Trunk won't open!
I have a 2011 535i and my trunk won't open out of the blue. I get into my car and pushed the button by the front door, no dice. I tried my key fob, no dice as well. I checked the valet switch in the arm rest, it's sent to unlock. I toggled it on and off just to make sure.
When I push the keyfob or the button near the front door, I don't hear the electronics for the lock engage. Any thoughts? Is there a fuse I should check? I don't have comfort access or the power close trunk. |

Things to check or try. This was an issue for the e60 but I bet it hasn't changed, the wiring went through the mounting hinge and would crack and short. When unlocked does the manual trigger by the plate work? If not I would say its the locking mechanism.

He says that he doesn't have CA or Power Trunk which makes this a bit interesting.

Very odd. I ended up using a rod through the pass through to engage the lever to bring the seat down. Once the seats were down, I used the manual pull inside the trunk to open it. Once the trunk was open, I pressed my keyfob, the trunk release button near the driver's side door and on the trunk itself and this time the lock made an audible sound. It must have been jammed or had a random hiccup where the lock didn't engage. Either way, I closed the trunk and tried all 3 methods, they seemed to work this time. Glad it was nothing!

It stopped working again! So frustrating. I will put some WD40, maybe it's a lubricant issue but I hope it isn't something else, I have friends to pick up at the airport on Thursday!

I once had a door actuator do the same thing. I shot some white lithium spray on the latch and it stated working again; for years! I would try shooting some white lithium grease on the latching mechanism. |

wd40 wont do anything, find some sort of lubricant and spray it onto the mechanism after unlocking the trunk from inside.

Yes you could get some lithium grease it will last longer potentially life time.

I'll add another twist to the WD40 saga.
WD40 as a brand makes White Lithium Spray, so WD40 (the right variant) is a lubricant! I have generously sprayed it on the locking mechanism and latch. Let's hope this solves things. |

cipher5 Are you still having this issue? I just started to have this on Friday. I have the comfort access though.
It works randomly, and the open from key fob just does not work. |

It has happened once again, but not much lately as I haven't been using the trunk all that much. I think if I used it more I would have that issue possibly. I will report back if I have more issues. It's the oddest thing.

So BMW can't make a reliabe V8 nor reliable trunk actuator.
As an aside, my 2016 trunk only opens half way about 95% of the time. No rhyme or reason as to why it completely opens 5% of the time.
