Hi all,
Can someone please post the instructions on how to do the cleaning of both valves/sensors? I am having rough/low idle issues lately. I just replaced the DISA Valve, which was broken(Pin was still on it/did NOT go into engine

). I'm wondering if my MAF is bad or dirty. I have 158K miles on my '04 X5 3.0i. Thanks for any help/advice!
