Best Garage In Bellevue To Tackle Your BMW’s Crankcase Ventilation Valve Malfunction

BMW, historically, has certainly been one of the world’s best-built, engineered cars. Yet regardless of how things are made, all machines tend to have failing components after a few years, and depending on what type of preventive maintenance is taken. A BMW crankcase ventilation valve malfunction is one issue you may see during the life of your BMW. Let’s take a look at how to know you are having this issue and what to do if you suspect it happening with your car.

Function of a Crankcase Ventilation Valve

Known as a CCV or PVC valve, the crankcase ventilation valve is a key part of your car’s crankcase ventilation system. As your car operates with you behind the wheel, engine blow-by gases accumulate within the crankcase. The crankcase valve takes these fumes and releases them into another system of your BMW that does not allow the fumes to exit into the environment.

Symptoms of a Failing Crankcase Ventilation Valve

Driving with a failing crankcase ventilation valve will normally allow you to make it to a mechanic shop if it begins to fail. Take heed, however, as continuing to operate your BMW or any other car with a crankcase ventilation valve issue can result in a buildup of carbon. This can cause serious issues for your engine.

The best thing to do if you suspect that your crankcase ventilation valve is failing is to take your BMW to expert technicians trained in how to service your brand. Now, let’s take a look at a few signs you may be losing your crankcase ventilation valve.

• Rough Idling: If your BMW is experiencing an issue with your crankcase ventilation valve, you will notice a rough idle. Since your car’s computer must adjust to any vacuum leaks, as happens with a failing crankcase valve, it will constantly try and compensate. This compensation will be the cause of a rough idle.
• Check Engine Light: The illumination of the check engine light is almost certainly to trigger when the crankcase ventilation valve is failing. Although you will not know right away what is wrong, having your car’s check engine light troubleshooted by a BMW technician will certainly show the true cause.
• Misfires: A misfire is another sign that you are having issues with your crankcase ventilation valve. This will normally be combined with rough acceleration and possible jerking sensations when trying to speed up. These misfires will normally be captured and cause the check engine light to illuminate.
• White Smoke: A noticeable white colored smoke exiting out of your BMW’s tailpipe is another almost sure giveaway that you are having issues with your crankcase ventilation valve.

Preventing Crankcase Ventilation Valve Failure

There is no reason a crankcase ventilation valve should fail when it is new, unless there is some type of contamination that has made its way in. Although there can be some extreme environments where this could take place, or by bypassing an air filter, chiefly inadvertent damage to the valve by an unskilled technician or owner can also be a cause.

By having your BMW serviced within the recommended manufacturer’s guidelines by expert technicians who are trained on how to take care of your BMW, you may go the life of your vehicle without ever experiencing an issue. The crankcase ventilation valve is recommended to be changed around 50,000 miles. If these recommended replacements are ignored, you are almost certainly going to experience this issue with your BMW.
