BMW 116D (2016) Power Problem

Can’t see the dme would reduce power due to low tyre pressure, but that will cause drag if it’s that low.
Starting point is obviously tyre pressure first and then car will need plugging in to see if any codes logged and see what live data reveals
 
You threw me with 1.7psi as that is totally flat and would cause drag, so it was 1.7bar and now corrected to 2.1bar. I still find it highly unlikely the tyre pressure would cause power reduction by the dme. I had a puncture on my 330d I drive warned me about it but there was no power reduction other than my right foot.
I think it’s more likely whatever was causing it has coincidentally cleared itself, time will tell I suppose.
