Pop the bonnet and disconnect the negative terminal from the battery, then disconnect the positive terminal.
Allow the car to sit for at least 20 minutes before you proceed further to allow residual electrical charge to dissipate.
Locate the small holes on both sides of the back of the steering wheel.
Place a 3-mm hex-head key into one of the holes and push it in firmly to pop out the airbag from one side of the steering wheel.
Repeat the process on the other side of the steering wheel until the airbag falls out of the steering wheel.
Locate the wiring harnesses leading into the back of the steering wheel.
Use a flathead screwdriver to pry the protective cover off the back of the airbag harnesses and then push the clip in to pull the harnesses off the airbag.
Place the airbag to one side face up in a safe place.
Many thanks for the advice.
I followed thye instructions given to the letter and also the Haynes manual method using a small screw driver..
Neither way would the springs move to release/airbag unit.
I can see the curled top of the spring ? using a mirror and its really tantilising as Iam becoming an expert at removing the surrounding panels for easy access. .
Perhaps I pushing in the wrong direct but I have tried variants.
Sorry to be a pain but I would like to solve this problem.
