The Mercedes CLS uses a 2.0 M264 petrol EQ Boost (258 bhp CLS300) and is classified as a coupe. Based on our workshop experience with Mercedes CLS in Hyderabad: M264 timing chain tensioner fault at 60,000 km. We also see white smoke from exhaust in vehicles that share similar engine architecture to the Mercedes CLS.
Never continue driving with an overheating engine — one episode of severe overheating can cause the head gasket failure that leads to white smoke.
Is white smoke always a head gasket?
Persistent white smoke from a warm engine is almost always head gasket until proven otherwise. The combustion gas test confirms it in 5 minutes. Cold-start white puff that clears quickly is normal condensation. GarageNation does the combustion gas test as part of the ₹1,500 diagnostic scan — never pays to guess on head gasket.
