VW are due to finish fixing the car today. They said is was not the hydraulics. The clutch was completely burned out, but I think that was the cause of a problem in the gearbox, which caused it no to engage properly and smoke the clutch majorly. It stank. Anyway, they had to take the whole gearbox out, and have had to replace the flywheel as well, as it was in a bit of a mess?, which seems as thought the gearbox did has something majorly wrong with it. As it has been through normal driving the guy said it should be on the warranty.
