I've been an impatient putz!

Got my new Nappa and chrome steering wheel, watched the how-to video four times, had the instructions to hand.

Removed the battery negative and left for 10 mins.

First problem:

I cannot get the inner wheel and bag to undo. I put the flat headed tool into the holes and can't find a spring release. The tool goes in and I feel around. I push. Nothing. On either side.

What have I done wrong?

Second problem:

I give up. Reconnect battery. Start engine to check all is well.

And get this! Suspension failure.

Can't help with the first part (which video?), but second part is normal after battery disconnect.

Start car and turn steering wheel lock to lock, Christmas tree lights and messages should disappear, maybe also after a little drive. 

Have "RSW All Comms" in Hampshire - happy to help

Current Combustion Engine Transports:
Range Rover 2002 TD6 HSE Alveston Red, Sand Leather
Audi 2004 Cabriolet Sport 3.0 (Amulet Red)
Mazda Eunos 1990 (Brilliant Red)
MG Midget Mk 1 1962 (undergoing restoration) (to be Nightfire Red)

That's a relief.

It was the video on Powerful's website. The YouTube one. A man ain't truly been insulted until he stands buck naked in front of a woman and she didn't even notice. Or care.

i had the same issue doing my steering wheel fit this should help u

these pics may help u

Parts required.
1) Small 6-8 inch Allen head used to remove airbag or a thin blunted off screw driver
IMPORTANT! YOU MUST DISCONNECT THE ROVER BATTERY BEFORE starting this You want to be 90 degrees, perpendicular to the steering column. You want to push in the spring release to pop off the airbag. The photos below show the spring. Inside the steering wheel is a little "guide" that should help you go into the right direction

there is a nack to removing the air bag, i use a allen key just a bit smaller then the hole.as you push in the nack is to push down on the air bag at the end you are doing,it may not spring up first time so go on to the other side and do the same ..it will spring up..dont worry about the sus fault it will clear its self, done it on my car just the same.. V8 facelift Range Rover Autobiography 22" wheels.
1976 Harley Davidson Iron Head Sportster

Gents, as always, a massive thanks!

Can't do anything until next week, but i'll give it another try as soon as I can. A man ain't truly been insulted until he stands buck naked in front of a woman and she didn't even notice. Or care.

An update to this:

Got back early from our weekend to get my 110 fettled some more, so headed outside for Take 2.

Found the Allen key method more successful.

Had to call the father-in-law to bring round the correct Torx bit to get the wheel back off and onto the new one. Naturally, my RR was blocking my other cars...

And the end result. I'm really happy with it!

Thanks again for your help, chaps.
