Hi guys,
has anyone been able to retrofit the auto hill hold button. I hooked everything up according to the instructions but the button lights up when pressed then turns right off.
what am I missing?

Did you code the car for the feature? I'm fairly certain it's not just plug and play.

The auto hold button came with a kit that had a code box that I plugged into the OBD port to code everything.
I actually don’t think the box code the car correctly.
do you know how to code this particular feature?

Did you have the bonnet (hood) open when you did the coding. If not it will not work

Lex330

Yes,
I had the hood open. When I plugged the coding tool into the OBD port, the box is supposed to light up green until the coding is completed. The green light started flashing then is turned off. The green light was never solid green as it was supposed to be when the coding was executed.

Any other suggestions for the auto hold button?

Find someone local with VCDS and see if they can code it for you.

Ok, thanks

Hey guys, I took my 2019 A6 c8 to Audi and they told me I can’t do a retrofit for the Auto Hill Hold button.
does anyone know if that is true?
also has anyone done a heated steering wheel retrofit?

I had NGP do the installation for me, along with the Auto Park. Auto Park works fine but the Auto Hold is not. Might be a wrong pin connection as the programming looked okay.
They will work on it until it "Holds" as normal.
