HELP! TT Steering Wheel Gear Shift Paddles and Radio Controls NOT WORKING!

[D0lphinGrey]

My Tiptronic B7 has the multifunction steering wheel with built in gear shift paddles and scroll controls for the RNSE. I'm replacing it with a new MKII TT Steering wheel with factory gear shift paddles and radio controls.

I followed audinoob's diagram -
-using original A4 B7 harness,
-replaced original A4's horn pin with TT's larger horn pin
-replaced/modified original A4's single grounding pin with two larger grounding pins from TT harness.

With TT steering wheel and airbag now fitted. The wheel feels great and the horn is working. But,
*Gear shift paddles - NOT WORKING
*Background lighting for the controls - NOT WORKING
*Scroll buttons for track and volumn - NOT WORKING
*Dash Airbag light ON (obviously)

From all the steering wheel swap threads I've read and as I understand, I do not need to reprogram with vagcom. It should be plug and play. Am I right
? So what could be the problem?

Thanks

you do need to vag-com to enable the paddles, and I think it is not grounded properly. Check again

^you do need to VAG it and if there are no lights you wired the harness wrong. Get power before you worry about the functions.

Thanks. I will find someone who can vagcom it for me.

I did split the ground to each tab. Does it matter which pin to which tab?

Are airbag light and background lighting of the controls all to do with grounding?

What about scroll controls?

Thanks. But what do you mean by wired the harness wrong?

[D0lphinGrey]

Ok. On the original A4 harness, the single wire with a tiny pin is for the horn, correct? I replaced that with a larger pin for the larger horn tab on the TT airbag.

There is also a larger pin (on A4 harness) with two wires attached to it, thats the grounding, correct? I splited these two wires and attached two individual pins to each wire. And these are plugged onto the two grounding tabs on the TT airbag. Have I missed anything?

[Sharkfin]

It's hard for me to understand how you did it through words, make sure you unwrapped the tape and got the right wire

Hey Dolphin, I have Vag com if you need to use it. I wouldn't have a clue how to recode these items but you can definitely use it. Let me know

its hard to visialize but look at audinoobs diagram again. Look at the grounds closely and see if there is any other way to split the wires. I really think there is something wrong with how its grounded and think you should focus on that. Oh and yes all the multifunctions on the wheel will work.

Thanks Nico. You're back in Sydney now? I will contact you once I find out what to do exactly with recoding.

some pics of my modified A4 harness on the TT airbag.

Does anyone know the actually coding for this? Thanks

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.


go to the steering wheel module, and go to recode, on the high head ross-tech cable with the new software, it will pop up a coding menu on the side so whatever the code that in your car at the moment, just +1 to the third # from the left. my original code was 02021, the new code 02121. you can do this with the old ross tech software and the ebay cable

Thanks. But this is using the TT harness. Correct me if I'm wrong but you can also use the A4 harness without reassigning any wires? And since I have already modified the grounding pins (taken from TT harness) on my A4 harness, Im hoping I can some how make it work first.

Also for vagcom recoding, ist the same whether I use the A4 harness or TT harness?

What's the latest on this? Did you get it all working yet?

sell me ur old wheel with the paddles :P

ya the vag code is the same, ur fine then with ur harness then, i did a similar thing with the a4 harness

All worked out fine (lights and radio controls).[up] audinoob06's diagrams were spot on. The reason mine didn't work the first time was I splited the grounding wires (theres two) individually. The correct way to do it is to extend both wires (not individually) and create a Y-connection (as per audinoob06's diagram).

Haven't got the airbag fitted yet, as I'm missing one of the two bolts that secure the airbag from the back of steering wheel. It has to come from Germany, a 10AUD part!

[D0lphinGrey]

sell me ur old wheel with the paddles :P

Sure if you don't mind paying postage from Sydney. Shoot me a pm.[:D]

Thanks. Yes the A4 harness works fine.[up] I think it's much simpler and easier than modifying the TT harness.

[Dangler]

I'm glad everything work out! How do you like the steering wheel?

I love having the option to use the paddles.

[bmc333]

Be sure to post up pics of the finished product - I'm still considering doing this mod myself - love the TT wheel!

[scoobycarolan]

pic it up!

Ok finally picked up the bolts from dealer today (took them 1 month! They got the wrong part the first time, ordered the "short" bolt which was for MK1 TT.) and installed the airbag. Everything looks great. Some good news and bad news.

Good news
- all the steering wheel controls are working properly now, scroll buttons, red background lighting and horn.
- gearshift paddles are working WITHOUT vagcom recoding! I'm confused but not complaining.[:d]

Bad news
- Airbag light still ON[confused] Need vagcom? Faulty airbag?

[D0lphinGrey]

Oh another question, how much "gap" should there be between the airbag and steering wheel looking from the top? Mine has about half a centimetre gap, not sure if its right?

[Sharkfin]

Clear the airbag codes, if it is wired correctly (which it seems it is), it will not come back on. Or you can continue to drive it and it will go off eventually

Thanks. How long does it take to clear by itself?

[Sharkfin]

I've heard 100 miles at the most, but I don't know for sure
