Any one know the part number for teh fuel filter.

Got one from euro car parts but it doesent look like the one ive got on the car!! :/

What engine??

There are 3 listed for the 170 (PD) engine. I had to buy all 3 when i changed mine and then took back the 2 i didn't need. They are all very different.

It's a 1.9 tdi on a 2008 plate.

The only certain way is to look what's already on the car, a variety were fitted and even main dealers can't tell without looking. The filter housing usually has a manufacturers name and/or VAG part number stamped on the outside which can be used to cross-reference the filter element needed.
