    Problem with clutch a3 8p

    Hello everyone, maybe someone will help me here, for which I would be grateful. The problem concerns my Audi a3 8p 2.0 tfsi Quattro, the problem is that it does not always bounce back the clutch, I have already replaced 2x complete clutch with dual mass, 3x clutch pumps and spring pedal clutch, and yet the problem is still the same, maybe someone had a similar symptom? I have no idea what the reason may be ... I will be grateful for any suggestions. Regards.

    Hi, does it happen when you drive a left turn?

    Rather, it doesn't make a difference, sometimes it can do it even when stationary.

    What if I turn left? Maybe it's worth checking it out.

    Well be happy if not... it could meen thet the main crankshaft bearing has too much play (axial). In the case of a left-hand curve, the crankshaft moves to the right, which creates greater play on the release bearing. I had had that problem more then once in my 27 years working for Audi and VW.
    It also could be the pressure hose, there was a bulletin from Audi years ago. It says that the hose can "swell" inside, in that case the fluid goes in one direction (under pressure when you press the clutch)
    but does not flow back fast enough. So the pedal wont go back on its own. Sometimes the clutch can also slip for a few seconds if you accelerate hard after gear change.

    it could also be that there is still air in the system. You can use another option for bleeding, connect the front left brake caliper with a silicone hose to the clutch cylinder, bleed the hose, open both valves and slowly pump the fluid with the brakepedal backwards through the clutch cylinder into the expansion tank, this creates a circuit and the air can go up.

    I will try to buy this rubber hose, it can help. When I had the chest, the gap on the chest was loose, but only longitudinally.

    I will order a new hose, replace it and let you know. Thanks for the help.

    Since this appears to involve a manual transmission and clutch, with which VCDS is no help at all, I'm moving this to General VW/Audi Repair.

    Ahhhh did you know crank thrust washers can be dropped or add shims with crank in vehicle if required to establish end play?

    Grease on slider for throw out okay?

    Ever consider a return spring be installed or shim or use longer throw of bearing or if correct established height of plate to bearing is proper from incorrect FOD parts installed and possibly unwittingly?

    Hm, everything was put on as it should, especially since I bought 2 clutch because I thought that the first one could be faulty. I was mounting the spring on the pedal but after all, when the pedal was not reflecting there was a problem with shifting the gear.

    The symptom is as if the pressure in the system disappeared for a moment, the reason may be this hose, as a colleague mentioned above, I will try to replace it, it may help ...

    Yes the hose is possible it's a TSB is it not?

    Not the pedal, the throw out bearing fork for helper spring?

    So maybe you bought the wrong clutch or stuff was boxed up wrong twice?

    Did you measure all the old parts and compare the heights with proper tools?
