the battery or check the alternator for correct output power. 
 

cheers.
