depending on when last service was done, you will need to change the following-oil, oil filter, coolant, check/change the following-glow plugs, air filter,also check brake fluid level, abs fluid, pas fluid, brake pads & disks, cv boots. you might as well check if you have timing belt, and if so, when was it last changed? should be done roughly every 60000-70000 miles or 5 years, whichever comes first.
hope it helps, August 2010
