    I have a 2011 MS3 with 91,500 miles. Since I’ve owned it I’ve done regular oil changes and so on, all the maintenance I should do. This ticking noise outside of the fuel injectors is driving me crazy, it doesn’t go away when I press the clutch and the only issue I can see is that the idler pulley has some travel side to side when it’s spinning. I was able to move it enough to tap it by hand as well. This video was taken after about a 10 minute drive, no AC. AC on or off still makes the noise, all I can think is the idler because it definitely doesn’t sound like the timing chain to me. Anyone mind listening and helping me out? I made a short video where it’s audible.

    Take the belt off and spin stuff by hand. When I had this noise it was the A/C compressor clutch. I thought it was power steering at first but it was the bearings in the A/C clutch.

    That’s been part of the problem unfortunately, I live in a place where I don’t have a flat area to get it up on ramps so I haven’t been able to remove the belt. But I’ll see what I can do about that. The reason I suspect the idler is that it moves a bit more than the video shows side to side and makes a clicking noise if I move it to the side by hand. It’s confusing. Does it make a difference that it happens with AC off as well?

    I had a similar sound but got it louder with RPM but not all the time. Turned out my alternator pulley bearings were going out. I saw flex when I revved it at that pulley. While in there I replaced the idler pulley and belt after replacing the alternator.

    It’s something I’ve listened for but I definitely can’t hear it increase with rpms. The only one I see moving at all is the idler. I’m about to go take another look and do what I can with my limited work space. I appreciate all of you for the help.

    I should mention I found grease on the bearing of the idler pulley, another reason I suspect it

    It's all good just take some time and work through the diagnoses. If you need a new idler pulley there is a better one from autozone that moves the tensioner nut to a MUCH better place so you can get the belt on and off much easier. https://www.autozone.com/external-engine/belt-tensioner/duralast-idler-pulley-305372/78070

    Will do! I appreciate the help. I'll report back probably later today but I'm pretty certain it should be good after this. At least, I hope.

    I’ve replaced the idler and it sounds better, all the other pulleys sounded good. I still hear a faint ticking off time with the fuel pump but at this point it’s probably just a rock or some shit. I hear it near the IM but can’t pinpoint anything. So I’ll leave it alone.
