Mercedes-Benz 300TE Problems

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.

Cracked Driveshaft Flex Discs May Cause Driveshaft Movement/Vibration

A vibration felt through the center floor of the vehicle can be caused by cracked and/or shredded driveshaft flex discs, resulting in excessive driveshaft movement. If not repaired, damage to the driveshaft center support bearing, transmission, or differential can occur.

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

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

Mercedes-Benz 300TE Reviews

Awesome car! These cars were so over-engineered and built as to almost never wear out. We drive "Betty" all over the Big Island with no worries about break-downs, etc. If you think getting your oil/filter changed is a service, you're heading for trouble, no matter what you drive. I service the car well, near-new tires, belts, hoses, etc. replaced on a regular basis. Use only Premium fuel...
Over all the car is very well made mine has 270,000 miles normal maint is required.
love the car but always seem to need something. Best family car EVER
