Groundwork
Mercedes-Benz is one of the most well-known motorcar manufacturers in the globe and continues to rival other automotive giants with their immovability and German engineering. Unfortunately, all cars have their shortcomings and failure points. For Mercedes, the camshaft adjuster solenoid (sometimes called the "oil control valve") is one part that prematurely fails.

What is a Camshaft Adjuster Solenoid/Oil Control Valve?
As office of the variable valve timing (VVT) system, the camshaft adjuster solenoid is responsible for allowing the oil to adequately period through the VVT system. The VVT system engages in delivering extra power to the vehicle when it's traveling under added stress, such as when it is carrying a heavier load, or when going uphill. Since the solenoid is necessary to permit the oil to lubricate the timing chain and gears if oil cannot accomplish these parts, then too much friction can cause them to vesture out quickly, this can lead to engine failure and expensive repairs.

Virtually Common Occurrences
Not all Mercedes vehicles feel a problem with the camshaft adjuster solenoid failing prematurely; nonetheless, the most frequently documented occurrences have place in the Mercedes-Benz E350 from the years 2006-2012, but has also been found in models like the C230. Failure usually occurs well before the 100,000 mile marker, oft in as petty as 50,000 miles, which is generally too before long for this part to require replacement. Mercedes has addressed the issue, giving specific replacement and repair instructions for the various faults when encountering this problem.

Common Symptoms Associated with Failure
It'southward essential to continue an eye out for the various symptoms your Mercedes may showroom when information technology encounters camshaft adjuster solenoid failure. At the beginning sign of problems, it'due south disquisitional to bring your car to a Mercedes specialist to accurately diagnose the event and get the trouble fixed correct away.

Check-Engine Light
Whenever your car'due south check-engine light illuminates, you shouldn't overlook it. The bank check-engine low-cal emits a code that your reliable Mercedes specialist will read with special equipment. Since Mercedes has addressed the solenoid failure result, your automotive specialist will likely follow the instructions for repair designated by the manufacturer.

Lowered Fuel Efficiency
Solenoid failure can likewise lead to diminished fuel efficiency. When the variable valve timing arrangement cannot function properly, and valves open up and close at improper times. This leads to engine performance and fuel consumption becoming significantly inefficient.

Contaminated Engine Oil
While the faulty solenoid won't probable cause engine oil to become contaminated, the reverse may be right. If y'all haven't kept up on your Mercedes' routine oil care and filter changes, the dirt and debris buildup can continue the oil from properly flowing through your engine. This can lead to damage of the VVT system, which tin can cause the solenoid to fail. If your engine oil is dingy, this could be the original cause of the trouble. This is why we recommend engine oil changes every 5,000 to 7,500 miles, rather than the standard 15,000-mile mark.

Rough Idling
If the solenoid is non letting the appropriate amount of oil into the system, then too much or as well petty oil could cause the engine to idle roughly. This can cause clogs if at that place is also much oil, and too little oil tin cause premature wearable to the various components within the engine.
