I am planning to change the Steering Wheel Stalks assembly in an Audi A5 2018 Sportback (B9). Does any one know what coding might be needed when a new Steering Wheel Stalk assembly is installed. The new cars don't come with separate Slip ring and stalks. Everything is a single unit. Is the G85 Steering Wheel sensor calibration routine the same in the B9 cars?

Can I ask why the change is needed / what you are trying to retrofit?

I am trying to retrofit a Heated Steering Wheel. It's no longer an available option in the UK on the 2018 A5 Sportbacks. It was available until last year and is still available in many countries.

I have the required new Steering Wheel. But need to buy a new Steering Wheel stalk assembly.
And since I need to install a new Steering Wheel stalk assembly for the Heated function, I thought I might as well get one that comes with the ALA button.

So when I install the new Steering wheel stalk assembly that will need to be coded to the car. So as a basic step I guess the Steering wheel sensor will need calibration. Is the procedure on the B9 cars the same?

Good stuff, got to love a heated wheel! :)

Well I am not sure on the answers to your questions but if you are in or around London I can assist with any of the needed works if VCDS will not complete the job. I have online access should SVM or CP be needed.

Is someone prepared to tell me what I need to do if only VCDS is required? Also is the VIN number stored in the Steering Wheel Stalk assembly controller? I.e. Do I need to buy a new one or will a used one also work?

Having just seen the A Map and B Map of the Steering Wheel Stalk, I can see that the car's VIN number is indeed stored in it. However the part itself has no coding possible. So how does one go about coding a new Steering Wheel Stalk to the car when the part doesn't accept coding? Is there even a concept of a module in the car that stores the car's Vehicle Order? Or is the Vehicle Order only stored online at VW HQ? This confirms that I can't use a Used part unless there is a way to change the VIN on that part?

Does the part have Adaptation channels? VW are moving over to using only adaptation and no coding, so worth checking I think.

The A Map shows some Adaptation channels. But the only one of note is the Steering Wheel Heater Temperature setting which is known. However the Block map shows a lot of values that the control has either learnt by itself, were pushed to it or were coded in. But if the part itself can't be coded how did those values get into the control module. That's my question.

I'm keen to understand how the car now "knows" it has a Heated Steering Wheel when previously it didn't have one. In older cars, this module 16 was codeable and that made sense. Now this module isn't codeable so clearly other modules will need to be coded to make the Heated Steering Wheel function work? So does the simple fact of installing and powering the new control module allow for the Heating function to work because the new module is pre-coded to listen to the BUS message that the new Heated Steering Wheel will put out? I know there is an additional power line to the Steering Wheel control depending on whether the car has a Heated Wheel or not.

What is also strange is I have seen references to Steering Wheel Heater in Modules 09 and 19 in a maps and b maps from cars without the Heated Steering Wheel. Yet the car with the Heated Wheel from the factory has absolutely none of those references!
