Its a bit of a pain to explain but here goes. Remove the cowling then get a mirror and look on the back of the air bag and you will see some spring clips, you have to push the clips in one at a time then move on to the next on. Once all move you can lift off the air bag then you will see the bolt holding the wheel on. I suggest when pushing the spring clips make sure the corner of the air bag is at 1 oclock then spin the wheel till the next corner of the air bag is at the 1 oclock position.
SOrry but i know thats sounds crap, easier to show than to explain..
is this a dumb question guys??? i hear youre supposed to disconnect the battery before messing with the steering wheel and airbag on mk6 and 7`s to prevent them going off by accident,,,is this true or false ? i heard a tale of one going off on someone and breaking his arm
