The 2009 Golf is a compact 5-door hatch from VW's Mk6-era line-up; petrol automatics from this period were offered with either a conventional torque‑converter auto or VW's DSG twin‑clutch box. DSGs need their own regular oil/filter service and can be expensive to repair if the mechatronic unit or clutch packs develop faults; a conventional automatic will be simpler but slightly less efficient. Parts and independent garages are easy to find in Ireland, but expect older electrics, suspension bushes and corrosion to show on a 17‑year‑old car.

• Confirm gearbox type (DSG or conventional auto) and test for smooth, consistent shifts when warm; ask for evidence of DSG oil/mechatronic service if fitted.
• Timing belt or timing chain replacement date specific to the engine — verify replacement interval has been met (many petrol engines need a scheduled timing belt change).
• Rust inspection: check rear wheelarches, lower sills, boot floor and underside for corrosion or repair work.
• Suspension and steering: check for worn top mounts, creaks, sagging springs and play in the steering rack during a test drive.
