RX Auxiliary Battery Alarm Problem

Whoa, that sucks! I had something kinda similar happen with my old BMW 3 Series. A weird electrical issue kept popping up, turns out the car alarm was going nuts because of a weak battery. Is your battery old? Maybe try swapping it out?

Did your BMW show similar error codes related to the alarm system?

Yep! Showed some crazy errors. Honestly, I just took it to a shop after that, they sorted it out. Saved me a headache. Good luck!

The diagnosis also pointed to a battery issue and the estimated repair cost is 330€. I will replace it. Thanks for sharing your experience.
