Based on that information, my guess would be the problems are linked to low battery voltage. Modern cars and their electronic systems are very susceptable. Try a spare battery or take yours out & slow charge it for a few days 'til it's showing around 12.6V, hopefully that might solve it

When BMW’s start to Chuck warning lights after having a flat battery it’s normally a sign the battery is goosed, when replacing a bmw battery make sure you get it registered on a diagnostic machine

INPA or ISTA. Depends on the year and what you want to do. INPA was replaced by ISTA. The BMWs bump the voltage up when charging an older battery to extend the useful life. The IBS is known to cause some weird and wonderful issues.

Do any of these things relate to our cars Jamie?, curious with the BMW links and underpinnings of the 75. Chris |

Haha, nope they don't the BMW systems are far more intricate, the electrical systems in the 75 are actually very basic, they are a basically a very simplified E46 electrical system.

Bumping up the charging voltage will NOT EXTEND a batteries life. ( As BMW found out when they learnt a bit more about batteries. ) Last edited by COLVERT; 2nd September 2020 at 21:31.. |

Bumping the voltage up can potentially get some charge in an iffy battery, but it’s by no means something that should really be done. There’s more to the intelligent charging system than that though |
