Mercedes-Benz E320 BLUETEC ProblemsSRS Light Due to Water Damage on Passenger Seat Weight Sensor
Water can damage the weight sensor in the front, passenger seat, causing the SRS (airbag) light to illuminate. There is an electrical component in the seat cushion susceptible to fluid damage. Any spills should be dried up immediately in order to try and prevent damage to the sensor.
The brakes may begin to squeak at about the 50 percent wear point. This is due to the size and material used for the brake pads and rotors. The brake rotor surfaces become uneven, causing a lip to form at the outer edge. This will generally require replacement of the rotors when the pads are worn (pad life varies depending on driving style and terrain).
It is not uncommon to encounter premature failure of the anti-lock brake system (ABS) modulator assembly due to dirty brake fluid. Our technicians recommend flushing the brake fluid every two years in order to help prevent this problem.
Mercedes-Benz E320 BLUETEC QuestionsCar lost power. Technician believes it to be a turbo charger issue. (1 answer)
Upon entering freeway and stepping on gas, there was no power to gain speed. Took quite a long time to reach 60mph. Drove to Dealership. Initial diagnosis is turbo charge issue. What can I expect? A hose, maybe a gasket? What are labor costs involved for turbo charge related issues?
The gear shifts from N to D happens with a jerk and while driving the gear automatic gear shifting does not take place. The engine runs at high rpm. Then when I switch off and restart, the problem goes away.
This problem happens sometimes.
Restarting the engine seems to reset the sensor.
