2018 BMW 1 Series rear lights coming on by themselves when
Discussion
Hi all, hoping someone can help with a strange intermittent fault on my 2018 1 Series.
Both rear tail-light clusters occasionally come on by themselves when the car is switched off and locked. It’s just the rear lights—the front lights and third brake light aren’t on.
A few details:
Pressing the brake pedal makes no difference.
Unlocking and relocking with the remote, or switching the ignition on and off, clears it and everything returns to normal.
It happens with the light switch in Auto. So far, leaving it at 0/Off seems to prevent it.
I’m getting “Battery discharging when stationary” on the dashboard.
Nothing has recently been changed or fitted to the car.
Has anyone had this exact problem and managed to get it properly diagnosed and fixed? I’ve found similar reports online, but very few follow-ups confirming the cause.
Would really appreciate hearing what actually resolved it before I start paying for parts on guesswork!
Thanks,
