1.9 Tdi poor fuel cosumption

[PD_Paul]

Car has done 150,000 miles and is used as a taxi.  Fuel consumption is poor even on a long run and this is based on owning an Octavia with the same engine previously.

 

I have checked all the usual things such as tyre pressures, wheel alignment, binding brakes and all filters have been recently changed.  I visited fellow forum member Martin (Gizmo) last weekend and have some readings below from VCDS.

 

Car starts and drives ok, but I would appreciate it if you can see anything obvious which might explain the poor fuel consumption and how I can rectify it.
