Lost of power
Hi I have a 2007 D5 xc90 and I struggle to accelerate, I have recently had the cylinder head changed with new timing belt and pump with the DPF cleaned out. It came up on the diagnostic set as exhaust temp sensor & pressure sensor. These were both changed the pressure sensor admittedly was a cheap version, but Im still struggling to get it moving. Its now saying MAF sensor pressure sensor. Do I go for broke and buy new MAF sensor (can it be cleaned) pressure sensor and DPF. Any advice will be greatly appreciated.

Stop throwing parts at it and get a proper diagnosis by a competent VIDA-equipped mechanic.

Diagnostic scanners can only give you an indication of what the computer systems are doing. A fault code for the MAF, for instance, may mean that it has failed or it may mean there is a wiring fault or there may be other issues that has been interpreted by the modules as a MAF fault.
The diagnosis process is more involved than just reading codes and swapping parts. I am sure that the AA mechanic is doing his best but you need the services of a competent, knowlegable, mechanic with the right equipment to track down the issue(s).

As above, it looks like your mechanic is changing random parts. Ask here for a garage recommended near your place, that may help. And rather get used parts from ebay or breakers, genuine ones.
