•Connect VCDS or an OBD tool and check for EGR, boost, and coolant temperature fault codes before purchase
•Confirm coolant temperature reaches and holds 90°C on a 20 minute test drive, persistent low temperature is a red flag
•Inspect the EGR cooler and surrounding hoses for coolant staining or white residue indicating past leaks
•Check full service history for oil change intervals, reject any car with gaps over 15,000 km between services
•Verify which turbo variant is fitted (Borgwarner or Garrett) and check for shaft play and oil leaks at the turbo
•Request a compression and fuel pressure retention test on any example over 150,000 km before committing to purchase
•Confirm whether the Dieselgate emissions software update has been applied and note any change in reported fuel economy since
