I changed my ignition switch to new unit for fixing power issues. Unfortunately replacement didn't fix the power issue and I even ordered wrong ignition switch to my car.
Anyway, I took some photos where you can see the differences between early and late ignition switches.
Part numbers for ignition switches are A124 462 03 93 replaced by A202 545 01 04
(late type ignition switch) and early type A124 462 02 93 replaced by A202 545 02 04.
Main two differences are amount of pins and length so they are not interchangeable to each other.
Here are the pics.


Left one is late type ignition switch.
Hope you find useful for this small info. I have more pics if needed.
