I bought the latest "6Q0" variant today, parts guy said "fit with pedal pressed down you need to hear/feel two clicks" - this is the second time I've done this job on this car, so changed switch - no brake lights! Switch plunger seemed to be solid, took switch off, now plunger is free to move again, checked pin1 > pin4 with plunger "out" and plunger "in" both times O/C!! Anyway, took rear clusters off and checked them = okay, had a look at circuit diagram, feed comes from large fuse that also feeds lights etc, other lights okay, refit rear light clusters, refit new switch again with pedal down, brake lights work now?? Now I have read the Leon thread and see that others have had some issues fitting these new switches. I'm just writing this in case it helps someone else when they do this job.
