Hi,

Just wondering if there's a guide for replacing the ignition switch on the Fabia Mk 2.

I believe that this is the part number: Part number 4B0 905 849 and it is shown below.

I presume there's no immo built into this/key coding required; this is just switch contacts for ignition on/off and crank?

Thanks in advance.

I've changed these a few times. They are just a contact switch, the immobiliser is in the lock. Don't buy the cheapest no name ones, they can fail again quickly. Meyle or original skoda have both been good. Main steps are:

Remove steering wheel airbag

Remove steering wheel - undo centre nut, pull..!

Remove upper and lower steering shrouds, unplug the cable harness from left hand side, see item 1

There's then a grub screw to remove and the ignition switch comes out to the left and can be replaced. No need to touch the ignition lock barrel or shear screws

Excellent - thanks :-)

I think it's actually the rear hatch harness but it is all good info.
