DSG gearbox service neglect
VW's direct-shift gearbox (DSG) — the 7-speed dry-clutch DQ200 on smaller engines and the 6-speed wet-clutch DQ250 on larger ones — requires a fluid and filter change every 40,000 miles or four years. Many private sellers overlook this. A neglected DSG can shudder at low speeds and eventually fail. Ask for DSG service stamps and cross-check the mileage history from a Carhealth report.
