Hey, I’m in total despair and really don’t know any more. Maybe one of you has an idea. I drive a Seat Leon Cupra 280 from 2014 with 6-speed manual transmission. A month ago I made my clutch new with ZMS, clutch disc, pressure plate and central release. After the assembly it started that the clutch did not separate any more. Everything aired several times and also here no improvement. Air came out but no more. If the engine is off, it can be al If it is on, then no gear goes in or out. The clutch does not separate wisely. So I removed the gearbox again at the beginning of the week and changed the central trigger again. Also no improvement… As a result I changed the vent valve, the hose to the encoder cylinder and the encoder cylinder itself everything to exclude errors there. Also no improvement. There must be something on the clutch package. When the engine is out, the clutch pedal increases a bit of pressure but also not really. But when the engine is on then the pressure in the pedal is completely gone and if you put it pressure, it stays on the ground. If you put the engine back out, the pressure in the pedal is back again. What else could it be? I’ve already dismantled the gearbox three times and got a little crisis. What else could it be? When the clutch is installed, the K is normally installed. upplungsscheibe centered with the pressure plate and then screwed to the ZMS. Then the central trigger to the gearbox and then everything assembled and ventilated. Clutch set is from Sachs with the manufacturer’s number: 3000 990 350 I am at a loss Thanks already for any help
