Not sure if this helps but the Audi system, which I believe is exact the same on VW, Seat & Skoda, will park wrong side but only if you indicate into the side the spaces are on when approaching.

Only mention this because it wasn't documented in my manual and the sales folks had no idea.

In practice i find it's too slow to use, doesn't account for high kerbs with its preprogrammed trajectory (not user adjustable), happily dry steers and can be fooled by a squinty parked car in front of the space. Not a fan yet, but has potential, and if it means ill come back to less dings on the bumpers I'm all for mandating its use ;-)

A better system today is the Toyota reverse parking assist with guidelines overlaid which adjust to your trajectory based on current steering input and speed.

Thanks for the tip about indicating - it is a VW Golf Plus. What has surprised me is how good it is at parking between badly parked SUVs on the side of our street that doesn't really have much of a kerb. On a few occasions I've actually walked round the car and wondered what it was using as a reference point for parking - because it definitely wasn't the kerb or the cars in front/behind. Of course, maybe I'm just lucky in picking the starting point.
