Buyer's inspection checklist

🔧Engine & Drivetrain

Turbo spool & EGR cleanliness — 1.9TD can suffer carbon buildup; listen for lag or rough idle.

4x4 transfer case engagement — Verify 4x4 locks smoothly; check for clunking when shifting between 2H/4H.

🚗Body & Exterior

Extended cab door seals & hinge play — Rear doors prone to sagging; check for water ingress and rattles.

Undercarriage rust & chassis integrity — Bakkie frames corrode in high-rain regions; inspect underside for pitting.

💡Interior & Electronics

Dashboard illumination & cluster accuracy — Older D-Max units sometimes suffer dim LCD or erratic gauge readings.

Air-con function & cabin odour — Diesel vehicles accumulate humidity; check for mildew in cabin.

📋Service History

Full service record & oil change intervals — Diesel engines demand regular oil changes to prevent sludge and turbo wear.

Filter & fluid status (oil, coolant, ATF) — Verify fluids are clear and at proper levels; dark oil = overdue service.
