Have you checked for air leaks around the filter box? Make sure everything is well connected - pipes, box, sensors etc.

Sometimes if the BSI sleep procedure isn't followed (ie. the BSI is left to rest for a few minutes before disconnecting sensors or the battery), the disconnection will register as a fault. This often happens - I'm guilty of doing it myself (which is naughty, I should know better....). It shouldn't cause you any major issues, and should go away of it's own accord.

I'd recommend getting the Lexia diagnostics done just in case - I'd happily offer to help, but Co. Durham is a little too far for me. York is pretty much my "area boundary"
