ABS Sensor Replacement - C Class - W204 - Mercedes-Benz



ABS Sensor Replacement - C Class - W204 - Mercedes-Benz



ABS Sensor Replacement Time: 2 hours Tab: $40 to $200 Talent: 2 Tools: 10mm wrench, E12 wrench, floor jacks, jack stands, wheelchocks, safety glasses, torque wrench Applicable Models: Mercedes-Benz C250 (2012-14) Mercedes-Benz C300 (2008-14) Mercedes-Benz C350 (2008-14) Parts Required: ABS wheel speed sensors Hot Tip: Check for fault codes before replacing Performance Gain: Repair faulty ABS sensor Complementary Modification: New brake pads The ABS wheel speed sensors on the W204 monitors road wheel movement and sends an electronic signal to the ABS module. This signal is used to calculate road wheel speed to help with ABS braking and stability control features. When an ABS wheel speed sensor fails, the ABS module loses road wheel speed for the corresponding wheel and sets a fault code for the ABS wheel speed signal. When a fault code is set, the ABS warning light will illuminate. You will have to scan the module and read the fault codes to determine which speed sensor is the problem. Keep in mind, other problems can illuminate the ABS warning light. Be sure to scan and read fault codes before you start replacing expensive parts. Begin by safely raising and supporting the vehicle and removing the wheels on the sensors you are changing. Please see our articles on these procedures for additional help. If you have an error code requiring you to change out an ABS wheel speed sensor this article will show you how Applies to: C350 (2007-14), C180 (2007-14), C200 (2007-14), C230 (2007-14), C250 (2007-14), C280 (2007-14), C300 (2007-14), C320 (2007-14)

Crankshaft Positioning Sensor Replacement - C Class - W204 - Mercedes-Benz Crankshaft Positioning Sensor Replacement Time: 2 hours Tab: $20 to $40 Talent: 1 Tools: T30 Torx Applicable Models: Mercedes-Benz C350 (2008-14) Mercedes-Benz GLK350 (2010-14) Parts Required: Crankshaft positioning sensor Hot Tip: Use a mirror Performance Gain: Smoother running car Complementary Modification: Replace Camshaft positioning sensors Your fuel injection computer (DME) may output a code that indicates a faulty camshaft position sensor (CPS). This important sensor tells the car's computer where the flywheel is located in relation to the combustion cycle. The DME takes the signals from both the cam position sensor and crankshaft position sensor, and calculates when to fire the fuel injectors and spark plugs. If the crankshaft position sensor is not operating properly, your car will run very erratically or perhaps not at all. Replacement of the sensor is not as easy as the camshaf...

Yaw Rate Sensor Replacement - C Class - W204 - Mercedes-Benz Yaw Rate Sensor Replacement Time: 2 hours Tab: $320 Talent: 2 Tools: Trim removal tool, E12 socket, T45 Torx driver, 10mm socket or wrench Applicable Models: Mercedes-Benz C250 (2012-14) Mercedes-Benz C300 (2008-14) Mercedes-Benz C350 (2008-14) Parts Required: Yaw rate sensor Hot Tip: The sensors are sensitive to shock; use care when working with them Performance Gain: Working ESP Complementary Modification: Clean carpet and interior beneath seats The yaw rate sensor is located below the driver side seat and is used to measure the yaw, lateral and longitudinal acceleration of the rotation around a vertical axis. This sensor is used to supply information to the Electronic Stability Program and has been known to fail in the past. If you are getting an error code for the yaw sensor and need to replace it this article will show you how. The sensors are sensitive to impact so use care when working with it and be ca...

Front Stabilizer Bar Replacement - C Class - W204 - Mercedes-Benz Front Stabilizer Bar Replacement Time: 2 hours Tab: $170 Talent:2 Tools: E12 Torx, T40 Torx, 18mm, 13mm wrench Applicable Models: Mercedes-Benz C250 (2012-14) Mercedes-Benz C300 (2008-14) Mercedes-Benz C350 (2008-14) Parts Required: New stabilizer bar and hardware Hot Tip: Don't let the bar fall on you Performance Gain: Better handling If you are starting to hear a knock sound when you go around a corner there is a good chance your sway or stabilizer bar bushings are starting to go bad. Unfortunately, the rubber bushings on the stabilizer on the W204 are vulcanized to the bar and cannot be replaced separately. This means you will need to drop the bar and replace it with a new one. All of the mounting hardware is considered single use so make sure you order new hardware when ordering the bar. You will need to jack up the car and remove the front wheels along with the under body trays to perform...
