🚨 What to check before buying

Overall risk score: 8/10

Serious risks

Carbon buildup (DI): Direct injection causes carbon deposits on intake valves — walnut blasting needed.
PCV/oil separator: PCV oil separator can fail, causing oil leaks and idle issues.
Timing chain tensioner noise: Occasional chain tensioner noise on cold start at higher mileage.
Car is 14 years old — expect age-related wear: rubber seals, bushings, water pump, AC compressor
Higher mileage (168,338 km) — check for timing system condition, turbo health, and suspension wear

Additional notes

Mercedes M278 4.7 V8 twin-turbo with 100k+ km: timing chain tensioners and guides wear, causing rattling on startup. Chain is at the front but still expensive due to engine complexity. Also prone to: turbo actuator failure, air suspension issues (in S/CLS-Class), and expensive sensor failures. Budget €2,000-4,000 for timing chain service.
