Mercedes-Benz 600SEL Problems
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.
A coolant leak may develop form the Radiator due to degradation of its plastic components. Replacement of the failed radiator will be necessary.
Vehicles with automatic level control that ride harshly in the rear (no give in the suspension) may have one or both dampening actuators which have failed. It is commonly recommended the actuators be replaced in pairs.

Major problems include evaporator ( $3,000.00 +) and wiring harness issues ( $5,000.00+). Every 600 made before '95 will have to have the wiring harness replaced since Mercedes used a biodegradable coat...
