Check its had a cam belt + aux belt.
Beyond regular servicing my 184tdi at a similar mileage has had:
rear dampers
front dampers + top mounts
front wishbones + drop links
front wheel bearings
discs and pads
heater matrix (check it blows hot air across all vents)
AC re-gas (check it blows cold air across all vents)
dog bone mount bush (engine lower torque reaction arm bush)
Uses about 0.12 liters of oil per 1000 miles - which is 1/4 of the maximum allowance - (seems fairly common)
Also i'm using a little coolant - so I suspect EGR cooler or Front mounted water/air heat exchanger.
