Coupling change 1.4TDI

It was just in a workshop because of my clutch. Conclusion. It is closed after 120000km. The wanted to have 250€ for the installation. I have already purchased a LUK rep set, and just need a mounting. Has someone from you changed the clutch on a 1.4TDI AMF engine before? If yes, can write me a short instruction with the problems that occur etc. Although I bought “so is done” and screw everything itself just the clutch makes me worry. Is it even from a layman to change? I would of course have support from a fellow student, who did a car training at VW. Just a training. But it is not too sure anymore…. Finding a suitable workshop is also no problem with us, here there are well equipped rental workshops at every corner. Thanks for every comment!
