1999 Mercedes-Benz CL500 Problems

Leaks Develop at Differential Seals/Cover on High Mileage/Older Vehicles

Leaks may develop from the differential cover and/or seals on high mileage or older vehicles. Our technicians recommend a complete reseal of the differential unit if these leaks are addressed.

Coolant Leak Due to Cracked/Broken Heater Core Outlet Housing

A cracked or broken heater core outlet housing can cause a coolant leak near the bulkhead (firewall). Our technicians remind us that coolant leaks should be repaired in order to avoid overheating the engine due to coolant loss.

Faulty Mass Air Flow Sensor Causing Erratic Engine Operation and Poor Fuel Economy

A faulty mass air flow (MAF) sensor can cause erratic/rough engine operation and fuel economy issues. Since this sensor measures the actual amount of air entering the motor, when it fails, the engine control module (ECM) takes the wrong information and delivers incorrect volumes of fuel to the cylinders.
