Most common cause of loss of vacuum on the diesels is leaking EGR pipework. As a double check try removing the pipe and blanking it off at the connector.
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.
