Hmm, as in title, driving along and heard the tell-tale slap of rubber against metal (ooo-err) and the aux belt on my 300tdi Disco has partly shredded. Can't understand why as it was in good condition. Any ideas?
300tdi Auxiliary Belt Shredded

Now and again they wear out...
Water pump bearing collapse pulls the pulley forward at an angle ripping it to bits.
Triple check it, as it can be fatal
Something doesn't quite look right, the belt doesn't seem to be running evenly across all the pulleys (ie nearer to the edge on some, particularly a large pulley low down).
Will take it in to SP as no time to sort myself as it's hopefully getting some action this weekend!
If it regularly sees action then it could be crud in the water you wade. I had this with the 110 after a trip to KORC off road centre. Wading streams never provided a problem apart from the odd squished rare specimen of scientific interest (apparently!). Once a belt has a nick in it it will soon shred its self.

Check the power steering pump pulley, it moves forward (or rather the shaft moves forward out of the pump) and slowly shreds the belt, new pump needed if this is the case. Mine did this 6 months ago. Andrew
Mine went the same as Andrews. With the belt off I could move the power steering pump pulley in and out of the pump body. New pump I'm afraid. Think I paid about =A380 for a new pump (pattern) and it's a pretty easy change.

I had exactly the same problem. Turned out to be the water pump spindle slipping out of the bearing as above. The pulley was sitting forward and the belt was out of alignment. I didn't figure it out until the spindle fell out and the belt shredded. Replacement water pump and new belt fixed it.

It happened to me... about 2000 kms from home... (300Tdi 'fender)
...and it was a *new* water pump (< 2 months old) too.
Weirdest bit... belt jumped 'track', slicing a perfect strip of belt off. Elegant, but still not nice :)
Check belts... if slightest doubt... replace, IMO. I now replace belts at half the recommended, and carry a full set of belts (and a water pump) onboard as a precautionary measure. Probably should have done this anyway, of course.
Check Alternator too, also that bar steward belt tensioner!

I've known an alternator sieze solid on one of those.

Well someone guessed right, the power steering pump is goosed and the spindle has come right forward.
New pump and belt being fitted tomorrow!
Get the water pump- done at same time matey.
Any particular reason or is it just a labour saver?
They are s*it, they go all the time & you might as well for £35, get the gasket & new bolts too, also change the tensioner.
