I had a spare MAF in the garage, so changed it. Showed around 35kg/h while idling.
No change to issue though, graph below showing when I booted it and it went into limp mode.
I forgot to add the EGR to it.
Air filter is about a year / 6000 miles old and is a little discoloured but not dirty. This issue pre-dates the air filter though!
@ Davebb - I don't see an option for requested MAP??
Same as before though - 1st boot after engine warm, limp.
Shutdown / restart a few miles later, then no further issues for the next 5 miles home. Surely air filter and most sensors won't care much about temperature / run-time, but sticking mechanical VNT could?
I'll do another graph tomorrow from cold. Can only add 5 parameters, so which ?
