The steering wheel stereo volume control on my 2008 Cooper S with 3 spoke steering wheel was worn so I bought used buttons that were in perfect condition for $20 (both sides), popped out the circular "toggle button" and put in a newer one.

Its quite simple. My advice is take off the steering wheel and bring it into your house to let it warm up for a few hours so the plastic isn't as brittle. (scrub that nasty *** steering wheel with some warm soap and water while your at it...much black grime came off of mine).

1. Disconnect battery!!!!!!!!!!!!!!!!!! Cause you about to,

2. Remove the airbag (see vids on Youtube on how to). VERY easy.

3. Remove steering wheel center nut (15mm?) and bring'er inside.

4. If you have paddle shifters move them by loosening Torx screw (T25?) holding them in place and delicately move them to the side. Wires will still be connected. This is for access to the screw that holds the entire grey plastic control in place and for better access for cleaning...ya dirty mutt!

One on each side.



5. Another Torx screw (T22?) holds each of the control units to the steering wheel from behind.



6. Gently pry out the control. See the plastic "anchors" that keep it in place?



You can change entire control or just the round button(s). I bough a replacement button with a scratched up housing so I only wanted the round radio volume / scan button.

7. If you want to change just the round button(s), you need to open the grey control housing via the tabs on the periphery /sides of the control. Very easy. You can see those tabs in the pic above. Just pry and pull the 2 sections (grey top housing and black circuit board) apart so that you have access to the underside of the round button.

The round button is held in by 2 tiny black tabs. See them exposed after being taken apart:



You can just push the button out from the back to pop it out, but I suggest you delicately pry the tab away on one side and then push out the replacement button from the controls, like this:



Here is the underside of the button:



8. Push the new round button into place.

New round button in the original housing.



9. Put it all back together.

 

Good pictures and write up!

 

Glad it could help you.

 

Any idea how to add these buttons to a car that doesn’t have them. I found a complete steering wheel/airbag for sale.

What at all is needed. I think there is a remote computer box and the turn signal switch is different and needed.

Anyone have any more information?

 

No idea.

 

Forgive the necropost, but if anyone still following this has any idea on where we can buy buttons without having to buy a whole honkin' steering wheel, I would LOVE to be able to do that. Every steering wheel I find remotely in my price range has buttons that look almost as bad as mine!

 

I found used buttons, but I don't recall from where. More than likely EBay.

 

Thank you! So far only found silver ones on ebay, and only one side. Mine are black. Think the silver ones are interchangeable? I don't think putting silver in my otherwise black steering wheel would look bad at all, because the center circle is the silver color, and the tachometer is silver too!

 

Send some pics of your buttons and wheel.

 

I know this is a very old post, but figured I'd reply for the people who search the same thing as I did and got brought here. I found brand new buttons for cheap on Ali Express. It takes a little longer to arrive but they are great. There a lot of options for the different years and which buttons you need.

 

Thanks for the info!
