Mercedes-Benz E-Class Carbon Cleaning Malaysia
Mercedes-Benz E-Class direct injection carbon buildup — walnut blasting at 60,000–80,000 km. Malaysia pricing.
Carbon buildup on intake valves is a concern for W212 M274 4-cylinder and all W213 E-Class models — both use direct injection (GDI). The W212 M272 V6 is port-injected and does not suffer from intake valve carbon deposits.
E-Class models in Malaysia are commonly used as executive commuters — short trips in KL, AC always on, frequent idle in traffic. This is the worst profile for GDI carbon accumulation. Walnut blasting every 50,000–70,000 km is recommended. Cost at 4M Car Care for the 4-cylinder M274.
