Can anyboby tell me what a charge pressue sensor does and would a faulty one make my 2000 Astra 1.7dti sluggish

It senses the turbocharger boost pressure that is present in the inlet manifold.
Yes, if faulty, it would have a detrimental effect upon engine power output.

Thanks for that DL can you tell me if it is possible for the DIY man to check that the charge pressure is faulty or not

Apart from checking the connections to the unit are sound there isn't a whole lot you can do to test the unit I'm afraid. The ECU has a self diagnosis function which will flag up any faults and are readable by a suitable code reader or scan tool (£££'s)
Reading and observing live engine data is also possible - the boost pressure sensor (using it's more generic name) is one of these.
Have you noticed a loss in performance, I take it?
