Engine judders and knoks at about 1500rpm

2007 Vauxhall Astra 1.3 dti Diesel
Car: Vauxhall Astra
Year: 2007
Variant: 1.3 dti Diesel
Categories: Running Rough, Starting & Power Loss
My Astra diesel car is done about 17,000 miles and has been regularly serviced. Recently at about 1500 rpm it judders and knocks and feels like it is losing power but at above 1500 rpm everything seems to be OK. It starts OK and runs fine at Ideal too.
Your help and comments would be appreciated.
