1998 Mercedes-Benz ML320 Problems

Replace air filter when replacing failed mass air flow sensor

The mass air flow (MAF) sensor tends to fail. The engine air filter should be replaced when the mass air flow sensor is replaced; a dirty filter can allow debris to damage the new sensor.

"No Start" Due to Drive Authorization's Failure to Recongnize Keys

A no start condition may develop due to an anti-theft system fault. If the drive authorization module fails to recognize the keys, the engine will not start. In many cases, a new module and keys will be needed to correct this problem.

AC System Leaks/Bad Temperature Sensors May Cause Poor Cooling

AC system leaks and/or a faulty evaporator temperature sensor can cause poor AC cooling. The failed sensor can prevent the AC compressor from coming on. Leaks cause a low refrigerant level, which reduces the ability to cool.

1998 Mercedes-Benz ML320 Reviews

Other than dash not showing temp of engine does the coolant sensor have any other function when not working properly. After belt snaped wires going to sensor broke. I replaced belt now I have no engine temp reading electric fans are on ALL the time and a/c stopped working
i HAVE NO POWER STEERING AND IS VERY HARD TO DRIVE, HOW DO i FIX AND WHATR WOULD THE COST BE $$
Loved it until everything went wrong at once. A/C, heat, seat heater-drivers, moon roof baffles, radiator and brakes all died within 6 months of one another.
