Mercedes-Benz S-Class Used Car Checklist Malaysia — W222/W223

Buying a used S-Class? This is one of the highest-risk used car purchases in Malaysia — the maintenance backlog on a neglected S-Class can be enormous. A full pre-purchase inspection including XENTRY scan and AIRMATIC assessment is essential.

• Park on level ground for 30 min, return: any corner visibly lower = air spring or valve block leak
• Start car: listen for compressor running time — more than 90 seconds on startup indicates leak
• XENTRY AIRMATIC scan: check fault codes, adapt values and compressor pressure readings

• Test 9G-Tronic: pullaway judder = ATF overdue
• Ask for transmission fluid history — any S-Class without ATF record should get immediate flush
• Cold start V8 chain check (first 5 seconds of startup)
• Carbon cleaning history: any S-Class over 60,000 km — budget RM 1,500–3,500 if none

• XENTRY full scan all 60+ ECUs — essential on any used S-Class purchase
• Battery age: S-Class dual battery — both may need replacement (budget RM 1,500–2,500 for both)
• Test all comfort features: massage seats, power rear sunblind, seat ventilation — repairs are very expensive
