Common Engine Problems
Valvetronic Intermediate Levers
BMW 6 Series engines are known to have issues with their Valvetronic intermediate levers. These levers are responsible for helping control the airflow and valve lift within the engine.
Over time, they can wear down, which affects the engine’s performance and fuel efficiency. Symptoms include a lack of power, poor acceleration, and increased fuel consumption.
To fix this issue, you may need to replace the intermediate levers.
Crankshaft Sensor Issues
Another common problem with BMW 6 Series engines is related to the crankshaft sensor.
This sensor monitors the position and rotational speed of your car’s crankshaft, which is essential for proper engine timing and ignition.
If the crankshaft sensor starts to fail, you may experience stalling, poor engine performance, and even a possible no-start condition. If you notice any of these symptoms, have the crankshaft sensor checked and replaced if necessary.
A rattling noise coming from your BMW 6 Series engine compartment is another issue that might be of concern.
This could be caused by various factors such as worn timing chain guides, loose accessories, or even a failing Vanos system, which is responsible for adjusting the engine’s camshaft timing.
To identify the exact cause of the noise, enlist the help of a trusted mechanic who can thoroughly inspect the engine and provide the necessary repairs. Remember that addressing engine noises promptly is vital to prevent further damage or costly repairs down the line.
Battery Life and Replacement
Your BMW 6 Series’ battery life may degrade over time. To maintain optimal performance, you should replace the battery when it starts showing signs of wear. Look out for dashboard warning lights, slow engine cranking, or dimming headlights.
Check Engine Light
If the check engine light turns on in your 6 Series, it signifies a potential electrical issue. It could result from various problems, such as a failing electrical component or a faulty sensor. Ensure you have the car diagnosed and resolved promptly to avoid further complications.
Suspension and Rust Concerns
Front Strut Spring Cups
In your BMW 6 Series, a common issue is the front strut spring cups. These components sit on top of the suspension dampers and may rot out over time, which can cause suspension problems.
Rust and Corrosion
Another concern with the 6 Series is rust and corrosion. You should regularly inspect your vehicle for any signs of rust, particularly in areas where suspension components connect.
Addressing these issues promptly can prevent further damage and maintain the integrity of your BMW 6 Series’ suspension system.
Recalls and VIN Checks
Throttle System Recall
If your BMW 6 Series experiences problems with the throttle system, be aware of a past recall. Check your vehicle’s identification number (VIN) on the official BMW Safety Recalls website. This recall was issued due to faulty sensors, requiring a new sensor installation.
Counterbalance Shaft Recall
Another issue for 6 Series owners could be related to the counterbalance shaft. In this case, also utilize the VIN search tool to identify if your BMW is affected. Promptly address the recall to ensure smooth functioning.
Tips for BMW 6 Series Owners
To prevent common problems, it’s essential to perform regular maintenance on your BMW 6 Series. Check your car’s fluids, such as engine oil, coolant, and brake fluid, and replace them when necessary.
Ensure your tires are properly inflated for optimal handling and fuel efficiency. Schedule periodic inspections of your car’s engines to avoid potential issues.
Caring for Your 6-Series
Taking good care of your 6-Series can extend its lifespan and reduce the need for repairs. Keep the exterior clean, using a high-quality car wash soap to avoid damaging the paint.
Regularly clean the interior, paying attention to upholstery and leather surfaces. Address common problems promptly to avoid further complications and enjoy your ride with confidence.
