Thanks for the update. Didn’t think the bathroom light switch ever made it in to production.
Sorry to hear about your niggles. If the step doesn’t play ball you’ll need to unplug the blue connector underneath the passenger side footwell. Before you do this though, ensure the red switch is off. Unplug the blue connector for a minute then plug it back in. This resets the “kfg” brain which controls certain things, like the step. Unfortunately the step issue is well known and VW are trying (and failing currently) to fix this. Mines been ok so far in 10 months of ownership.
