MK7 Climatronic upgrade with instructions and pictures.

[Goodbar]

Or were you looking at position with the climatronic panel, so physically V113 but the panel expecting V425 with position sensor?
- Did you happen to see @Jachas post here about how the Climatronic Intake (dual door, and V425 works?
- Maybe the 32% you're seeing is also an estimate.

This was connected to the Climatronic panel. Thanks for reposting Jachas's info.

For sure, despite the recirc function not currently working I have not touched the climatronic panel a single time since doing this "most of the way" retrofit. It's been set at 72 which gives me a little heat in the morning and cools right down in the afternoon when I leave work. There's nothing weird going on with the air direction either. I'll run out at lunch here in a few minutes and flip Byte 6 bit 3 just to see what happens, assuming laptop isn't dead. I do have OBD11 in the car but firing up the Surface and using VCDS is faster.

Edit: No change to fault when swapping that bit.

Went ahead and ordered a 5Q0907511L for just under $30 shipped. Used, from a 2019 something or another according to the listing. There are also new non-valeo branded ones for $15. Anybody tried those?

 

[Cuzoe]

Well folks, 5Q0907511L from eBay showed up today, 3 days before estimated. Plugged it in and no "position sensor short to ground" fault. I'm also now seeing a value in measuring blocks, where before it just showed unavailable.



The only fault is no basic settings which just means running the flap end stop procedure once I actually install this motor. Will have to pull the glove box again so could be a week or two. But once done I'll have a single zone climatronic with no faults. I am very excited!!!

This is incredible! Congrats. I suppose two zone climate control is the next objective. And don’t tell me it’s too complicated. That hasn’t completely stopped you before.

It is possible, but not everyone (I think anyone) wants to take dash and dash support out (and coolant + refrigerant needs to be drained) to change entire airbox and wiring. Simplified to one zone is much, much faster and easier job + no need to dismantle entire car is huge +

On the contrary two zone I think is (sort of) simple. Remove the dash and put in the right box. The harness is inexpensive and when you have the dash out the harness is trivial to install.

And at that point I'm not sure it's impossible to go 3 zone. If I see a 3 zone box on eBay for under $200 shipped I'll buy it. Not because I'm going to install it, but because it's really hard to tell from pictures if there will be a clearance problem with the additional gears/arms. If I had it in front of me I bet I could give a good answer, and I do think there would be an issue... but like I said, I'm not positive on that.

I don't know about the non-touch climatronic panels but the touch climatronic panel certainly has the ability to address three zones. If my poor deciphering of German is correct it can actually address four zones. I don't know if VW sells anything in the states with 4 zone. The Toureg is still sold overseas and can get 4 zone, but based on the dash pictures it doesn't have this HVAC panel. I'm pretty sure I saw something on ebay listed as "rear condenser" when I was looking for the HVAC box, but not sure what car it claimed to come from.

But touareg is MLBevo (so close sibling with Q7/Q8/Cayenne/Urus) and even then, Touareg built on MLBevo has only one evaporator and heater core up front (but with 4-zone has 2 blowers, one for front and second for rear)

AFAIK, only VW with 2 evaporator/heater core are VW sharan (something like Pacifica, but EU-sized and made by VW for EU market), VW T5/6/6.1 Transporter/Caravelle/Multivan (mercedes Metris size-wise, en EU offered as Mercedes Vito/V-Class) and VW Crafter (Ram pro-master size-wise, in EU as Fiat Ducato and many other brands, as is very popular badge-ingeeneered in EU, like 5-6 brands in EU + RAM, but not offerend in EU as RAM)

Sharan is PQ platform
T5/6 has PQ based/style electronics
T6.1 has MQB based/style electronics (but I dunno if compatible with "regular" MQB
Crafter similar to T6.1

And at that point I'm not sure it's impossible to go 3 zone.

As we spoke earlier, IMHO eletcric/coding wise, should be possible (In case of NAR, the easier to obtain would be Tiguan airbox and AC Panel, in EU passat B8 and Touran had 3-zone too) My only concern is space constrains

So, I'm back, but I'm feeling as I lost a battle :/

I can't get the AC clutch to engage on the new control panels, no matter what.
If it makes a difference, I got a 2020 GTI 6 speed manual, thus MK7.5, manual AC control P/N 5G0907044G.

I sourced cables and sensors from far China, but used 2 different NAR OEM control panels:

• 5G0907044AN
• 5G0907044CF WZU

Like many soldiers in our quest, I can't get the AC to turn on, after countless attempts: using the infamour 8+16 key press combination, nor 8+17, nor any variation of these methods holding it pressed for 2 minutes, turning it off and on again, and driving afterwards.

Both panels I bought had coding differences with my car's original unit. I copied every single config, one by one, and tried many variations of them all, no dice.

I noticed that not even the original panel was able to start the compressor run-in procedure through OBDEleven, even that one would show the ERROR: marginal conditions not met message, but I found that it would click the clutch when I did the Output Test -> A/C Clutch function - it clicks even with the engine off, easy to hear.
None of the sourced panels would be able to make it engage, not even after a shitton of fiddling with the configs. I also noticed that both of them did not have magnetic clutch configured, whereas my car does have it.

@traan.man48 was able to get his AC working with a P panel, and now I'm tempted to get a newer one.
I'm guessing VW updated something in communication protocol or such that it will only work with later revision panels.

If anyone has any ideas on what I could try to get this lovely A/C going, please do tell!

My second Climatronic panel is an H rev and initially wouldn't start the A/C compressor because apparently the donor car was in a wreck and that disables it. Did you scan for faults? I found a thread that indicated that you have to start the car to allow it to reset, IIRC.

Yeah, I did. Both of the panels had a lock out fault due to crash signal, but they cleared out after the engine was on for a while.

I don't yet have the time to make a proper thread but my most of the way retrofit is almost done. Got the replacement motor for the recirc/back pressure door.

Managed to install it using the pictured "tool" which was no fun. When I run the end stop learning procedure it says completed successfully but the basic settings fault for thar motor/flap doesn't clear.

Real time values now properly show position and if I choose recirc or fresh air the commanded value changes as does the position. I verified in measure values and looking in with the filter removed. It's also pretty obvious when switching between research and fresh air if the fan is at 2/3 or above.

Blah blah blah, everything works as it should but I'm not sure why the end stops can't be learned. So close to having no faults that I have to figure it out.

I'm thinking when I get time I'll pull the glove box again and pull out that duct assembly. I can then run the adaptation while being able to see what the motor is doing.

I would like to ask for your help to obtain instructions on how to configure VCDS for the installation and setup of the Digital Climatronic Panel. I need this guidance to complete the process correctly. Thank you in advance for your attention and assistance.
