Occasional clutch problems


New Member
I have an 05 plate a3 2ltr tdi, s-line.
Question for those in the know ....
Occasionally gets stuck in 1st gear, but does release after dipping clutch again.
Also occasionally feels like a sticky pedal when coming OUT of 3rd gear.
She is engaging fully and smoothly and clutch is not slipping and no odd or horrid noises.
Question is ... Has anyone come across this before and if so what was the problem and what do I do about it?
Please help as its doin my nut in
