when the car is idle with clutch out you can hear like a thumping or slight banging. When you put the clutch down it stops. Is it the throw out bearing. ?

That is probably it. Make sure you get it fixed right away, mine is making a funny sound like a high pitched metal on metal sound. Its the throw out bearing when I installed it I barely set it in there and should have tightened it somehow. Not bad for my first time...

Most likely it is coming from the transmission. Unless the clutch linkage is out of adjustment the clutch release bearing is not turning with the clutch engaged.

The cause could be the throw out bearing or the pilot bearing however the latter is brass so unless it has been damaged somehow I would concentrate on the throw out. The bearing contrary to popular belief does turn, but it is not loaded so any problems would not be as evident. The hydralic mechanize does NOT pull the bearing off of the forks of the clutch pressure plate so there is some contact, in fact if the bearing is badly worn and hard to turn it can wear the forks due to fricton of the bearing on the forks. This as you can imagine it can get really ugly really quick. Pull the trans and inspect for any slop in the fork throw out combo and all the forks on the pressure plate. Any wear can cause problems. A few years back this happened to me, wear on the forks of the pressure plate, only 2-2.5mm or so and the clutch would not release completely at full pedal deflection.

Could be either your throwout bearing, or the transmission input shaft main bearing.
