Audi A6 2005 - New Duel mass and clutch kit fitted making noises - Daniel Wade

Hi all, I am wondering if anyone can help. I have put a new clutch in my Audi A6 while I was on I did the Duel mass flywheel and the clutch slave cylinder replaced the brake fluid (as it shares a tank with the clutch slave cylinder) and blead the brakes and the new slave cylinder. When the car runs at idol it sounds like a squeeky/ grinding mettle on mettle noise when dipping the clutch and putting it in gear the noise remains but gears do select and wheels turn. The clutch peddle doesn't feel like it's doing anything untill half way pressed down. I must have done something wrong but any suggestions are welcome many thanx

Metal on metal when dipping the clutch sounds like a slave cylinder/release bearing issue (presuming it's a concentric one inside gearbox) especially if the pedal doesn't seem right as well. I'm afraid it sounds as though you need to take the gearbox off again to investigate. The metal on metal contact should hopefully be obvious by marks on the offending items.

Don't ignore it as the metal to metal noise might be onto something expensive such as the gearbox casing.

Thank you, I was thinking it's a box off job again. The noise is constant if in nutural or in gear. I forgot to say earlier the car is front wheel drive (not quattro) and is 55 plate TDI

I would check to see if you have fitted the clutch friction plate the correct way round. There should be markings on it to show which face goes to engine side.

Yup, been there done that on a Ford Zodiac MKIV(long long ago...) - thinking about it the pedal ended up in the wrong position with that one!

Whatever - it's a box off job sadly, second time is usually easier and quicker though! When in bits - whatever the issue is check the slave cylinder/thrust bearing unit is 100% and not damaged, any doubt just fit a new one(relatively cheap)! They are known to fail and then contaminate the clutch pressure plate and you don't want gearbox off practice for a third time!
