Rain and Light Sensor Replacement - C Class - W204 - Mercedes-Benz


Rain and Light Sensor Replacement Time: 30 minutes Tab: $60 Talent: 1 Tools: Small flathead screwdriver, trim removal tool Applicable Models: Mercedes-Benz C250 (2012-14) Mercedes-Benz C300 (2008-14) Mercedes-Benz C350 (2008-14) Mercedes-Benz GLK350 (2010-14) Parts Required: Sensor Hot Tip: Be careful working around the windshield Performance Gain: Working rain and low light sensor Complementary Modification: New wiper blades If your Mercedes has the rain/light sensor for the windshield wipers and it starts acting up, changing out the sensor is quick and easy. The sensor is attached to the front windshield and can be replaced without removing the windshield. The sensor determines rain by sending an infrared light from the transmitter in the sensor up into the windshield. If the windshield is clear almost all of the light will be reflected back to the sensor. If there is rain on the windshield then some of the light will be refracted and spread by the rain drops and cause a low light signal back to the sensor. The more rain the more light that gets dispersed. The low light is measured directly by the amount of light intensity falling on the sensor. Start by shutting off the car and removing the key from the ignition. Replace your rain light sensor with these step by step instructions Applies to: C350 (2007-14), SLK350 (2004-14), CLS350 (2004-14), CLK350 (2005-14), E350 (2005-14), S350 (2005-14), SL350 (2005-14), R350 (2006-14), ML350 (2006-14), Viano (2005-14), Sprinter (2006-14), CLC350 (2008-14), GLK350 (2008-12), 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...
