I don't think so, this is not an arduino. They are signals that are sent through the BUS-CAN. There are people who are mounting the steering wheel of the Passat b8 as it has capacitive sensor and the steering wheel is the same as the id.3/4. The only thing you do after is to exchange the buttons of the steering wheel of the ID.3 to the steering wheel with sensor of the passat b8. What I understand is that this signal is sent from the same control unit of the id.3 button panel if the sensor is present and active. For me there are only two solutions: Buy the Passat b8 steering wheel and install it or identify the ID of the signal and through the ODB bus inject the value every 10 sg or so. so that the gateway receives that signal and thinks that they are touching the steering wheel. By the way the part number of the passat steering wheel valid for this is: 3g0419089bq for those who want to try it with the passat steering wheel, there are many on ebay at a reasonable price as the steering wheel with capacitive sensor of the ID.3 is worth about 600€ and the passat one can be obtained for less than 200€.

It would be necessary to check whether pressing any of the steering wheel buttons such as RES removes the warning to grab the steering wheel would be confirmation that the signal is being sent from the steering wheel button control unit. If this is the case, a device could be installed that pushes the button every so often. Tomorrow my ro if the button cuts off the request to grab the steering wheel and the TA is still active.

1) There is a control unit inside the steering wheel actually measuring the intensity of the touch. This one reports the touch intensity to the gateway via LIN
2) It is able to measure firm or soft touch, probably even one or two hands on the wheel. I am very sure that there is a lot of error detection done, so just shorting its inputs or putting a resistor on that will not be enough. Also, it might check for acutal changes as in real usage, so there might be some more circuits needed.
=> Conclusion: To simulate a KLR you would need to install and wire the KLR control unit. You will need to test a steering wheel's dynamic responses on touches and simluate that. When you are not chasing Henno's infinite LaneAssist, it looks to be easier to change the steering wheel.

If it is clear that the ECU of the button panel should have some pins where the capacitive sensor is connected, but who tests it and puts a resistor on those pins risking to damage the ECU ? Without technical information it is easier to change the steering wheel. Or looking at the connector on the steering wheel that connects to the ECU on the button panel would identify the sensor input, but you need to have a steering wheel with a sensor to see it. Without this information it is easier to change the steering wheel.

It is able to measure firm or soft touch, probably even one or two hands on the wheel. I am not so convinced that it is able to evaluate the intensity with which I put my hands on the wheel, it would mean that the reading would take place through an A / D converter, I think that the reading takes place in a purely digital way, or yes or no, one or zero ... But, the capacitive wheel has an integrated electronic card or, it is one or more connectors that connect to a card behind the dashboard. If there is no electronic card in the steering wheel, it is very likely that there is a wire connected to the capacitive sensor (or to several capacitive sensors), it would be in my opinion to intercept this connection. But it would be necessary either, the wiring diagram of the steering wheel or, to have one available for reverse engineering. |

There is a control unit inside the steering wheel. In MQB, there is 5H0959542A installed for capacitive steering.
You can also check the status of the touch detection in the live data of 19.
It shows the intensity of 3 sensors (values of 0 to 250 per sensor) and an overall, moderated touch status value (in my case, it can show "no touch detected", "light touch left and right detected", "strong touch left and right detected").
Yes, I tried that minutes ago to proof my point with that. So yes, it is intelligent and just shorting anything will not work.
I wonder if you know erwin? There you can download wiring diagrams of all vw cars.

Then in effect the reading takes place on analog values and converted via A/D to logic levels.
I have seen the erwin site, I did not understand if as a private I can download the manuals or if they are paid?

But forwarding that much detail into the Gateway will likely bring a lot of error-protection, so sending the same values over and over should trigger some plausibility check. For erwin you will need an subscripton for an hour, in that time, you can easily download all information as pdf and use them afterwards. |

Today I had the information that all the ID3s sold in Italy have the capacitive steering wheel as standard. At this point maybe something needs to be activated...
I checked the items in the various ECUs, in particular in 13 (adaptive cruise control) the "travel assist" item is indicated as not active (I don't know why as I have coded the A5 ECU as indicated and the travel assist is up and running ) and, the item "capacitive steering whell" is indicated as not fitted...
In the ECU A5, on the other hand, the KLR item is indicated as "not coded"...
What mean KLR ?

Post by ik4nmf on Nov 19, 2021 16:41:28 GMT
Ok KLR mean Kapazitives LenkRad i.e. capacitive steering wheel...looking at the current encoding that I entered as suggested by mencey i.e .: STG A5 TA mit VZE 00 08 30 2A 15 01 10 E4 16 24 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 byte 04 is set to 15 From another forum I found this pdf about ID4 but it should be the same thing:
It can be seen how to activate the capacitive steering wheel it is necessary to lead to 1 the second bit therefore, the byte that was set to 15 should be set to 1D, Correct me if I'm wrong...
In theory if the information I had is correct or that mine like the other id3 in Italy have the capacitive steering wheel already installed but not active as I purchased the car without travel assists, modifying the byte as I indicated should work...

You are right with the KLR translations (funny enough, this was Klima/Lüftungsregelung years ago).
You can check if your gateways apk "control unit for steering wheel touch recognition" is set to "dataset 2"

Further up in the long data post that I put comes the Travel Assist encoding with capacitive flywheel in an ID.4 is all the data, you also have to objectify Stg13

So, this is my current situation:
Thisi is the A5 control unit, as you can see KLR is "not coded", I could try to set the bit to 1 so it would be "coded"...What do you think about ?
This is the 13 control unit, as you can see travel assist is no active, I could try to set a "active" and, Capacitive steering wheel is "not mounted" , I could try to set as "mounted" what do you think about ?
I could try to do one encoding at a time, for example starting from the KLR in the A5 control unit, I would not want to get into trouble..

You can check if your gateways apk "control unit for steering wheel touch recognition" is set to "dataset 2" In which module do I find this entry ? |

Get used to backing up the control unit you are going to encode, so you can play whatever you want. If there are errors, reset the backup, erase all errors, turn off and on the car and recover factory settings

Post by ik4nmf on Nov 21, 2021 10:20:30 GMT
This of course I do...
I have a question:
does anyone who has an ID3 with travel assist installed from Volkswagen who could read the coding of the A5 and 13 control units? I would like to remove some doubts before proceeding

Yes I have an ID.3 1ST PLUS, but in the A5 and 13 module is there a lot of stuff in long coding? what do you want to see exactly?

Hi ID.3, if you have the travel assist factory installed, I would need the full hex strings of the A5 and 13 control unit.
it is strange that in the two images you entered, in the control unit A5 the KLR is not coded and, in the control unit 13 the capacitive steering wheel is not mounted and the travel assist deactivated.
Perhaps it is better understood by looking at the two hexadecimal strings.
Thanks in advance...

This is because I would like to understand if there are differences between the ID4 encodings posted by mencey and those of ID3. In theory they should be the same but it is better to check before making changes ... among other things I have had the confirmation that almost certainly my car has already installed the capacitive steering wheel, it seems that it is true that in Italy the ID3s sold already have it. , looking in the configurator is part of the accessories installed as standard.

Ok, but can you tell me where I can find this hexadecimal string, tell me where exactly went in the menus to find what you want? Yes for my ID.3 1 ST PLUS is original with the basic options.

How can you tell if you have the KLR capacitive steering wheel installed in your car?
How do I know if I have it installed but not configured?

change your configuration if you want to have travel assist, don't forget to back it up first.
