Retrofitting Heated Steering Wheel

[phanouf1]

Bonjour, j'ai suivi vos échanges avec intérêt, cela m'a permis d'installer un volant chauffant de golf mk8 dans ma golf mk7 de 2014. Un grand merci grâce à toutes les informations j'ai pu activer le volant chauffant. J'ai juste un problème c'est que j'ai le régulateur de vitesse et le limiteur de vitesse de base, j'ai donc mis les boutons en conséquence sur mon volant de golf mk8 mais je ne trouve pas le codage pour faire fonctionner le régulateur de vitesse ou le limiteur de vitesse. Pouvez-vous m'aider. Merci

@phanouf1 Do you have a 3Q0 gateway? And with what software? The adaptations are in the gateway.

 

[phanouf1]

I have a 5Q0 gateway, is it mandatory to switch to a 3Q0 gateway and if so is there a tutorial? Isn't there component protection that can cause problems? Thanks for the quick response

When I was doing the Mk8 wheel various retrofitters told me that 3Q0 gateway was required, with latest (at the time, a couple years ago) software. I'm not sure how/if you will be able to get all the buttons to function without having a adaptations for them in the gateway.

Yes, component protection and restoration of all SWAP/FECs. Any shop/dealer/person with ODIS online can take care of component protection. Restoration of SWAP/FECs is apparently not so easy anymore going from 5Q0 to 3Q0 so for that you will have to reach out to one of the retrofit companies.

Thanks. Do you have any idea what channels to check?

The channels don't exist on 5Q0 to my knowledge. But on 3Q0 gateway with later software...

Hello all,

I did this retrofit (with a Mk8 wheel) on my 2021 Volkswagen Golf GTI (Manual) about 2 weeks ago and it's been working as described below since. I am writing this here in case anybody else with a 2021 (this year specifically had things like the 3Q0 gateway and MIB3 system) has any issues or questions. Sorry for the lack of pictures, I'll try and add some when I can

• Clock Spring (5Q1953569D --> 5Q1953569K)
  • VW Parts - My 2021 had a 5Q1953569D clock spring. While searching for a 5Q1953569B clock spring, I noticed they were all $120+ dollars and instead ordered the stalk/clock spring combination (5Q1953521KRIGI) which came with 5Q1953569K for about $50.
• Steering Wheel ([ Not sure the PN, but it was the one that came with the car ] --> 5H0419089FNYPG)
  • eBay - The wheel I ordered was pulled from a Mk8 GTI (not sure if all of them are heated and I just got lucky?) and came with the touch recognition (also known as "KLR") module (5H0959542J) as well - ~$200
  • Capacitive Button Swap
    • As is (was?) standard on the Mk8 GTI wheels, the Capacitive Buttons (and trim) came with it. I swapped these out for the non-touch buttons. For that to happen I needed the trim and the buttons:
      • Trim
        • VW Parts - 5H0419089FGVDH (~$37)
      • Buttons
        • VW Parts - 3G0959442QVJA (~$116)
        • NOTE: If you have ACC and are looking for a set of buttons that only has the Driver Assist icon and not the Travel Assist icon, as far as I know, such a combination doesn't exist. Best I can tell, heated steering came with the 'fully loaded' trims of the Mk8's so that's why the Travel Assist icons pair with the heated steering buttons (and therefore have the third connector on the back of the left-side of the set)
• Airbag
  • eBay - Went to eBay for this one because I needed pictures of the connector before committing to buy. I was looking for the 6-pin connector that could connect to the set of buttons I ordered for the wheel. I eventually found one that looked good (from Europe) and waited the couple weeks for shipping. It arrived as described, however when I went to put it all together, I noticed the yellow Airbag <> Clock Spring connector had 2 more wires than my old Airbag and Pos/Neg Airbag wires were pinned differently :-/). I therefore had to re-pin the Airbag connector (presumably because I had a European one; by pictures on eBay, all the NAR ones are wired closer to what I found on my Mk7 module) and remove 2 from the tightly-wrapped harness. After pouring over european ErWin diagrams for various model years and lots of testing, the wiring configuration I ended up with is as follows (Red/Yellow were removed from the harness):
    • 
    • NOTE: An easy way I found to tell between the EUR and NAR airbags (if that is in fact the distinction...I'm quite new to all this) is by looking at the two wires coming from the actual airbag connection. NAR uses Green/Black wires, while EUR uses White/Yellow.
• Adapter
  • Kufatec - I ordered the Kufatec adapter thinking I wouldn't need to modify it; I had to re-pin the entire thing and remove 4 wires from the harness altogether (huge thanks to @mannymoda for doing all the hard investigative work!), so if you're thinking of doing this retrofit just order one from AliExpress or make your own adapter. Basically the 16 pins coming from the car had only 7 wires going to it (4 less than the Kufatec adapter did). I simply moved the terminals around on the 16 pin side of the Kufatec adapter to mirror mannymoda's findings
  • Add-A-Circuit
    • Local Auto Parts Store - I really, really wanted to add the Kufatec wire to the fuse box but after several tried in -15F I gave up and just used one of the widely available Add-A-Circuit's
• Coding
  • VCDS - Coding to get heat working seemed pretty trivial once everything was re-pinned and hooked up. I'll go through the admap to extract all the changes but I got everything I need from pages in this thread. From memory (could be wrong), "19 - CAN Gateway" held most of the ones related to Heated Steering while "A5 - Frt Sens/Drv Asst" was needed to tell the car to use the new KLR module.

• Issues
  • ACC fault(s) that didn't initially go away - Cleared DTC's in VCDS but these persisted after a short drive/ignition cycle, they seemed to clear itself!
  • Travel Assist Button doesn't bring up the Driver Assist menu on the MFD - going to the Driver Assit page on the MFD and then hitting the Up/Down arrows on the wheel brings it up, so it's not unusable
  • Heated Steering Button only turns heating on/off with one press/press and hold; I have activated multi-level and can change it in the Infotainment screen but can't seem to do it via the Wheel itself... Not a huge deal for now since it works and in the middle of a midwest winter where I can't think of any reason not to set it to the max

Thanks again to everybody here!! Hope this helps someone else and if anybody has any tips/pointers for what I'm assuming is my shoddy coding job, please let me know!

I meant to bump this thread a week or so ago. I decided to change bit 4-5 of byte 13 in HVAC module [08] to '. . . auto mode, Outside temperature' to see how the car would react; seeing as I have the climatronic system in my GSW. I've had this changed for the past 3 weeks and I haven't quite figured out the logic yet as it will turn on about 80% of the time on it's own after I start the car and the temperature is below 40°F. It is nice to have the steering wheel heat up without prompting it. At least during winter.

 

[Meesters]

Yes, I have similar coded, very nice when it goes on automatically.

Have you noticed any consistent behavior? I figured today, with the temperature at 35°F, that it would have turned on by itself. It didn't, so I just turned it on manually. I also thought it might be loosely tied to seat heater memory (which I have changed the adaptation to remember last setting), which doesn't appear to be the case.

 

[Cuzoe]

If you change vehicle type to Skoda in the long coding (it's in the first byte or 2) then you get the option to have steering wheel heat turn on anytime you turn on heated seats. It also gives the popup on the bottom of the screen to confirm the heater selection and show steering wheel is on. You get an option in the HVAC page to turn off this syncronization.

Worth noting you select the steering wheel heat level in the menu. The steering wheel will always respects that setting. It does NOT adjust (low, med, high) with the seat heat setting.
This hasn't been an issue thus far as I always have the steering wheel on highest setting, even if the seat is set to low.

Also worth noting this setting does not mean you must have heat and steering wheel heat on. Only that turning on seat heat turns on steering wheel heat. The sync is one way in that regard.
When you turn on seat heat, you can tap the (amber) steering wheel heat icon on the screen to turn off the steering wheel. And turning on steering wheel heat (via the screen or with MFSW button) does NOT turn on seat heat.




The setting that you are talking about @Kushdaiin I believe is this one, which I have not activated yet (screenshot below from @Nuje).


I suspect we should be able to get both options...
Automatic activation/deactivation (based on temp... is that wheel temp and/or outside temp?)
Synchronization... which turns on steering wheel heat if you turn on heated seats.


Unrelated, but in the screenshots... I don't know why I'm missing the Automatic air recirculation option... probably some adaptation change. And the supplementary heater option is the PTC heater that's in some TDI's. Oddly enough my US delivered car (that was set to "hot climate" from factory) has it but Nuje's Canada delivered TDI does not ?‍. I'm not aware of any way to manually turn on the supplementary heater so I'm not sure what happens if I un-check automatic... maybe I'm effectively disabling it.

Well, I don't have any inconsistency, I think. I set the threshold to 5°C, outside temperature. I did not turn on seat heater memory, although it still remembers a short while the seat heater level, when turn off and leaving the car. For my opinion, with my coding, it works the same way, when I turn "off" the steeringwheel heater manually, it remembers that for a while. Don't know how long, 15 mins? 30?

I will keep an eye out.

I do have an MK8 steeringwheel with SW heater button, therefore I disabled the combo function on the clima unit in the menu, the option is still there though.

If you change vehicle type to Skoda in the long coding (it's in the first byte or 2) then you get the option to have steering wheel heat turn on anytime you turn on heated seats.

Is this for clima units that original not come wirh the combo button?

 

[Kushdaiin]

I set the threshold to 5°C, outside temperature.

Interesting. I didn't even look for a threshold temperature in the adaptations but that makes the most sense. Thank you!

Synchronization... which turns on steering wheel heat if you turn on heated seats.

That option actually popped up after I installed the HVAC panel with the combo seat/steering wheel heat button, which automatically turns on both. This panel also automatically popped up the soft buttons of the seat and steering wheel heat after pushing the physical button. Must be the firmware/hardware configuration in the panel. A little redundant but it does follow the same logic that was in our old Tiguan.

 

[Cuzoe]

True... is probably all dependent on HVAC firmware.

@Meesters you may be right and I didn't think of that. I have the touch panel so there is no combo button. If I didn't have the Mk8 wheel having the popup when turning on seat heat would be the most convenient way to turn the wheel on/off. It would avoid using the climatronic panel Menu button.

Also I'm now thinking (with my brain, not my wallet)... is there a touch panel that has the graphic for steering wheel heat?
