Hi all.need some advice.my wife was driving my 300 tdi disco and lost drive,not sure what gearbox it is.but reverse is under 5th gear.anyway clutch feels fine,goes in and out of gear,you can also select gear without the clutch (engine running of course).but when you press the clutch down there a horrible grating noise from gearbox.not sure if its clutch or gearbox.first thing I checked was that she she didnt knock it out of hi box.
