Mercedes-Benz CLA — 漏油问题
CLA Oil Leak Guide
CLA C117 M270 and C118 M260 share identical oil leak failure points with the A-Class. The oil separator hose is the first thing to inspect on any CLA with blue smoke or oil consumption above 0.5L per 5,000 km. Valve cover rear corner and turbo return line are the secondary suspects.
Repair Cost
- Oil separator hose
- Valve cover gasket
