Yes the vacuum pump can be removed and cleaned. If I remember correctly it is a simple vane pump so check for wear and that the vanes aren't sticking. Also make sure the end plate gasket isn't letting by.
Treating yourself to a vacuum gauge might help with the faultfinding - they aren't that expensive.

Thanks Mike. Ill test vacuum latter. Do you know its ideal reading on a gauge.? Ill strip and clean pump if its low. EGR pipe is ok but will check again. Vacuum is still there 24 hrs after engine off..
