This is the standard 5-seat Volkswagen Tiguan with a diesel engine and automatic gearbox — if you specifically need seven seats you should look for the Tiguan Allspace (long-wheelbase) instead. Diesel Tiguans use a DPF and an AdBlue system and commonly have a DSG dual-clutch automatic; both need the right usage and service pattern (regular longer runs to allow DPF regen, and recorded DSG service/gearbox oil changes). Check for any outstanding software updates or recall work on diesel emissions components and note VW dealer warranty coverage on a 3‑year car.

• DPF condition: signs of frequent short-run regeneration (soot smell, frequent warning lights) and black smoky exhaust under load.
• AdBlue system: level sensor, refill history and any warning messages; check injector/pump operation if a fault lamp appears.
• Automatic gearbox (DSG): smooth up/down shifts, no judder or hesitation, and proof of gearbox oil/filter service at the recommended interval.
• Turbo and intake: listen for unusual whistle, check for oil leaks at turbo/intercooler hoses and clear throttle response under acceleration.
• Rear seats/ISOFIX and boot floor: check for uneven wear, water ingress or heavy loading marks that indicate family or towing use.
