Review: TL105 Electric Tailgate Lift Assist System (i.e. power tailgate)

Hi All,

So after having a pretty difficult experience in picking up a power tailgate lift for the X1 from AliExpress I finally bit the bullet on the TL105 Electric Tailgate Lift Assist System:

http://www.che1.com/product/tl105-el...assist-system/

I haven't quite gotten through the install yet (3 hours in at this point and had to pack it up and take a break), but in the meantime I figured I would post my unboxing and some first impressions.

First off, words of caution for those thinking of getting this:
1. This is not a fully reversible install - you have to cut 3 holes total: 1 in the large plastic trim, and 2 in the metal part of the gate near where the strut supports are attached (I'll post photos later)
2. This thing is LOUD. I'll take a video of it in action later, but I was quite surprised by just how loud it was.

The whole thing came in a surprisingly small package, but everything was packed up really surprisingly well.

Unlike the first set that I ordered which ended up springing apart on me and nearly damaged the car, this one comes with 2 supports for the gate, but their constructions looks virtually identical. That said, the control box looks far more superior and all the wiring is plug-and-play, no splicing or cutting of wires required (you just unplug the factory harness, and plug the new harness in between).

Last photo on the right you can see the two hole saws that are required for cutting the 3 holes I was referring to before. I have to say I was extremely shocked at just how sharp they were (especially the one for cutting in the metal).

Alright, that's it, will post the rest once I get around to completing the install, taking the video, and editing it all, but so far I'm pleased with what I'm seeing.

So, after 3.5 hours spent in the garage installing the gate it's finally done and ready for a quick review.

The installation process was fairly simple. The installation instructions were mostly pictures with some descriptions and really only provided a general sense of what to do, for the details you have you use your imagination. Took me some time to figure out all of the wiring but as a nice surprise all of the plugs are unique and not interchangeable so you really can't incorrectly plug something in.

The hardest part of the installation was running the wire from the battery to the controller - see the second to last photo, the red line is where the wire is run between the metal panels, through the rubber boot, behind the headliner, and behind the interior paneling.

Additionally, in photos 3 and 4 and you can see where I had to drill into the metal - it's where the wire from the supports goes into the metal.

As for the functionality itself, the button on the remote works to open and close, the button by the driver's seat works to open and close, and the button that was installed on the gate (see last photo - on the top) works to open and close as well as to set the height to which the gate opens.

A couple points of note:
1. The anti-pinch feature which stops the gate from closing on top of someone works but it's a little rough (more of a shove as opposed to a gentle push)
2. IMPORTANT: At a certain point (about 10-12 inches from fully closed) the anti-pinch feature stops engaging and the trunk gate slams - strong enough hazard that they included warning stickers and in my opinion for good reason. A little concerned how this would be with little kids.

Opens and closes fairly quickly (see video), but it's really rather loud. A little concerned about the noise bugging our daughter, I guess we shall see. I'll update once we've had it for a while.

Great review, thanks for taking the time to post all of the pictures and video too! The last-minute acceleration near the bottom of travel is impressive!

Yeah, impressive and a little scary when you realise how much force there is and that someone could accidentally try and catch the gate and get hurt.

TL105 Power Tailgate Lift System Kit

I have only just a few days ago joined this forum and just seen you thread on the installation of the TL105 Power Tailgate Lift System, and observed some of the details of the installation and the fact that it is very noisy.
I don't know if you ahave picked up on the posting I have put on this forum of me installing this system on my 2013 X3 F25. If you scan watch it you will I did not have to drill any holes into the cars body to install it and mine is no were near as noisy as yours, but this may be because when I came across this system advertisment, it was advertise as the second generation. So I think they have improved the installation quit substantially.

If could you tell me how i can up load vidios on a thread of this forum, i could up load the short video of my tail gate opening and closing with the sould track.

Have a scan look at my installation Youtube URL .
