So my genuine parts VW Polo 6r front and rear PDC / OPS arrived today. Here it is in all it's glory with my RossTech VCDS for coding. Looks pretty easy, soldered into the cambus at the steering wheel, new button on the dash, drill a few holes and hey presto.

I'm quite excited and I'm going to get the sensors colour coded tonight !
And don't ask me why I want front and rear parking sensors on such a small car....I just do ! and I like a little project !
