Golf mk7: Integrated Remote Garage Door opener/closer

[DV52]

Thanks DV52 for the detailed instructions.

I'm interested in seeing if I can replicate your good work. A few questions if I may.

Why do you need to purchase a second set of switches? Couldn't the blanks be used on the original or are they missing the switch component?

From the following thread I thought different part numbers were required for the switch modules?

Custom OEM looking WiFi and Garage opener buttons - Page 2 - GOLFMK7 - VW GTI MKVII Forum / VW Golf R Forum / VW Golf MKVII Forum

Is the part 5GG927238E that you used a black\satin finish?

Thanks

Steve

Steve: What an excellent question! Here's some pictures of the pertinent parts of the switch module that are critical in me answering your question (refer to the 3rd picture in my first post to see how the bits fit together):

First a picture of the switch base which contains the LEDs and the driving electronics (I've shown the "switch pads" for the Park Assist and Garage opener switches for later reference.




Notice that only one LED-set is populated (for the existing Park Assist switch). I guess that it really doesn't matter if the LED for the Garage Remote isn't on the PCB since the general illumination LED that's missing from between the 2 switch-pads at the end of the PCB isn't needed

2nd picture shows the part that I have called the "White insert" in my first post:


The white insert connects to the switch cap. The way that the two pieces connect is via the locating lugs shown in the picture above - there is a matching set of mating tags on the underside of the switch cap which holds the cap to the insert (see picture below). The bottom of the white insert pushes onto the "graphite pad" that sits on the switch-pads in the picture above. There is only one "white insert" on the existing switch (which lines-up with the Park Assist position)

3rd picture shows the underside of a switch cap compared to the underside of a blank cap (sorry that the pic isn't crisp!):


As you can see, the important part of the switch cap is the mating tags (for the lugs on the "white insert") - the blank cap doesn't have these tags. When I first started this project, I tried grinding back the insides of a blank cap, but the process was too fiddly to work!

I'm also not sure if marking the function of the switch cap for the garage opener is such a good idea (as per your link). My preference is NOT to advertise where the garage opener is in the car - you will know where the switch is and that's all that's needed. But if you want to spend the money getting a fancy switch cap symbol (something cryptic), then that's OK too.
Cheers
Don

PS: Yes, the unit that I show in my first post is a black satin switch module

There is an OEM option for garage door controller in sunvisor.

JustCruisn: Thanks for the response. Yes, the sun-visor option was the method that I was using before I implemented the change described in the 1st post. Ain't noting wrong with the sunvisor option, it just isn't hidden (integrated) into the car!

Don, just wanted to say kudos for another elegant installation! Your level of dedication to clean, OEM-style work is inspiring.

Sorry to dredge up an old thread, but thought I'd add a point I thought relevant.

Picked up a new Golf 7.5 a few weeks back and during change-over the salesman explained that the storage compartment in front of the gearstick is amplified (I assume for phone signal). As I discovered, this also works a treat for my garage door opener - the range has increased enormously! I previously had to be within a meter or so of my garage door before the remote would work, whereas now I can open the door from long range.

Hmm. By my count, my comfortline should have 2 blanks per side with stop/start being center LHS and park assist bottom RHS (I dont have the car yet, gets delivered this week). 2 single doors + house alarm arm & disarm = 4 functions. Could be fun.

Im_No_Pro (neither am I) - Hi and congratulation on your new purchase. I assume that you are referring to my fix. If I'm correct and whilst I hate being the harbinger of bad news - I'm not sure if you will have the degrees of freedom with the blank switch positions that is inferred in your post.

Here's a copy of my understanding of how the switch-set is connected in the RHS fitting of the center console (I believe that the LHS switch is similarly arranged)



Notice that except for the "Tire-set" button, each of the other switches have one end of their contacts connected together and connected to the car's earth. The reason that I selected the "Tire-set" switch for my solution was that it was the only switch with contacts that were independent of the other switch contacts and also independent of car's other wiring.

The problem with my suggested solution if you use any of the other switches is that you are interposing the car's earth point into the ciruit for the remote garage activation fob. I guess that you could be lucky for this not to be a problem if you use the fob battery, but it's a risk that can only be mitigated with a copy of a ciruit diagram of the remote garage control device (not usually available). Most definitely don't do this without a wiring diagram of the garage opener if you elect to replace the battery in the remote garage device with a power supply that is related in any way to the car's battery.

The other solution that you could try is to cut the copper track on the printed ciruit board for the switch bank (2nd last item in the picture below) that earths one end of the switch. This then isolates the switch, but you will need to find a vacant pin to connect to the now isolated switch contact

Thanks Don - you are likely right, I went reread the thread in a little more detail last night and had picked up on that as most likely being an issue. The remote is part of the alarm system, each button will be mapped to a function in the alarm panel (i.e. buttons 3 & 4 will trigger outputs which are hardwired to the door openers), the remotes supplied with the door openers are not used (or at least wont be once i'm finished with the alarm system). The remote in question would be a Bosch HCT4UL-FOB.

That being said, I ordered my OBDeleven yesterday, I think that will be keeping me amused for the time being ahead of this project. First car in 10 years that is mine, company cars have their advantages (i.e. cost nothing) but you cant play!

Im_No_Pro: in that case you may be interested in reading THIS - the thread was started by a colleague with a suspiciously deranged, but well meaning brain - he's OK to be let out, but only if accompanied by an adult with an electric cattle prod!

Golf mk7: Stealth Garage Door opener - Open Sesame!

Not sure how many mk7 drivers have a remote control in their cars to open/close the garage door, I certainly have one of these units mounted on the sun visor (or it's rattling around on to centre console)

Hi Don,
I know it has been some time since you posted this. I just finished my installation and this thread was immensely helpful and cut out a good 90% of the work.
I purchased my Golf only 4 months ago and have spent a lot of time on various forums and every time I see a well documented post I am never surprised to find your name at the bottom.
I just wanted to drop a message to let you know that I (and I assume many others) are very grateful that you spend the time and effort to make posts like this.

Cheers!

I was motivated by DV52's excellent post and bought the same switch from AliExpress to do the mod for my 2019 Golf R. I also got the wiring loom for a minimal extra cost, and this gave me easy access to a couple of wires ready-fitted with the pins for insertion into the connector plug.

The two switches looked identical on the outside. However, I soon realised that the switch caps were different internally and, when I fully dismantled the switches, it was obvious that NONE of the internal components were interchangeable. Since I wanted to keep two blank switch tops I couldn't now use the new switch. Fortunately the old switch had a full set of contacts inside and only lacked the suitable moveable piece that allowed the parking assist button to operate.

After some serious surgery on the fixed block under the (unused) tyre reset button I had a newly-moveable piece and it was now working perfectly. Wired up with the garage remote tucked away it's great. Many thanks to Don for his contribution.

Thinking of just getting this. It’s compatible with cars with camera and rain sensor.
