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



MAF Sensor Replacement Time: 1 hour Tools: Flathead screwdriver Applicable Models: Mercedes-Benz C350 (2008-15) Mercedes-Benz GLK350 (2010-15) Parts Required: New MAF Hot Tip: Do not use oiled filters Performance Gain: Better mileage Complementary Modification: Replace air filters The mass air flow sensor (MAF) is used to measure the amount and temperature of air that is entering the engine at any one time. The mass air flow sensor senses the total amount of air passing the sensor and allows the fuel injection system to adjust the fuel mixture to compensate for cold weather and/or high altitude conditions. The MAF also incorporates an internal intake air temperature sensor that measures the temperature of the intake air. The first indicator that you might have a problem with the MAF is the presence of a check engine light (CEL) on your dashboard. The check engine lamp can be caused by a wide variety of problems with the engine: you need to read the codes from the computer to get a starting clue as to what the problem is. However, the engine will not be operating at peak efficiency, and you will most likely experience a loss in power and a decrease in gas mileage as a result. It's best to get the problem taken care of relatively quickly, as running the engine in this condition can potentially cause damage to other components like the catalytic converters. Vacuum leaks and other air leaks in the system can cause MAF sensor errors. If you have a crack or leak in your air intake downstream of the sensor, then the MAF will be sensing less air than the engine is actually receiving. You should carefully inspect all of your hoses, clamps and intake tubes for air leaks prior to replacing the sensor. You will need to remove the engine covers and air intake ducts to perform this work. Please see our article on engine cover removal. The new MAF comes complete in the air body housing so you will have to remove the complete housing to replace it. Changing the C350 MAF sensor is easy with our handy replacement guide. 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)

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...
