Hi,

I just joined this board,

I posted this in a reply to another topic but i wanted to see what everyone knows about the problem

I have this noise when i am at idle, it is a slight kind of knocking/pinging which is low pitched and very quiet

i also have another noise when the air conditioner is on, it is kinda of like a metal rattle, it is quite loud

the third noise i have herd is with the front drivers side suspension, it makes kind or a squishing noise when you go over a bump

BTW: this is a 1997 e320 with almostr 80k miles

are any of these related?

any help would be great

Thanks

anyone?

I know how annoying noises can be.

Here's my guess, while we wait for the experts:

Idling: I can't really define what is "low pitched and very quiet" to really be the problem. Could you describe more in detail?

Air Conditioner On: Try the compressor. Turn the a/c off, and the noise goes off.

Front driver's side suspension: check the tie-rods, suspension or the brakes ...

Just to add to ymsin said: the first noise may be your belt/belt tensioner. If they are the originals, they are gone!
