Reduced Power Warning
Hey All,
I have recently come to own a 2008 Clubman S with ~117k miles on it. I had a couple of issues (leaky valve cover) that I have fixed and managed to clear and keep clear the CEL.
However, I still have a reduced power light (half filled engine icon) and seemingly no boost. (the care drives _ok_ but about what you would expect with no turbo) I pulled the supply hose on the turbo and everything in there seems to spin freely / not wobble.
I am not receiving any fault codes on my generic OBDII device. (although I have no access to a mini specific one)
Is it possible that a sensor (perhaps o2) is showing something as off and the car is killing the boost? Or is it more likely there isn't any vacuum (because of some leak I can't find) and so no boost?
Does anyone else have any ideas? I don't mind sinking a little money into it to try to get it going right, but at this point I feel like I would be throwing darts at a dartboard to guess, since I don't have any trouble codes to give me a clue as to where to start.
Thanks!
Chris

I encountered a similar situation. I took it to the dealer, since I have an extended warranty. They diagnosed as a faulty vanos solenoid. I believe this cuts your power because the lack of a functioning vanos solenoid keeps the engine timing from adjusting to higher RPM's...although I could be wrong on this point.

That said, does anyone have any suggestions on which ones work best? Or maybe which ones work well enough, but don't cost as much as the best?
