Not plug & play but a very easy retrofit, you need to move three wires and file lightly the connector.
Another user explaining what needs to be done.
OK, here's the procedure to rewire the harness for the TT MKII MFSW. The harness has part # 8J0 971 589 B.
MAKE SURE TO DISCONNECT THE BATTERY BEFORE DOING ANY WORK WITH THE AIRBAG!
The 12 pin plug connector (yellow) on the TT MKII harness needs to have three of its wires re-assigned. Open the cover on the back of the harness plug. Looking at the plug connector from behind as if you were going to plug it in, there are 2 rows of slots, which we will number
1-2-3-4-5-6
7-8-9-10-11-12
3 through 6 are for the airbag - DO NOT TOUCH!
7 = Brown
8 = Yellow (horn)
9 = Purple
10 = Red
1, 2, 11, 12 are empty.
Push out the purple lock in the harness and then release the appropriate wire to be re-assigned.
You need to move the following wires:
move the Brown wire from 7 >to> 1
move the Yellow wire from 8 >to> 2
move the Red wire from 10 >to> 8
All MFSW controls including the horn should now work.
You may also need to trim the tabs from the sides of the plug to be able to insert into the S/C ring socket. You'll know what I mean when you see it.
Good luck!
Please note that these could easily be removed with an hairdryer/heatgun.
This steering wheel/airbag combo is 1900$usd brand new.
