Decided to hang onto the car for 6 months so im putting the parts back on!! Still selling the tv tuner etc though

Just spoke to local Audi about the clutch slipping and they said bring it in Friday, i asked when they would be able to do the repair as the other dealers i called said they would have to have a look 1st and this Audi said it would be done on the day and would order the parts today

So im just wondering, I have a sachs clutch ready to go on, would they fit that instead of the OEM is I asked?
