I’ve got an interesting problem with the sink tap in my 2021 MP. The first half a dozen or so times you use it the tap works just fine, but then the next time it doesn’t work and there is no pump sound. The pump hasn’t been running long on any occasion so hasn’t overheated. I checked the fuse and it was fine, and on reinstalling the fuse the tap worked again, for the first few times! Now the really interesting bit is that I then noticed that when the tap isn’t working, the main light in the accommodation area also doesn’t work - you can’t switch it on manually with the switch. I then turned the light on using the phone app and the light worked, and the tap started working again. I now use this trick every time it happens and it always works. I am guessing there is a problem with the MBAC control unit but was just wondering whether anybody else has experienced a similar issue.
