MK7 Climatronic upgrade with instructions and pictures.

[StorableComa]

The Diagrams will include all optional equipment wiring as well. They're generally marked with * in the diagrams and a note about region/option. So the wiring diagram for a fully loaded model and a base model is the same.

tried, paid money, but only thing ive found was basic equipment diagrams

Im retrofiting Side assist and Lane assist, as my car doesn't have this my VIN is useless. I have cut outs of diagrams, but very little is missing.

Uh.. you get a single PDF that has every option possible. "Basic_equipment__From_August_2012" is a lie.

What's the part number of your panel? My stop/start is working fine with AC on (and off) with only the two upper vents connected.

Happy to compare my installation with yours to get to the bottom of the problem.

Hi IWMTom, that would be great, I see you're local to me as well.

Ok, so the first panel I tried was the cheap Aliexpress one, which was 51G907044G. My copy of VCDS couldn't seem to find any label files etc for that and I couldn't get access to it, so I bought a used one on eBay which is 5G0907044BD. VCDS now finds the panel just fine and I can get access to measurement values which I couldn't with the previous one.

2 Questions, if you have VCDS can you tell me what your coding options are, and if you click on the vehicle status on the infotainment unit, what does it say under the start-stop status?

I ask about the S-S status because mine seems to constantly say something along the lines of "Windscreen could become fogged" and "A/C requires the engine to be running". If I turn off the climate system completely then the S-S starts working again so it's definitely something to do with the A/C stopping it from working.

I'll begin with a sidenote - I did have the stop/start problem on a previous panel, but turning A/C off did allow the car to stop (just A/C, not the whole Climatronic unit). I've since installed another Climatronic unit as a result of obtaining heated seats, and I needed the buttons. This new panel has no issues, despite the coding string being the same (or at least I think it was the same... I swear I just copied it from panel to panel..)

I appreciate coding strings may not be universal between control units, so I've taken the liberty of screenshotting each byte from the Long Coding Helper, as well as obtaining an adaptation and block map. Due to the forum restricting uploads to 10 files, I've added the files to a Google Drive folder:

If you'd like anything further, feel free to ask!

IWMTom That's great, thank you for going to those lengths to help out, The symptom of SS working when you turn off the A/C was exactly where I was at with the Aliexpess panel, at present I can't remember if it's the same with the used Golf one, but I think it might be.

Ok, so I've just been out sitting in the car in my jim-jams idling the engine and looking at the coding.

As I suspected the coding was set to have an internal humidity sensor active, as far as I know I don't have one so I deactivated this and it got rid of one of the items listed on the SS status screen, which was "Windscreen could become fogged". However it still said "A/C requires engine to be running". This led me to try and run the A/C compressor run in again, which would not work, just faults out with a 'sequence' error, even after running the Flap endstops adaption. This can also be done by pressing the demister button and the A/C together but this didn't work either.

So.... I took it for a drive round the block, sure enough the SS wasn't working still, even if I turn off the A/C I still have the "A/C requires engine to be running" message, only if I turn off the Climatronic completely does the engine stop. Turn it back on and engine starts again. So I got back to my driveway, clima and A/C on, and was just about to give up when the A/C message disappeared, but the engine was still running. So I poked the SS on/off button and it went to deactivated, then poked it again and the engine stopped(!).

I tried this a couple of times and it seemed to work ok while stationary, my journey tomorrow commuting to work will prove whether this is just a fluke or if it's something that just needed to reset to start working again.

I'll report back my findings tomorrow.

Also; in your scan above, I can see you have the error messages similar to what I have, for things like the defrost and RHS flap which are to be expected, but you have an error for the Fresh/Recirc flap, did you run the flaps adaption? (or from the front panel).

I'd quite like to sort out the temp sensor errors on mine, so will try to get some more sensors and plug pins, same goes for the sunlight sensors.

Thank you for your help
Dave.

Sounds promising!

I haven't ran any adaptations as the panel was used so the AC worked plug and play. Does this flap adaptation have any tangible benefit? As far as I can tell it all seems to be working correctly!

Have you compared my adaptation map to yours? There could be something lingering in there that could help you.

In all honesty it probably doesn't make a massive amount of difference to the basic operation, it basically just tells the Clima unit exactly where the end stops will be, I guess it will prevent the motor from stripping any of the plastic internal gears if you press a button which makes it open/close really quickly.

It won't affect anything adversely and takes about a minute to do, just press and hold the A/C button and the demist/top vent button on the top row until the LEDs on those buttons start flashing, they'll stop once complete.

I've not actually compared the adaption map, in fact I'm not sure how to take an adaption map from my car? what I do know is my old copy of VCDS doesn't seem to want to load the adaptions module unless it's on the very first run on each session, so there's no guarantee it will work anyway :-/

Thanks, you learn something new every day! I'll do that at some point.. one less fault code!

From the VCDS home screen I think it's Applications then Controller Channel Map, input the hex code of the Auto HVAC module and set to CSV.

How old is your VCDS?

Ah cool, I'll have a look tomorrow and see if I can do a channel map as you suggest.

I think the version I'm using is V17 or something, I'd have to look on my laptop tomorrow when I get back from work.

Cheers, Dave.

Is it a legit copy, or one of those dodgy Chinese clones for £20 on fleebay?

That's a very good question which I'm afraid and not quite sure how to answer, as I paid a LOT for it at the time :-/ Cable is branded with all the rosstech logo's and details etc, comes up with rosstech design etc when you initially check the connection.

How can I tell if it's legit?

Cheers.

Did you register it with RossTech and gain access to the forum? If so, it's legit.

 

[davegsm82]

Hmm, no I didn't even know that was an option, when you say register it, do you mean via a serial number or something?

 

[StorableComa]

If you have an older Hex+CAN model Rosstech cable, you might not be able to access or code some features on the MQB model cars. This is why they upgraded to their Hex+Net and HexV2 cables, due to a change in string length.

Not sure if you're running into that issue. They do have an upgrade program though if you have an older model and want the v2.
