Steering wheel re-done today. As you know I had trouble getting it off last time, so I emailed Club500Italia as they take 500s apart all the time. They told me that all the steering wheels have the holes, but you have to take top and bottom cowling off to get to them.
I was looking in the wrong place, I thought they were further up the wheel at the back. The USA video on Youtube shows the holes in a different place, so their Airbags must be different.
Took off the cowling, pushed and fiddled about a flat bladed screwdriver and it popped off. Pictures attached.
Steering wheel is now straight.
Also sorted out the Start/Stop and Heated Rear Window that weren't working, all it was was a cable that is connected immediately behind the panel which is connected to the switches themselves had come out of the connection. Five minutes, and it's all working again.
As for my breaks binding problem. While I was lying on my back unscrewing the bottom cowling of the steering column I had a good look at the brake assembly and what a complicated bit of engineering it is too.
When I got the car back from the paint shop, the interior was covered in a layer of sanding dust, it was everywhere. I can only assume that when they took the old door off, they were doing bodywork before putting on the new one. I cleaned it up best I can, but the mechanism at the brake pedal is also a bit covered in dust. I've tried to dust it off and I've now sprayed WD40 all over the mechanism so time will tell.
I was going to change the brake pads today, but I'm going to see how it is now after WD40ing it all.
Fingers crossed.
Apart from changing the plugs to Iridium ones and fitting a new Air filter, all I have to do now is put in the new (second hand) Airbag ECU, and it should be all done.
