Installing a TTRS Steering Wheel into a B7 Audi RS4
The existing Airbag cannot be used with this install – they are totally different. You have to use the one that comes with
the shipment.
Equipment Needed:
· 10mm box or open end wrench
· Small thin flat blade screw driver
· Torx T30 bit
· Triple square ZXN12 bit (I got mine from Amazon VIM XZN400
Triple Square Drive Set)
· Blue Lock Tight
· VAGCOMis not needed
- everything is plug and play
· New tabs for the TTRS steering wheel (Audi Part Number (x2)
8J0 419 732 6PS - Pad
Time:
European automotive shop should be able to do the install in 30 minutes.
I did it under an hour easily and I was taking pictures
Basic installation procedure:
1. Disconnect the battery with a 10mm box
or open end wrench. (This is a safety precaution – others have done it without
this procedure but not me (and I worked on nukes for four years in the Air
Force). Remove the plastic cover and then use the wrench to loosen the nut on
the connector and slip the connector off the terminal. Do not close the trunk
till you have reattached the battery cable. Note you can wait on this and
disconnect the battery after you have rotated the wheel and removed the bolts
for the airbag (step 3) and rotated the wheel straight – This prevents the
initial warning that comes on after you restart the car.
2. Using a small thin flat blade screw driver and pry the
two torx covers off the rear of the steering wheel.
Here is what the tab looks like removed. You do not reuse
these with the TTRS wheel.
3. Using your T 30 Torx socket and loosen the bolts at the
rear of the steering wheel. These hold the airbag into the wheel. The
airbag will side right out of the old steering wheel and you will undo the
large yellow plug and black small plug. You can see the orange sliding lock on
the yellow connector – you slide that toward yourself to unlock it. Remove
stock airbag completely. On the black connector there is a tab that one will
press that releases the opposite side of the connector
4. Turn the steering wheel till it the wheels are pointed
straight ahead. Using the XZN12 triple
square bit on an extension with a larger ratchet or breaker bar remove the
center nut.
5. Slide stock
steering wheel off.
6. Using the T30 Torx socket remove the airbag from the
new TTRS wheel and disconnect theblack
connectors.
7. Slide new steering wheel on the same orientation of the
old steering wheel. (wheel straight ahead is the best way to start)
8. Put a dab of Blue Lock tight on the center bolt and
start threading by hand. Using the triple square bit tighten to a high torque.
9. Bring new airbag up to steering wheel and plug the
large yellow plug in till you hear a click to indicate that it is locked and
the small black plug in. (slide black plug into holder)
10. Slide airbag into steering wheel and using your Torx driver tighten the airbag into
plate. (medium torque, do not strip)
Attach
the new two new tabs (covers for the torx bolt) for the TTRS steering wheel
Go
for a test drive and enjoy.
Occasionally people have reported that a
warning light is present concerning the
angle sensor, however this will almost always go away on its own after a day or
so, depending on how much you drive – mine went out in less than a few minutes.
No coding is required via VAG-COM.
