Swapping Heated Steering wheel to Flat Bottom

[SeatonS4]

I have done a bunch of searching but found nothing definitive so figured I would ask the fine folks here.

Picked up an alcantara flat bottom wheel from Alex @ Europrice to swap out my current heated round version. Now on startup I get an error relating to the heated steering wheel. It goes away with no residual lights or warning, but just wondering if there was a way to code this out with VCDS?

Look for threads on retrofitting a heated steering wheel to B9 and see what coding change they make to enable the function. Then just reverse that. Alex might also know as well.

Wait so your old wheel was heated and the new one is as well? If so, I'd be surprised if you had to code anything...wouldn't it just be plug and play?

Some folks are saying that you have to swap a bunch of parts in the steering column. I was hoping you could just code it out.

Sent Alex an email to see if he knows. Will let folks know what he says.

Have most folks gotten their cars without the heating package so it isn’t an issue with a swap or maybe there isn’t a huge demand for wheel swaps in this model??

No. From what I know, there isn’t a flat bottom wheel that is heated from Audi.

I was just confused because you still have the heated wheel button in the picture you posted. I'm assuming you just used your previous buttons and airbag though? I have a B9.5 RS5 and have a flat bottom steering wheel coming (not heated) to replace my round heated wheel. I'm wondering if I'm going to get the same error message?

Yeah. Sorry about that. Yes I just moved over the controls since I had to pull them out to put the Urus shift paddles on. Everything swapped over nicely and once you get the airbag technique right it is pretty simple. If you have a heated wheel now, I assume you will get the same error. Hopefully someone knows the answer for how to correct it. And equally hopeful that it doesn’t take a bunch of new parts and is a simple fix.

What does the error say?

[SeatonS4]

I can get it this afternoon. Daughter took the car to school today. I will post up what it does and how it disappears.

I thought the biggest difference would be the new capacitive hands-on detection as compared to the older steering wheel input detection. Have you tried the new wheel with active lane assist/lane departure?

Edit: Just saw Alex's post that flat-bottoms with HoD are available.

Here is the “error” that comes up during startup.

It goes away and leaves nothing on the dash. Been chatting with Alex and the only way that he knows to get rid of it is to swap the steering wheel control module that has the stalks attached and a different slip ring.

I guess it is something new and I will have to learn to ignore it.

Yeah, if it's hard built into the J527 and not a long coding toggle you can just flip to tell the J527 "stop trying to look for a connected wheel heater circuit", that's about the best you can do. I knew it took a new unit to add the heating support, but wasn't sure if the heating operation could just be coded disabled.

Most likely the J527 is detecting an open circuit for the Z36 steering wheel heater grid. You could throw a resister across those two lines just so it sees a complete circuit. Profile still says 2011 S4; I presume this is a B9.0 vehicle. Here we see the heated wheel with the 2-pin plug at the 8 o'clock position from center that plugs into the heater circuit 2-pin plug on the coil spring.

I'd get another one of those plugs and wire a 10kΩ 0.25W resistor (you can get 10 for a $1.50) and plug that in and see if that's enough for the J527 to be happy. If it did turn the circuit on for whatever reason, the resistance would keep it at only 0.02W flow. Could even tape it to the steering wheel metal plate as a heat sink if you're really worried.

But seems a lot easier than dealing with a whole new J527. But I have no idea what the part number on that plug is; you'd need to look at your old wheel.

That would be an interesting fix. It makes sense that it would detect the heating element. I will pull the old wheel out of the box and see if I can find any part numbers or some identifying markings on the plug.

I retrofitted a heated wheel to my car myself so I know what is involved. Your car has the Heated wheel steering stalks. If you want to get rid of the error, the only way to do that is to find one with the same features as you currently have but without the steering heating PR code 1XP. You cannot code this out, because the coding is fixed based on the part number of the steering stalks. If you read the part number of your steering module from VCDS or ODB11, then we can go from there.
I knew I wanted to change the stalks to include the Heating feature, so I took the opportunity to get one that also had the ALA button PR 6I1 as it was another feature I wanted to code in. So now is the time to decide if you want other features on that steering stalks module.
P.S. Besides that initial error and the error stored in the memory, there is nothing else that will show up in the car.

If you are going down the route of adding a resistor, then first check the resistance of the actual heating wheel heating element. Because if the detected resistance is out of spec then it might not work. Also hope you turned the Heating function OFF on the old wheel before you took it out. Otherwise that function will constantly be turned on, with no way to turn it off. You definitely don't want that resistor going hot under the airbag!

[Pizdets-b5]

with every car i have come across you can code out different features. yours shouldnt be any different

also if youre interested I have some alcantara airbag covers to replace that plastic stock one. if interested shoot me a pm

[bruce_miranda]

That was true in previous generations. Now if you look at Module 16 I.e. Steering Wheel that has absolutely no coding features. The coding is hardcoded to the part number. And every part number is associated with the different functions. And there is no separate clockspring too any more, its all one unit, the stalks and the clock spring.

Hello, was anyone able to figure this out. I just installed a CF Non Heated wheel in my RS5 and I am getting the same error at start up. Just wondering if this has been solved.
