So my camshaft position sensors (both intake and exhaust) are bad and need replacing. I've never performed any of my own repair work on my car (2001 330i MT), but I'm looking to start. The Bentley manual makes me think replacing the sensors isn't too terribly difficult. I'm hoping there are a couple people on here that can give me an idea how hard this project is and how long it might take a novice. Also, does anyonoe have any advice or tips were I to attempt it myself? Thanks for the help.
