2000 Audi A4 repair cost

that would depend on what is being repaired/replaced. clutch master cylinder, clutch lines etc..?

i smelt and saw smoke come out and i cant put the car in gear even with the clutch fully pushed. so is the proplem and what are the cost repairs roughly

what color of smoke and where did it come from?

the smoke color was kind of grey not too dark and it was commin from the engine sides like where the wheels are and some smoke from the front also. i drove it for a bit but i felt the clutch go bit by bit till it completely wont let my put it in gear. i believe the clutch has burned because befor this happened when the car is in first gear it would take of when i reached say the last third of the clutch then the car would move. one time before the same smoke came but the clutch still work or i mean the car would go in gear and it would move. i yopu can explain whit this is and the cost of repair and advice would be greatly appreciated thank you dearly
