Top Issues 2010-16 Mercedes-Benz E-Class (W212)

How to Fix Transmission Shifting Problems

Replace the turbine speed sensor. Consider bringing the vehicle to a professional as this is a comprehensive job and involves disassembling the transmission

2. Bad Crankshaft Position Sensor

The crankshaft position sensor may not be the cause for these symptoms, but if it is we recommend replacing the camshaft position sensor at the same time. Both of these parts can go bad, cause similar symptoms, and are located in similar areas.

Symptoms of a Bad Crankshaft Position Sensor on the 4th Gen Mercedes-Benz E-Class

  • Car dies when driving down the road
  • Engine cranks but fails to turn over when starting
  • Car starts, sputters, and eventually dies out
  • Symptoms are usually accompanied by a check engine light and P0336 code

How to Fix a Bad Crankshaft Position Sensor

Read the code from the check engine light with a scan tool and if replacing the crankshaft position sensor, replace the camshaft position sensor also

3. Worn Thrust Link

Symptoms of a Worn Thrust Link

  • Uneven wear on the tires
  • Tire wear on the inside/inner edge

Causes of a Worn Thrust Link

The forward thrust link helps keep the wheel from thrusting forward or backward. Sometimes the bushing on the end of the link rots, cracks, or loosens and separates, causing the forward thrust link to move easier. This play is rarely felt by moving the tire like when testing for a bad wheel bearing or bad ball joint, but it will cause uneven tire wear.

How to Fix a Worn Thrust Link

You can remove the forward thrust link and replace the bushing, but if this job feels too advanced, you can replace the entire forward thrust link

After completing this repair, we recommend a wheel alignment

4. Interior Part Issues

While the E-Class has a luxurious interior, there are some common issues with some of its interior parts, such as creaking or rattling trim panels when driving over a bump or seats that need to be repaired from tearing at the seams.

Symptoms of Interior Part Problems on the 10-16 Mercedes-Benz E-Class (W212)

  • Faded wood paneling
  • Creaky interior panels and trim
  • Navigation knob works intermittently
  • Ripped or torn seat cushioning

How to Fix Interior Part Problems Issues

  • Polish faded wood paneling
  • Apply shim to the interior panels and trim
  • Rebuild or replace the navigation knob
  • Repair the seat by reupholstering or replacing it

5. Automatic Digital Temperature Control Valve

Symptoms of a Bad Automatic Digital Temperature Control Valve

Auto button does not set the cabin to the desired warm temperature and cold air blows through the heat vents instead

Causes of a Bad Automatic Digital Temperature Control Valve

The auto button controls the automatic digital temperature control valve, which is located underneath the windshield wipers, cowl panel, and windshield wiper motor and linkages. It is placed on the firewall with a valve that has coolant hoses and an electrical wire leading to it.

The valve wears out because it has a two-piece housing unit sealed with a gasket. Once the gasket is defective, moisture gets inside, which leads to rust and corrosion on parts like the motor, bearings, gears, and shafts.

How to Fix a Bad Automatic Digital Temperature Control Valve

Locate the unit and test for power and ground. If there is power and ground, follow the standard procedure for removing it since it involves coolant.

Remove and take apart the two housings. If rust or corrosion is inside and wearing internal parts, chances are it needs to be replaced.
