Thread: Cruise Control stopped working

Thanks. I don't have radio control buttons on my steering wheel - just cruise control. But another thing worth considering.

Below is a the minute YouTube video as to how to remove the steering wheel on a 3. It is pretty good.

Myself, I remove the negative battery cable rather than the positive, about the only quibble I had on the whole video.

The video shows you how to remove the airbag, the trickiest part of the whole removal process. The steering wheel being removed is I figure close to the one you have - no radio buttons, just the horn buttons; also no cruise, but you have that.

I also had issues with cruise-control operation. The lower button would sometimes fail to resume or disengage cruise. The upper button functioned as normal.

I settled on replacing the switch pack and purchased a second-hand wheel from TRS in Adelaide. This way I got to replace my sun-damaged wheel and add audio and phone controls as well. The new wheel also looks to have a vibration damper, which my old wheel didn't have.

Resistances on the new switch packs.



The old pack displayed the same values, but I assume it is just having a 'good' day. Only time will tell if I've fixed the problem permanently.

I too am having intermittent problems with steering wheel controls lately(RRS 2006)
Started with radio controls getting muddled. Now Im having problems with the cruise control. The cruise sometimes will not respond to the + command.
Since both switch packs are affected Im hedging towards the rotary slip ring (clockspring) assembly being worn out.
Will try a hard reboot before I commit to a $200 slipring
Anyone solved these issues by replacing the slipring?

Hi Grappler,
I had similar problem with the cruise control buttons and was thinking clock spring issue. Had my mechanic investigate, clock spring OK, he then looked at the switch pack (buttons) and solved the problem by cleaning the contacts. All good now for the last 9mths.

Finally committed to changing out the slip ribbon assembly (clock-spring rotary assembly)
Bought one on eBay from UK for about $100 all up
Being aware of the hazards of working on the airbag I disconnected the battery and shorted the battery cables for 2 minutes.
With the steering centred, straight ahead, the airbag assembly was released with a piece of fence wire about 100mm long a with a 5mm hook on one end. I positioned my self the the side, out of line of fire when working on the bag assembly
The rest is pretty straight forward. Carefully remove the connectors, note cable routing, release the steering wheel bolt and remove the wheel noting the witness marks on the spline.
The 2 torx screw underneath, holding the lower cowling were removed and the cowlings (top and bottom) eased away to access removal of the 4 phillips screws holding the rotary assembly.
Remove the remaining connectors and remove the rotary assembly
Replacement is generally the reverse of the above, but consider the following.
The new unit has a ring pull to keep the unit calibrated to straight ahead and requires snapping off, just before the steering wheel goes back on
Check witness marks on steering wheel/spline are aligned and the spigot engages the hole in the wheel. Torque steering wheel bolt to 63 NM
Double check connectors and cable routing and retention. All the connectors are uniquely mated so you cant mix them up
The airbag assembly is pushed on and will snap into place. Take care not to pinch any cables.
Reconnect battery.

Tested the function of the switches. All functions now work including cruise control and radio controls that had previously become unreliable
