Check out the clip....

M3 clutch squeek

Its coming from under the car on the tranny right where the clutch bleed nipple is. Any easy way to cure it?

TIA

Does the car make any ratting noises at idle or whining noises when you shift?

Sounds like either the throwout bearing is getting hung up on the input shaft bearing retainer, and/or the pivot fork is off alignment somehow.

Is it getting worse with time? That could spell disaster pretty soon.

doesnt sound "good" ...

I'm with Nick, and sounds like something INSIDE the bell housing

I have a similar issue, but the sound went away overnight. It happened after flogging the car on one of the first hot days of spring last week. My service writer at the dealer said to keep on eye on it. He says it sounded like either the throwout bearing or fork. He also said to try to grease the slave cylinder shaft where it makes contact with the fork with a graphite based lubricant. Please do tell what happens with your noise. Thanks.

Negative on these symptoms. No rattles, or whining noises. The tranny actually shifts quite well.

Flogging? I've never heard this term before. Could you elaborate? Lubing the slave shaft sounds like a good start. That requires clutch slave removal, and likely a complete bleed upon installation, correct?

Noisy slave cylinder, I think. I have the same noise, just not as pronounced.

Agreed from the sound, and easiest to replace.

OP - If it is the slave cylinder, do it sooner than later. A failed seal in the slave can add air to the lines which are shared with the brakes.

Fiveightandten's suggestion is valid too, requires more work.

Whoa...It sounds bad...

Flogging means driving spiritedly, I was going through my favorite twisty curves and winding out the gears, so the car was hot when I pulled into my driveway and noticed the squeaking clutch.

My service advisor said that you should be able to go under the car and pull away the rubber boot that covers the slave cylinder/clutch and lube the output shaft of it that engages the flat sheet metal fork that engages the clutch without removal of the slave cylinder.

Sorry I have not had a chance to test this solution yet. Hope this helps. I am dreading having to take my M in for a throwout bearing in the future.

There's a rubber boot that covers the slave cylinder and clutch? Last time I checked, my bell housing wasn't rubber.

The slave cylinder is held in by 2 nuts. It's quick and easy to remove. He can try putting a dab of grease on the end of the pushrod. To me this sounds like something much more than the pushrod though. But it's worth mentioning that the pushrod should have a rubber sleeve on the tip of it. It's possible the rubber wore through and it's scraping metal on metal. If this is the case, replace the slave cylinder.

Also note that you should be VERY careful of 2 things:
1) Do NOT actuate the clutch pedal with the slave off the transmission. You'll have a messy surprise.
2) Take great care when reinstalling the slave to be sure the pushrod is pressed into the divot in the pivot fork. If it's no aligned correctly, you'll be fishing the pushrod out of the bell housing when you press the clutch down and it shoots into the transmission. You'll likely be dropping the transmission to get it out and clean the brake fluid off your clutch disc.



I'd take the slave off regardless, and buy one of those dental mirrors and a small flashlight to see if you can have a look in the bell housing to see if there are any problems.
