F34 Power hatch not lifting
The hatch will release, but not open when I use the key fob or push the button on the trunk. You can hear it click, but it won't open without a boost. I'm guessing it's the shocks, but I can't find any videos about replacing them and they aren't exposed like other shocks on my other vehicles. Has anybody has this problem and if so, do you know of any videos on how to replace them and the part number to buy? Thank you for any help you can give me.

I wouldn't assume it's the shocks, it could be the motor isn't working. It may be opened by either the spring force or electrically.You want to be sure of what's broken before buying anything. https://www.newtis.info/tisv2/a/en/f...outer/EWJoJ9ji

Also make sure to check in iDrive as there is a setting limiting how far it opens.

I did check the iDrive settings and changed it a little to see if that would help it. It was set on the highest setting and I clicked it once to slightly lower the opening height. Then I pressed the button and it opened, but that must've been the one out of twenty times that it opens properly because it hasn't worked since then. 😭

Same thing, only different
I started a new topic, but haven’t gotten any traction on it.
No matter which method (fob, cabin button, trunk button) the motor makes a whirring sound, but doesn’t unlatch. I literally have to drop the rear seat, climb in, and pull the manual release cable. I’ve had the ‘unlatch/no lift’ issue before, but have found pushing fob button caused a lift. This one kind of has me freaking out and I haven’t found it addressed elsewhere. |

What I do know is that it definitely unlatches and tries to lift (I can hear the motor), and successfully lifts all the way on its own after I give it a very slight boost after it unlatches. I don't know what to try first other than replace the shocks. I just can't find anything online about how to replace them or where to buy them. I've only found some on eBay that are used and most of them are in foreign countries. I hate my hatchback not lifting. When I have my hands full and my key fob in my pocket, I can put my foot under the back bumper but it won't lift up on its own like it should. I always have to set everything down on the concrete and give it a boost before it will go up which defeats the purpose of having the hands free lifting of the hatchback. I don't even know where to take it to have somebody fix it even though I'm sure that will be so expensive. |

Something else that I realized I never told you all but might be significant as to what the problem might be...it always always closes on its own with the press of the button. It's opening that it can't do without a slight boost after it unlatches.

https://www.newtis.info/tisv2/a/en/f...cks/1VnXHHnyP1 The only issue is that it looks like they need initislizing after fitting. I've got no idea on the consequences of not doing it. Here's a link to find the part numbers for the strut which should help searching for parts. https://www.realoem.com/bmw/enUS/sho...diagId=41_2244 Honestly I'd look for codes on the car first. It should help pointing you in the right direction, those struts are really expensive. Does the soft close still work when closing (does the tailgate get pulled into the lock slowly)? |

There a lot of info here on how the whole system works, which may help with diagnostics.
Electronics is not really my area at all but hopefully someone will come along who can help a bit more. https://www.newtis.info/tisv2/a/en/f...ation/DxBqFjue |

So I am having this issue now, it sometimes does the pop whirrrrrrrrrr without going up. It only does this on hot days, because when I try to show it to friends it works, and usually not midday hot. Assuming hydraulic failure based on the temperature, so the price on components here is what now? A metric asston? |

My tailgate hasn't failed yet, it was making stuttering noises when opening. I sprayed some lube onto the visible parts of the strut and the noise and vibration went away. |

I'm having the intermittent half-rise as well, also seemingly correlated to heat. Has anyone treated this successfully yet? Pop a cialis in each strut, or do they need a full replace? If so, does anyone have the part numbers copied down? The link is now broken.

I am going to bite the bullet on the struts probably end of summer, the ignition coils just started throwing misfires and limp mode so priorities.
From the looks of it, a straightforward swap minus the initializing. Is that something that needs done with a high end OBDII tool? |

My Bentley manual only says "Initialise automatic operation of tailgate using the service function in the diagnosis system". That probably requires dealer level software like ISTA.

I will update on price and how much of a pain this is when I get the parts ordered from a local dealer. |

Cool. I have an NT510, but never having had a problem with my hatch I had no reason to investigate if it would initialize them. 3rd party struts would be a lot cheaper than OEM, but I suspect there aren't any what with the GT being such a limited production model.
