What to Look For

• Rod bearing wear — common on S-series engines
• VANOS system failures cause rough idle and power loss
• Subframe cracking on E46/E36 models
• SMG pump and actuator failures if equipped
• Same S85 V10 as E60 M5 — all the same issues
• SMG-III even more costly to repair
• Heavy car — brakes wear faster

Pre-Purchase Checklist

• Rod bearing clearance check or oil analysis for metal content
• VANOS rattle test — listen at idle and on-off throttle
• Inspect subframe mounts for cracking (E46 especially)
• Check SMG pump accumulator pressure if equipped
• Verify service history at BMW specialist
