Yes , this is a specialist job , a lot of know how needed ... They Probably have failed to do the last part of the job , ie set the fuel pump timing using a special reader instrument .

Thanks for the prompt replies...chap had two goes at it ,first time car kept stalling on braking ,now drives ok but as i said engine management light on ...also seems to lack power at top end...anyone know what the setting should be ?

The timing needs to be set dynamically with the engine running at 1200 RPM.
To do this, depending which engine management system is fitted, you need either a Volvo scan tool, Vol-FCR, VADIS & VCT2000 or Vida & DiCE.

This post for the 850 should give you some info:

Don't worry. Despite the huge amount of information available on this job, garages continue to get it wrong in a big way. It isn't the "usual" sort of cambelt change in several respects, as the VW 2.5TDI unit has a few peculiarities from the 1980's when it was designed.

The biggest problem is convincing garages to spend the essential few quid to replace the diamond washer between the crank TV-damper pulley and the nose of the crankshaft. It's part of the job, it's in some kits (but not others) and it's essential - if you want your engine to continue turning for the next couple of years!
