Just wondering what the procedure is for removing the steering wheel controls, do you have to take the airbag off to get them off?
My experience of a similar problem on an '05 tourer Ex:
The previous owner has spilled something sticky in the steering wheel stereo controls, and although functional I wanted to remove the switch ***embly to clean it out.
I guess the right way is to remove the steering wheel complete and deal with it on the bench, but I have three problems with that: disconnecting the air bag (without it going off or throwing an £xpensive light on the dash), getting the wheel off its splines without a puller and the risk of a knackered clock spring.
Anyhow, I had a go with the wheel on the car.
There are two pozi screws accessible on each rear-side of the steering wheel through holes in the back of the wheel cover (two for the stereo switches and two for the cruise switches). Rotate the wheel so the holes are at twelve o'clock for best access.
These screws release the switch ***embly (note the access holes are smaller than the flanged screw heads, so although they can be undone, the screws can't be withdrawn through the back of the wheel -there is a significant risk they come adrift and end up rattling round the inside of the wheel!).
Unfortunately the connector for the switch ***embly is on an angled bracket that sits under the air bag. With the air bag in place I found it impossible to manoeuvre the switch into a position where it can be unplugged and withdrawn.
'No problem' I thought, 'I'll just remove the air bag screws and ease it forward quarter of an inch' (leaving it connected). Easier said than done! The T30 torx screws are easily accessible at the three and nine o'clock positions through access holes in the side of the wheel, however they have some
serious thread lock on them!
I managed to get quarter of a turn out of each of the screws (successfully loosening the air bag module, but not enough to remove my switches) but that is as far as I dared go. The on-going mega-tightness of the screws meant they got pretty mashed. I had to quit whist there was enough bite left to get them back in! If I'd carried on I'd have stripped the heads and had a rattling air bag. Drilling them out might be an option, but I'd want the wheel off after that to hoover out any swarf (and as mentioned earlier I want to avoid removing the wheel!)
In summary: a disappointing failure :-(
I'll live with the sticky switches for now. If anyone else has a go, I'd recommend using the best quality torx driver you can find (probably on a ratchet bar rather than a screw driver) and be prepared for them being too tight to shift.
