1981 240D clutch problem
So i think my clutch is on its last leg. The clutch has been fine and tight in the past months, but this morning it started to slip. I can still drive the car just cant accelerate fast since the clutch will start to slip. This happened over night the clutch feeling tight to going to slip. It also does not pop back up like it should. Seems like it sticks a little and then come back up. I wonder if the master cylinder has anything to do with that or if the clutch is toast. If so where is the cylinder even located so i can bleed it a little bit maybe.

From your description, it sounds as if it might be possible that the slave cylinder is not completely returning to the rest position after the clutch is disengaged. I'd jack it up and get under the car to observe what happens as someone else disengages and engages the clutch.

From the description it sounds like it could be the throwout bearing. It slides on a shaft that is around the input shaft to the transmission. Since these cars really only saw grease at the factory, the throwout bearing can bind on the shaft and not release completely.
I was pulling a low mile BMW transmission that had this problem, turns out it was the reason that car came to the junk yard in the first place. The only was to check is to drop the transmission, a <2 hour job on the 240 if you know what your doing.

There is a 'go, no gauge' to measure your clutch wear from the inside of the engine compartment...

Sounds like a hydraulic problem to me. Usually when a clutch wears out you can't get it into gear or get grinding, not slipping. I would try what kerry suggested. Also check the brake fluid reservior, the brakes and clutch share the same res. Make sure you have enough fluid, and make sure both chambers in the res. are full.

the odometer says 180K. but I am not sure if that is the correct mileage, since the motor has a lot of blow by. But it does start here in NH cold mornings without any problems. It is my daily driver.

Any results for us? I have a 240d with 289K. My clutch pedal was flat this morning. I realize that it's been years since I checked my brake fluid, and the level is currently at the min line, allowed air in... hope that's the only problem. I replaced the throwout bearing etc when I changed motors about 4 years ago... hope it's not that. What was wrong with yours?

First thing after checking the brake fluid reservoir I would pull down the carpet between the pedals and feel to see if the hard line to the clutch master is wet. The slave is harder to diagnose unless its leaking all over the ground but the good news is, its easy and cheap to change. I would want to be reasonably sure its not the hydraulics before I pulled the tranny.

Well, I have not had time to look into it further. I have been on business trips the past couple weeks. But I did try to pump the pedal before taking off and also pumping while going down hills and whenever I can during shifting and at times it stops slipping and works just fine. So i can say that the pumping has definitely helped. I also did check the reservoir and there was enough oil in it. I will take a look over the weekend and check the lines and cylinders.
