I've been thinking about this since you posted and am coming up blank. You may have better luck at clubsmartcar.com as the diesels were officially sold in Canada, so there will be people more acquainted with it.

Most of the diesels cars have that oil look to them. One of the main things that go bad on the diesel cars is the clutch arm going bad it can cause all kinds of problems. Also look at the axle ends and see if the ABS rings are broken and that will cause the triangle light to come on.
