if the tensioner had gone ford advise replacing pully as well
FORD TSB
Should a customer express concern about a drumming noise from the accessory drive belt with the engine at idle, the probable cause is a high accessory drive belt excitation caused by crankshaft vibration being transmitted into the accessory drive belt drive. The drumming noise only occurs during idle and should disappear at engine speeds above 1000 rpm.
To rectify this concern a revised crankshaft
pulley together with a new accessory drive belt and accessory drive belt tensioner MUST be installed, without exception. The reason for replacing the accessory drive belt and the accessory drive belt tensioner is because they will both deteriorate after prolonged exposure to belt flap.

thats why they are usually sold as a complete kit

how can u locate this noise. sorry to be a bit stupid but this is my first diesal and its perfect but for the diesal noise which i still cant get used to. i did notice that a ford dealer put anew belt tensioner on the car back in 2008. and it does sound a bit louder on idle than my inlaws freelander diesal. i have put it down to duratorque having a chain rather than a belt though.

I have exactly the same noise mate, mine a 2004 TDCi 130bhp 68k,
I changed the belt and tensioner pulley which might have quitened it but its still there more to the side of the air con pulley...?
I have also had people say 'ar its a diesel they do that'... But being my 6th diesel car 3 vauxhalls and 2 peugeots and 1 escort td, i havent herad them make noise like this and half of them was chain driven and other half belt....!
Let me know if the famous crank shaft pulley (a.k.a dampaner pulley)cures this problem or its another waste of money like the tensioner.....

Probably not belt related if the noise stops when the clutch is down. Could be DMF on it's way out :(

Mine doesnt make any difference to the noise - clutch in - clutch out, lights on/off, air con on/off....etc etc...
Driving me mad as said before changed the belt and tensioner pulley, its noisier near the air con pulley but its hard to pin point with the engine noise aswell.
What is the difference in a modified crankshaft pulley anyone have pics of the 2, and do these crankshaft pulleys have a bearing system inside? one bloke reffered to them as a dampener pulley...?
DRIVING ME MAD.....Ahhhhh
it wont be long before its up for sale l.o.l....

Mine also does this with the aircon on, stops once its switched off though.

However there is a constant noise that switched on and off regularly as if its charging an accumulator or something.

Its due a service soon anyway so I guess i'd better check the balts and tensioners, will do that whilst rebuilding the front end (see my other post :( )

Had this problem -Knocking noise - with air con on - that went away when off - so took to ford "specialist" who changed the tensioner pulley ONLY. Rubber bush was knackered in pulley assembly

Cured the on / off noise but.... from what I read here they "should" have changed crank shaft pulley also - while they were there...

now it has recently developed a " phat phat" noise at low revs / high load - blowing exhaust??

there is a very common problem with the crank pulley which worsens when the engines under load, eg. aircon on. its two metal parts joined together by rubber, i dont know what difference this makes. but ford replace the tensioner, belt and crank pulley all at once as the wobbling from the pulley damages the belt and tensioner. i'd replace the pulley anyway.

I've noticed mine getting noisier at low revs but thought it was just 'diesel clatter'. I changed the tensioner pulley and belt about 6k miles ago as it was driving me nuts at idle. I noticed most duratorqs sound the same. When I changed the pulley and belt I had a 'mare' getting the tensioner off. Do Ford use a special tool with 1/2'' drive for this? The manual says use a 1/2'' drive to back off the tensioner but there's no room between the chassis/body and tensioner to get one in?? I would change the bottom pulley but it's too difficult to get the tension off to remove the belt. :(
