EGR Change Over Valve Replacement - C Class - W204 - Mercedes-Benz


EGR Change Over Valve Replacement Time: 1 hour Tab: $40 to $100 Talent: 1 Tools: Hands Applicable Models: Mercedes-Benz C350 (2008-14) Mercedes-Benz GLK350 (2010-14) Parts Required: EGR change over valve(s) Hot Tip: Order some vacuum hose before you start Performance Gain: Pass a SMOG test Complementary Modification: Change the oil filter If you are having trouble passing a SMOG test and getting an error code that the EGR change over valves are faulty you can replace them yourself, though you are going to have a fair amount of work ahead of you. The valves are located at the front bottom of the intake manifold and cannot be accessed without removing the intake from the engine. Please see our article on intake manifold removal for step-by-step instructions. If you are replacing the valves it is a good idea to order some replacement vacuum hose along with the valves. The rubber vacuum hose that attaches the valves to the hard lines gets very brittle. You do not want to hang up the job over a couple of inches of vacuum line. The valves are the same and interchangeable. Changing these valves means removing the intake manifold but don't worry we will take you through it step by step 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...

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...
