dereklau007 1 Report post Posted October 27, 2013 Hi Everyone, Halfway through my CCV, OFHG (including vanos oil line and crush washers) and 2 camshaft position sensor marathon I noticed that my ICV was a little dirty and wasn't moving around freely. I cleaned it with some carb cleaner and it was a little better however now after some twisting (like you would on a bike throttle) there is a rattling sound that I've never heard before. Did something break inside the ICV? Didn't want to reinstall everything and find the ICV is busted... Any help would be greatly appreciated. Car info: 2002 530i (M54 engine) Cheers, Derek Quote Share this post Link to post Share on other sites
Arma 134 Report post Posted October 27, 2013 (edited) Is this with the engine running? If yes, are you 100% the rattling is coming from the ICV? And not from the disa valve or anything? Edited October 28, 2013 by Arma Quote Share this post Link to post Share on other sites
dereklau007 1 Report post Posted October 28, 2013 Are you 100% the rattling is coming from the ICV? And not from the disa valve or anything? 100% sure because it's the ICV that's in my hand with the odd sound. As I originally posted "I cleaned it (ICV) with some carb cleaner and it was a little better however now after some twisting (like you would on a bike throttle) there is a rattling sound that I've never heard before" To clarify the noise it's more like a loose ball bearing in a can type of sound.
