My 300tdi has always had a very slightly noisy fan belt when cold ever since i have had it, when it warms up its fine.
The last couple of days it has got progressivly louder and persistent so that now it squeals all the time.
Having just been under it i assumed the tensioner was at fault and so replaced it,no change :evil:  so delve deeper and it now looks like the power steering pump pulley has moved out of alignment about 5 mm or so causing the belt to rub hard against one of the edges of the pulley, this is whats causing the squealing.
Looking from under the car you can just make out a shiny surface on the shaft which indicates to me the shaft is attempting to move out of the pump, this is not good :(  least of all for my wallet.
Has anyone else had this as i,m assuming the pump has worn internally to the point of near failure although the steering shows no sign of anything wrong although the steering box has a leak from the lower seal as well which has now got worse.
I think i,m going to have to replace the pump and the steering box which i could well do without at this time of year

any thoughts as i,m now thoroughly fed up

Have a look on ebay for a pump, I picked a good one up for £8 a year ago !

My air con compressor pulley is very very slightly out of line, mine produces a small high pitched whine.  I have kept it as is though as haveing a V8 it sounds like I have a turbo fitted :)

beast5680:
just been looking at parts suppliers for prices etc not exactly consistent are they found one with a steering box for £800ish :shock:

robbie:
I am in a similar boat at the moment as I have a fluid leak from somewhere near the pump, not sure if it is a pipe, or the pump itself.

I found one on Paddocks for around £80 plus VAT and delivery

I have also used them before and found their prices to be very competitive.

Oh, and mines a 300TDi too ;)

I posted the same question on the forum on Sunday but my 1996 300 TDi disco is shredding it's serpentine belt.

I also eventually traced it to the power steering pump. Looks as though the shaft has moved out of the pump body by approx. 5mm+ causing the lip on the pulley to shred the belt.

At present i am running without a fan so it gave me room to use a hammer to tap the pulley/shaft, everything moved back into it's correct position.

Had to tap back into correct position twice in the last month. I am carrying a spare belt at the moment and check the pump position once a week.

Have heard that on a 200 series the pump is servicable but not on the 300 series. Maybe someone out there knows? Would like to remove the pump to investigate but can't do without vehicle at moment(needed for work & the dreaded Christmas shopping).

Will be watching the forum for responses. Maybe Santa will leave one under the tree for me!! If not i may end up buying one from Paddocks in the new year, about £85 ish.

Good luck
