BMW STEERING SLIPRING REPLACEMENT

Not much to be said why I am replacing the slipring, upon turning the steering wheel I heard a snap, and lost all controls on the steering wheel, including horn and airbag. It was evident that the slipring failed miserably. I bought a new one from dealership as am not fond of puting used parts that have mechanical movement on my car.

First and foremost, disconnect the battery negative terminal.

Reposition the steering wheel to its most outward/upper position, to make things easier.

Remove the airbag:

1. Insert a flathead screwdriver at the 2 openings behind the steering wheel and slightly push the screwdriver until you spot the 2 airbag retaining springs. The screwdriver should be set horizontally with a slight angle upwards, and closer to the steering wheel rather than the dash. Once you find the spring on each side, push it and with the other hand, gently pry the airbag out.

Disconnect the 2 plugs from the airbag. There are locking plugs, so you need to use a flathead screwdriver to pop the lock on each plug in order to pull it out without breaking anything

1. Retaining springs mentioned above

2. Disconnect all plugs from the slipring

3. Remove the 16mm bolt that secures the steering wheel on the shaft

Note the alignment mark on the steering wheel and on the shaft, this is to be able to place the steering wheel to the correct position

Once the steering wheel is out, you will see the slipring with the stalks attached on it:

In order to remove it, the upper and lower steering shaft covers must be lifted slighlty. There is 1 plastic philips screw on the top cover and one LONG push/lock pin on the bottom cover. Remove both

Bottom push/lock pin:

Upper plastic philips screw

After removing them, gently separate the two covers. You will expose 4 T25 screws. Remove them. (Picture is with the new slipring attached)

Pull the slipring a bit and disconnect the indicator, wipers and steering control plugs

1. Plugs to disconnect

2. Remove indicator and wiper stalks by pushing the 2 lock tabs and pulling them away from the slipring. They will slide out easily.

Open the new slipring :)

Slide the 2 stalks back in place and make sure they are locked (characteristic sound of the plastic locking tabs)

Reconnect all 3 plugs on the back of the slipring, screw the 4 T25 screws and close upper and lower steering wheel covers. Replace the plastic screw and lock pin if damaged.

1. Snap the red plastic by pulling it away from the slipring. This is installed from factory to prevent accidental turning of the slipring messing everything. This is an extra safety as the slipring still cannot turn freely due to that spring on its bottom. The slipring is allowed to move only when the steering wheel is installed, which basically pushes the spring downwards.

This is the new slipring installed, with the covers back in place

Insert the steering wheel back - aligned - reconnect all plugs, screw the 16mm bolt back and lastly, plug-in the 2 airbag plugs, making sure they are locked too.

Put the airbag on the steering wheel as pictured and push it in until it locks in place.

Reconnect battery and start the car. Obviously the airbag light is still on as it needs equipment to be turned off. Verify all other steering wheel controls work including indicator and wiper functions

Old slipring, the problem is apparent:
