The trunk does not open! 135i HELP!
All of the sudden, the trunk does not open. In cant hear the solenoid unlatching. I check the valet switch on the glove box but is on the unlock position. Does not work with either the remote control or from inside of the car. When I lock/unlock the car I can hear the lock activation/de activating on the trunk.
Is there a fuse/relay location I can look into? |

Dumb suggestion. Have you tried putting your full weight on the trunk to see if it will click down farther? I believe this happened to me one winter due to ice.

I would go manually open the trunk with the pull cable and see if you can see any damage to the latch mechanism

I just checked the manual if there is an over ride for the trunk mechanism.
If it is malfunctioned it looks like they want you take a dealer, so no other easy over ride or help from there There is a lock/unlock switch in the glove compartment maybe that is preventing you from opening the trunk? :-( |

I could wire jump the trunk release mechanism to make it work. There must be something else upwards the circuit that is not working. While troubleshooting it opened once but no more after that. Tried to replicate the process but did t do it any more. I will have to take it to the dealer but I'm not prepare at this time to be raped. Will have to wait until settle at least 500 aside. |

I opened the trunk with a long rod, between the rear seats and a couple of cameras. Took me a while but finally I could pull the emergency release and open the trunk. Still does not work as it should. I wonder if I dessconnect a cable while working around the fuse box. I did use the camera but could not find anything like that. When I have time to work on the car I will give it another go. |

At least you confirmed the mechanism is mechanically sound by operating the emergency release.
So the fault is likely electrical. Pull off the lid cover and disconnect the harness to the lock actuator. Get an assistant to operate all the boot release buttons (key, footwell button) while you check for battery voltage on pin 4 of the harness. Connect your negative multimeter lead to the battery negative or pin 3. If that checks out, then check the ground wire on pin 3 of the harness (volt drop check). If that checks out then you might have a fault in the lock actuator such as a short or open circuit. Refer to this: https://www.newtis.info/tisv2/a/en/e...tlputs/bykETkj |

Im Having a similar problem
Quote:
Idk if there's any forum rules being broke, sorry if there is I am desperate for help, I am having the same problem except mine tweaked out after messing with my radio, according to your wire diagram you provided, it seems this is part of the "Central Locking System" so would if be safe to say the fuse that corresponds to this could be the issue? I have an aftermarket Dynavin Radio in mine that after trying to get power to return to the radio, My trunk latch stopped working. I figured I blew a fuse somewhere messing with the power wires something that must draw from the same Fuse. I'm about to run to the parts store to buy some more mirror glue since the roads here are crap and a pothole made the glue on my rearview mirror give, (I'm Praying my rims are bent, I hate Indiana ) sorry long rant, but just trying to get a solution to this issue while I have some time down off work. Thanks in advance for anyone that answers! |

If you have to now, you can remove the speaker on the rear seat shelf and under the fiberglass insulation stuff you can access the cable to pull the seats down. I had to make a small cut on the sheath of the cable to get at the wire which I pulled with needle nose pliers and got the seats to drop so I can open the trunk with the emergency cable. It's a PITA but if you have to open the trunk and there's no other way besides taking it to bmw, it's worth a shot, you can at least better diagnose the problem with trunk open. M |
