Buyer's inspection checklist

🔧Engine & Drivetrain

Diesel cold start & idle stability — OM654 can rattle at startup in cold weather; should settle within 3 seconds.

DCT shift quality & hesitation — Test smooth acceleration from standstill; any judder suggests clutch wear.

🚗Body & Exterior

Paint depth & panel alignment — CLA bodies are aluminium-heavy; check for corrosion or poor respray.

Glass roof operation (if fitted) — Panoramic roof motors fail; test full open/close cycle.

💡Interior & Electronics

MBUX touchscreen responsiveness & mapping — Verify all menus load, GPS works, and no frozen screens.

Ambient lighting & power seat adjustment — LED strips fail; seat motors wear out—test all positions.

📋Service History

Full dealer service history & warranty status — Mercedes servicing is expensive; confirm all items documented.

DPF & oil fluid change records — Critical for diesel longevity; verify intervals (15k km) observed.

Recommended maintenance schedule

highEngine oil & filter service — Engine wear & sludge

Every 15,000 km
R1,800–R2,400

highDiesel DPF regeneration & monitoring — DPF blockage & limp-mode
