Hi,

After the last A service on my 1998 E320 by the dealer I started hearing this clicking sound from the engine when the engine was "idle" (in park or in D, but no acceleration). So, I took it to the dealer last night and now they are saying that the spring inside the main belt tensioner is broken. The replacement parts and labor are about $450. Is this something that a normal mehanic would be able to replace more economically or is their price reasonable for the job? Any ideas what this part might be?

Thanks!

Should I go with the OEM one that is "updated version" or stick to the alternate brand (presumably "older version")?

with the updated oem version The other might be just fine but the oem updated is worry free.
Order a new belt at the same time the old one probably could use changin
