(Translated from German)
Summary of the thread
A 2008 BMW 5 Series owner is experiencing engine issues, including a check engine light, reduced power, rough running, increased fuel consumption, valve rattling, metal shavings in the oil, and strange engine noises. The suspected cause is a fault in the exhaust VANOS system. Suggestions include checking the oil pressure control valve, replacing VANOS solenoids, cleaning the system, and consulting a professional for a thorough diagnosis due to the potential for serious internal engine damage.

Hey, thanks for your reply. As for the performance, unfortunately I don't have exact figures as it's difficult to tell at the moment with the reduced power and weird engine behavior. I will take your suggestions into consideration though and take my car to the garage to have the oil pressure control valve checked. Hopefully it's that and nothing worse.

Hey, no problem, I'm happy to help. Yeah, it definitely sounds like a trip to the garage would be a wise decision, especially if you've noticed that there are metal shavings in the oil - that's not usually a good sign. I certainly hope it's nothing more serious and that the fault can be fixed quickly and cheaply. Keep your fingers crossed! Good luck to you!

Good day, it sounds like your VANOS system might be failing. I had similar issues with my BMW 5 series, and my mechanic replaced the VANOS solenoids and cleaned the system. Additionally, you can check for oil sludge and replace the oil filter. If you feel more comfortable then consult a professional for a thorough diagnosis. All the best!

It's definitely a good idea to have a professional look at your car, especially considering the metal shavings in the oil. This could indicate serious internal engine damage. The VANOS system could indeed be the culprit, but it's also possible that there are other issues at play. Please don't delay in getting your car checked out.

Hi, I had a similar problem with my 2006 BMW 3 Series. I have minimal experience with cars, but I hope I can still be helpful. In my case, the cause was a defect in the oil pressure control valve, which caused the engine oil pressure to be regulated incorrectly. I took my car to the garage and they solved the problem for me. In the end, I had to pay 280 euros for the repair. The symptoms you describe sound very similar to what I experienced - you could be right in your assumption. Best regards
