Buying Used Proton S70 Malaysia — Checklist
Used S70 checklist: DCT shudder test. Software update applied (Proton SC history). Carbon: rough cold idle at 60,000+ km. Oil change history (0W-20 fully synthetic). EPB function. Battery condition. 3-cyl idle: baseline vibration is normal.
- OBD + dealer scan: DCT codes, adaptation values, engine faults
- Cold start: 3-cyl vibration normal — but any DCT shudder at 10–30 km/h?
- Software version: is DCT firmware updated to latest Proton release?
- DCT fluid history: changed at 40,000 km? Newer S70 may not have reached this yet
