Hi, sorry I am sure I am dragging up an old thread but I an new to this n54. It is a 2008 535xi with about 66k miles on it. If I drive the car normally it runs fine, idles fine all that, if I rev it in the driveway it will do it great. But if I get on it harder than normal driving it seems to fall on its face and the engine malfunction, reduce power light comes on. I don't seem to lose a lot of power but some, I also noticed more than normal condensation from the exhaust and a very small oil leak. My only thought is the pcv, any thoughts? Thanks in advance.
Hello and welcome to the forum! If you're getting a CEL, get the codes read. It'll be a great place to start troubleshooting.
