The Mercedes-Benz A-Class Second (W169) Generation, 2004-2012, was praised for its improved handling, traction control, and more. This generation was not only available as a 5-door hatchback like the First Generation, but was also sold as a popular 3-door. This German compact car was praised for its dynamic safety features, increased storage space, selective damping system, and more; nevertheless, like any new auto, the make and model developed a few common setbacks, such as injector/valve problems.
This issue seems to be most prevalent in the W169 diesel engines. Strange noises, such as rattling, might indicate an impending issue. Whitish smoke, power loss, poor gas mileage, rough idling, misfiring, and unusual burning smells are other indications of possible injector failure. In the event of such a malfunction, you may experience all or none of these signs and symptoms.
Causes of such problems can include clogged or damaged fuel injectors. They can develop external cracks, especially if they are near the intake manifold. Addressing these issues right away is the best way to prevent further, potentially costly damage; if ignored, the result could be significant harm to other parts of your German import. Relevant diagnostic tests, such as fuel balance injector testing, lies far beyond the comfort zone and abilities of most drivers. If your luxury hatchback is demonstrating any of these common signs, please seek immediate and expert attention.
