MK7 Climatronic upgrade with instructions and pictures.

[Cuzoe]

It was not standard on our 2019 SEL-P Tiguan but was able to be activated it through the typical coding.

Interesting, gives me a couple questions...
- Does your now activated AirCare work? I don't know how you would check, I guess.
- What motor is installed here on your car (and by extension the box in the eBay link)?

- The picture in the listing is blurry when zoomed in but it looks like that recirc motor connector...
--- has more than just the two wires that are present on manual HVAC's V113
--- it doesn't look like the V113 wire colors (blue/yellow)


@Jachas So maybe a motor with position sensor is all that's needed, from the listing this a Valeo unit.
- Another listing has a non-faded label, and is the same on the intake, single door.


I can't find a good picture of that motor in a listing but I'll look through the parts diagrams.

As an aside, I have an entire Climatronic box (Valeo) on the way to me, with everything attached. Removed from a 2016 GTI Autobahn (VIN confirmed) and the seller sent me a picture of the inside of the car showing it's climatronic (although looking at the listing pictures was already enough to confirm). I'll probably have some spare motors/bits for sale soon... the ones I ordered in excitement 2 days ago, haha.

@Cuzoe unfortunately we traded that car in last November for a 2021 Atlas. I want to say it was a Valeo but don't know for sure. And it did seem as if the system ramped up flow when air care was activated, so I would assume it was doing something.

 

[Cuzoe]

@Kushdaiin No worries. I just "need" to find a listing with that box that has a clear picture of the motor part number.

I do wonder if the Climatronic panel is made aware (it would have to be adaptations I guess) of the presence/lack of second door on the intake since there's nothing electrically connected to that second door/flap.
The unit learns the stops, which may change since there is additional linkage attached. And that would be important so the motor doesn't overdrive/break anything.

 

[Kushdaiin]

That function is done when you do the flap adaptation process (forward airflow and A/C button or do it through VCDS) when you swap or install a new panel.

AFAIR, at least in Denso style witch have second door, it works in way that 3/4 of the maximum range of the motor and gearing is for opening and closing bigger flap for recirc function, 1/4 left is for aircare and back pressure.

And this range is "divided", like aircare and back pressure had its own, separated range. To visualize what I want so say



0-------|---------------------50--------------------|-------100

Aircare/Back pressure | Recirc | Aircare/Back pressure


At the beginning and at the end of engine range, the extra flap is opening or closing (This is what I remember form facelited Euro-spec A6 Jetta with climatrionic, with similar mechanism like in MQB Denso)

Right... I know how to do the function for adapting flaps. I was just wondering if the system needed to be "aware" there were actually two flaps. And whether it accounted for that at all.

Ahh that makes sense. Assuming it's similar for Valeo it would make sense that a position sensor is required. The box I ordered (removed from the 2016 GTI) is Valeo and has the dual doors/flaps on the recirc intake.


Once I have this box in hand I'll see how feasible it is to swap the intake over (without removing the dash).
And if it's not possible a fallback option might be to install whatever motor the single-door Tiguans are using, and add the two wires for position sensing.

 

[Cuzoe]

Valeo climatronic "box" showed up! Snapped some quick pics. Going to study it a bit once the kiddo goes to sleep. And I'll get some good pictures of every motor and mechanism and post them up for research purposes, haha.




The last picture is the bracket for KESSY module. That retrofit isn't done yet but if I knew I was going to end up with this thing I wouldn't have paid for that bracket.



I'm going to end up with a lot of things for sale that probably no one wants. Two full climatronic harnesses. One of them brand new. Several motors and gear mechanics. A sensor or two as well.

 

[Cuzoe]

So I've got the aforementioned Valeo climatronic unit on hand, so these part numbers (and pictures) are from that unit...

V107 - Defrost Flap Motor - 5Q0907511K (180 deg)
- I think we/I had a different part number earlier, maybe either will work.


V425 - Fresh Air/Recirculating Air/Back Pressure Door Motor - 5Q0907511L (340 deg)

 

[Cuzoe]

Well... Glove box comes out somewhat easy enough but the upper section of the air intake (with the recirc door) won't clear that metal tab that's hanging down. So close, but so far.

 

[Cuzoe]

It is made of metal, it can be bent, lol


You got to get a stubby and to remove the motor from the right side. Speaking of which here's a picture of that motor, it's just an on/off according to the writing...

 

[Cuzoe]

Added V107 - defrost door motor and the wiring/plug.
- disconnected the blue arm on the other side. I pulled the dashboard and infotainment trim, honestly none of that helped. Just get to it from the pedal box.

Replaced intake "box" with the proper one for climatronic, so that's replacing V113 with V425 and the correct motor. Three wires added and swapped pins 5 and 6 which the retrofit harness has reversed for whatever reason.

I previously added sunlight sensor and air quality/humidity sensor.

This should bring me down to only a few faults for the motor and position for the second temp zone. The box has the moldings for it, pictured here. The gear that would adjust the flap slots in but of course there's no flap there so it doesn't move. If it moved, even though there would be no physical flap moving, I would probably put the motor there just to clear the fault. But since it won't move I don't know what would happen. I suppose the system would find the end stops are right next to each other which would create a different fault. Maybe I'll install the motor after all .


Edit: After more inspection the stops are built into the motor housing so the system can learn them whether or not the gear is there to move that flap. As I'm sure you can imagine, I'm installing this motor and I should have a climatronic retrofit with single zone but no faults.

 

[Cuzoe]

It's all done, pulled the center console so I could add the duct to the rear vents. When I did the EPB retrofit I didn't realize there was a different duct for the EPB center console. I bought it then but couldn't be bothered to pull the center console to install it because it was cooling off, now it's getting hot again and I gotta keep the kiddo cool.


I've still got some stuff out, adding things to the fuse panel, I'll call it my "final" retrofits . Tonight I'll put the climatronic panel back in and run through everything. I should be fault free. Selecting un-synced temps will cause the ceremonially connected right side temp flap motor to adjust but the gears aren't connected to anything so temperature will always be based on the driver side sensor.

Air direction should be good now with defrost flap motor installed. Air Care should also now work and there won't be any recirculation issues since the intake box has changed. I don't really know what Air Care does. And I've gotta figure out the coding for it. Option wasn't there when I had the climatronic panel in before.

Maybe I'll open a separate thread for all of this shenanigans. I'll duplicate most of this over there but with a beginning intention to go what I would call 85% of the way to climatronic, which I'm confident is as far as one can go without pulling the whole dash to replace the box. As an aside I don't think three zone is feasible, lol.

 

[Jachas]

I can't wait for final results and thoughts of such thorough/extensive "doesn't requre pulling the dash" climatronic retrofit.

As an aside I don't think three zone is feasible, lol.

Technically (A/C control unit, coding, 3zone airbox,etc.) should be possible, as it only has 3 extra things in comparison to 2zone. One extra temp sensor and temp. control panel in the back. But the 3rd thing possibly makes it impossible to do it in golf. It is extra gearing and linkage on the upper left side of the airbox possibly would make spacing problems under golf's dash/central console(is the same gearing where Climatronic V426 motor is connected, but with more gear and levers that have linkage that travels to the bottom part of the airbox and moves the extra flaps (entire air-box swap required) from third zone

Some info is avaible in SSP542 (EU-spec Passat) , SSP548 (Touran, mini-mini van, EU only) SSP552 (SWB Tiguan, not avaible in NAR) Info about 3rd zone is small and almost identical between these SSP's

When searching SSP's with 3rd zone, I found in SSP557 (Arteon, page 31) more info about Air Care function

 

[Cuzoe]

That additional linkage for the rear zone is what I think would be the problem. I'll have to Google some pictures of the Tiguan center console and see what that looks like. Haven't been in one.

I saw what I believe was a three zone box on eBay and it looked to me like that linkage wouldn't have a place to live in the Golf.

I haven't seen a rear panel for the mk7. But when I first put this touch panel into my car it had controls for the rear zone (can't remember if it was adaptations or long coding). If the box fits it would just have to be managed by the people up front.

But of course that indeed means changing out the entire box which is not something I would like to do.

 

[Cuzoe]

Air now goes where I want when I want, it's glorious. I've got a fault for recirc flap position, gotta see what I screwed up... thinking I may have mispinned at the HVAC, which is an easy fix.
