The paper filter inside was covered in a slimy gloopy sludge aswell.
I had a slight shudder throughout the car at low revs, most noticable at 70-80mph even on glass like roads, I was convinced there was a gearbox issue and was lining up a fluid change. The shudder is gone after the filter changes so i guess it was partailly blocked and starved of fuel at low revs.
A lesson to start simple!

Hey that's interesting. I have a very slight shudder between 50-60 mph. I've had the wheels balanced/checked and a 4 wheel alignment (checked, and it was fine) and replaced all four tyres, still there, very slightly, and bugs the s@*t out of me.
How easy was the diesel filter to replace?
