Why Mercedes CLS Is Prone to Engine Oil Leak

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. Mercedes CLS models are among the brands we see most frequently for engine oil leak repairs.

Top Causes of Engine Oil Leak in Mercedes CLS

• Valve cover / cam cover gasket failure — most common oil leak on all cars after 80,000 km
• Crankshaft rear seal wear causing oil to drip from bellhousing area
• Oil filter housing O-ring or adapter seal failure
• Engine oil cooler hose or fitting seal failure
• Sump gasket or sump drain plug washer failure

How We Diagnose Engine Oil Leak on Mercedes CLS

• UV dye oil leak test — fluorescent dye added to oil, leak source glows under UV light
• Clean engine degreasing then short drive — fresh oil traces show exact leak point
• Smoke test for crankcase pressure faults causing blown seals
• Leak-down test if internal combustion leakage suspected

Prevention

Use correct oil viscosity and change oil at required intervals — degraded oil increases crankcase pressure and accelerates seal failure.
