    Question Clutch slipping... also replace flywheel?

    Hey guys!

    2 days ago I started to notice my revs jumping 300-400rpm above 4k in 3rd or 4th gear at full power. Since then i've been driving a little grandma'ish!

    At 46,000km I guess my APR stage II finally took its toll on the clutch!

    So I've ordered myself a Sachs SRE Performance Clutch plate and cover but decided not to go with the SMF as i don't track often and want to avoid any idle roughness.

    Question is... is it necessary to replace the OEM DMF?

    When you get the flywheel exposed, you need to check for surface wear / marking - and then there is a certain measurement on the movement in the flywheel. Make sure it meets that spec.

    I'll see if I can find it for you.

    So is it basically a 'given' that once you start modifying (to a stage 2+), the OEM clutch is going to give way imminently?

    Has Audi improved the clutch in the 8PA range at all or are all S3s the same?

    Something i should be budgeting for not long after I have modified?

    Clutch clamping force is what you need to handle torque, unfortunately wear & tear is a bigger factor - AND operator use also a big factor.

    I have tons of customers with stage 2 + on S3's - never had clutch issues, but I know people with standard cars who have (driving habits!)

    This is reassuring to know.
    Thanks Guy.

    If I don't partake in the old traffic light GP, hopefully mine holds up.

    Thanks Guy!

    It actually turns out it may not be the clutch that's giving me problems. So i might have bought the Sachs clutch for nothing (at the moment :P)
    The rpms jump 200-300 rpms down, not up... I dont know what made me think it was the clutch (maybe the loss of power)

    I've hooked up my VCDS and after taking it for a few runs, it looks like the throttle body angle closes a small amount just before i see that rpm drop.
    I havent figured out what could be causing that to happen yet but will log a few more runs.

    Anything you might suggest would be useful to log?

    Might pay to check the clutch pedal switch activation!
