Trunk Won't Open
Went to open the trunk to my 15 M4 and there's no click when I hit the trunk button, the fob doesn't open it, and the button on the dash doesn't do anything either. It went from works fine one day to not opening at all the next time I used it. Any ideas would be greatly appreciated.

Does anything happen when using the handle on the trunk itself? Sounds like you may need a trunk latch.

I have a 2019 M4. There is a release latch behind the headrest inside the car. And a pull latch in the trunk in the trunk lid.
OP, have you gotten it open yet?

Nope. I haven't messed with it too much since the trunk is empty and I don't really use it much. I figured it was probably the trunk latch since there's not a click or anything when ii hit the release whether it's the fob or the trunk itself.

Trunk refuse to open on my 2017 BMW M3.
I have the same issue. Have you found a solution?
Trunk refuse to open on my 2017 BMW M3. My battery seems to be ok, the car starts up no problem. I have tried the valet switch in the glovebox, does not help. I can lock/unlock and activate the alarm with the keyfob. But, the trunk will not release with either of the buttons, the trunk, the key fob, or inside the car. I really don't want to disassemble my rear seat and fish for the release cable. P.S. To make it more "fun", right before it happened, I bought some fruit from local grocery store, and placed them in the trunk. Drove one block to my house and this happens |

Update: Ended up taking rear seat off to get to emergency release cable in the trunk.
The fusebox is inside the trunk, no way to get to, before you release it. All of which are ok. Last edited by E92toF80M3; 08-11-2022 at 04:40 PM.. |

I vaguely remember seeing options in BimmerCode to deactivate some trunk access related functions. Did you code recently and deactivate by accident?

Had the same issue on my ‘18 M2. Took the dealer a few days but they found a short in the locking mechanism.
Ironically, my ‘19 M4 has a trunk that refuses to stay shut. |

Quick Update: Finally took my '17 M3 to the dealer, they found R.E.M. (Rear Electronic Module, Part# 61-35-9-499-001) has failed.
$1500 later my trunk is working again. |

In my case the trunk opening was not working occasionally for last couple months, but figured low battery voltage was the culprit bc it always worked eventually. Now it’s just dead, going to see if I can read it with BimmerCode. Ordered a REM from ‘16 F30, (same part #) on eBay for $40. Will see if that fixes the trunk when swapping. If so I’ll need to code it to have rear windows & camera work, and remove trunk dash light. If it doesn’t fix it I guess the latch could be the issue…but based on the amount of REM failures I’m seeing I’ll bet it’s that. Last edited by Alpine-F80; 02-24-2024 at 08:50 AM.. |

Interesting thread - didn't know this was as pervasive as it seems, definitely something I'm going to look out for! Alpine - would be curious how your REM replacement goes.
