Has the clutch been changed atall? I had a full rebuild on mine at 120k and it wasn't really needed that badly, TGM reckoned i could have got away with a clutch change only.
I budgeted for the full build so had the lot changed for peice of mind. Synchros hub assembly, new gears and bearings etc, and its the best thing ive done tbh. They changed the clutch at the same time obviously, but something still wasn't right, struggling to engage second etc, and a noise when my foot was off the clutch pedal, so i took it back, Tom changed the clutch again under warranty ( covered about 1000 miles) and it cured everything. All parts were oem too, so very rare for something to be a miss with a new clutch kit but hey, thats just my luck hahaha. Hence why i am suggesting clutch.
But if the clutch is due a renewal then that won't be helping.
could always bleed it with new fluid and see if that helps?
