Sound from 300TDI
Hi all,

New to this forum and have had my 110 300 tdi csw for almost 48 hours now.....

Would anyone be able to help identify the source of this noise coming from the engine?

It increases with RPM. My first guess was a belt but worried it could be a bearing. Car was just driven 150 miles from Spain by former owner who claimed the sound was present the entire time.

I posted 2 videos to youtube as I could not find a way to upload here.

Belt tensioner would be a starter to check. Sounds like drive belt derived noise.

Yep. I’m not hearing enything that particularly worries me. It is a Landy. It’ll keep going. It’s just telling you it wants some of your money and time. Thumbs Up

Just double check the crank pulley. I had a squeak which I thought was the tensioner. On replacing it I noticed the crank pulley was wobbly. Rubber damper had collapsed in it - if so replace ASAP as it'll snap the crank (having snapped done two I think I know)... Ed

@sako243 thanks for your reply! Where would this be located? It sounds as tho the noise is coming from the front left hand side of the engine. Mine is a LHD if that makes any difference?

@Landy Andy; hope you are right Very Happy

cheers!

Big pulley at the bottom of the engine. One big (24 or 27mm, can't remember off the top of my head) bolt holding it on. Easier to have a look from underneath.

If there's rubber dust around it I'd be concerned as well. New pulleys aren't dear but easier to replace with the radiator out. Ed
