just got the car up running a few days ago and everythign was all and well for its first 100 mile drive or so, engaged sturdy, ran/drove fine etc. The car then sat for a day, and I got in it yesterday to go for another run and the car will idle and start just fine, but when i engage the clutch to put it into gear it pulls the revs down and stalls.

If I press the clutch lightly(not enough to engage) you can feel it start to pull the revs down, harder you press the harder it pulls them down.

I am not overextending the pressureplate(pedal stop) and you can feel where the pedal "seats" into position when engaged. That point is exactly where I am engaging the clutch to. Not sure what the issue might be, but its certainly not good.

Any insight?

Did you bleed the clutch enough? Try rebleeding the system.

Did you install a new throw-out bearing with the clutch?

yup, it engages right at the top of the travel, and yes the CM throwout is in there.

it worked fine for the first day. i loved the feel/drivability really.... then next time i started it it did this.

What exactly is it doing? Does it stall after you put it in gear, or only as you step on the pedal? If it's not engaging when you put it in gear until you are almost all the way up on the pedal, then it could use a re-bleed.

it stalls down as you push in the clutch pedal, in neutral.

Thank you. Wow, this is a head scratcher since I have never seen a car do this before. Did you have the transmission out also, or have it drained? If it was empty, did you refill it? (I now that was probably a stupid question, but I've seen it before) You definitely never had this problem before, or any problems with the trans? Any more information you could give me would help greatly.

new car to me, never drove it before the build. Fresh trans fluid etc.

Everything drove and engaged just fine on the first few days, not quite getting it. The logic of what is happening makes absolutely no sense to me.

I have been an Audi specialist for over ten years now and I can only see two things it might be. The problems could be: the intermediate shaft inside the trans is binding up(which is pretty unlikely), or the clutch itself. The pressure plate could have been left loose, or could have come loose. Make sure to put threadlocker on the bolts holding the pessure plate to the flywheel. I would check that first. I hope I was some help to you, and feel free to ask me anything in the future, I'm on here to try to help people with my knowledge. Good day.

i'll prob end up pulling the trans tonight/tomorrow. Pressure plate bolts are ARP's w/red threadlock on them. Thanks.

I hope I helped you out. When you pull the trans out, try spinning the input shaft, if it turns somewhat freely then it's the clutch. The clamp pressure could be too much for the throwout bearing to release and it's binding up the bearing and stalling the engine out. That's about all it can be.

i cant see this being an issue, as the clutch came as an engineered kit. the TOB was included in this kit.

Yeah the clamping pressure is not an issue since the twin plates use way less pressure then a standard preformance clutch since the twin plate uses more surface area on multiple disks to create hold

Since you said it happens even if the car is in neutral my guess would be that the TOB failed causing resistance to the engine since the TOB is connected to the fork which is not going to move. A clutch issue or bad pilot bearing wouldn't cause the problem while in neutral, unless clutch setup has come loose and is hitting the bell housing but I am sure you would hear that.

TOB was all i could come up with, also.... which would make a nice shiny ring on the fingers where it contacts.

Check the TOB and make sure the machined adapter did not separate from the TOB during install, also the splines need to be lined up perfectly during the install, if they were binding, one of the clutch disks may have bent slightly.

Haenszel20v

so......... pulled everything apart....... and it all looks fine. All disks sit flat on eachother, TOB is seemingly fine, still together....

Whats next?

Yeah, check the pressure plate fingers for a shiny ring, that would mean the TOB is binding up. Check the face of the TOB and make sure it spins freely, also check the inside of the bellhousing, just to be sure nothing was contacting the inside of it. That's about all I can think of, sorry if it's no help man.

There's a shiny ring, but if I remember all clutches i've ever pulled have that? Throw out bearing spins freely for me, although under load it could certainly cause issue.

No marks on the clutch, pressure plate, or bellhousing.

Verified on my roommates s4 we just pulled out yesterday --- his has a ring on the PP fingers too, and it drove fine.

after 20k miles they have that, not normally after 100 miles.

its not a huge shiny ring like "oh man this thing's super ground down and machined itself" -- its so faint that I can't even take a picture of it.

fatjohnperf
06-28-2009, 11:04 AM
Ghost is correct, I was just going to tell you that. The shiny ring is only made after thousands of miles, not after just a few hundred. There is definitely a problem with that TOB. Try changing it out with a new one. And take the clutch back off the engine and check the plates for straightness, you can't tell if they are flat when they are installed because of the pressure plate clamp pressure on it would hold the disks flat.

is there a way you can bolt it to something and actuate the fingers to verify release of discs? even leaving it on the FW, and someway push the PP fingers to check for operation?

Haenszel20v

speeding-g60, can you take a pic of your 01a/01e throw out bearing they sent you for me?

But even if the disks were not releasing the still wouldn't cause his problems seeing that it happens in neutral which means even if the input shaft of the transmission is turning its not putting any resistance on the motor since its not connecting to the driveline. Something is putting resistance on the actual flywheel/pressure plate top causing the motor to bog down.

so what do you think it is then, since there's no scraping/griding, and everythign seems to spin freely?

Since it is all apart, just toss a stock clutch in and see if the symptoms are still there,

I don't have any of that fanciness, sadly. This is my first a4 clutch.

My apologies then. The only things that would bind would be the disks or bearings.

you dont have the clutch that came with the car still?

mike-2ptzero
06-28-2009, 04:53 PM
yeah putting in a stock or standard clutch right now is the only way to figure out if it is a clutch or transmission issue.

Haenszel20v

nah it was, lets say.... slightly "unbalanced".

thats right. FW comes loose, rattles all the shit to death. i forgot. must have home-slotted bolt holes now n stuff....

i dont have anything to send to help ya with this time. sorry....

anyone else have a stock setup Brian can borrow to help him get this sorted?
