Hi Steve, just to clarify a little more, the TD5 engine has two oil filters, a conventional one and a centrifugal one, which the last guy was referring to. If you look under the bonnet, it's on the right side of the engine, a few inches below the top and in the middle, roughly, and a little hidden. It's about 4" in diameter. It has 3 x 10mm bolts holding the top on. Inside there's a very small dome shaped filter which whizzes round at great speed and being well lubricated, it carries on after the engine stops. When you get around to your own servicing in 3 years, it'll be a job to do. The top is sealed with a large 'O' ring.
