Rattling noise

Post by Gary(rs4)87 » Fri Aug 23, 2019 3:27 pm

About 2000rpm when I press full throttle rattling noise coming from somewhere. Anyone had this issue before?
Is it can be a pressure plate or the DA flywheel? Or what else?

I vaguely recall a TSB that came out regarding a rattling noise at low rpm and disappears once the rpm increases over roughly 3k. The solution was to re-shim the L/H output flange on the front diff.

Does it have a Forge oil cooler? The early ones made a noise around 1800-2000rpm as there was slight movement in the mount kit.

No I have the oem oil cooler.

About the front diff what you suggest to do?
My mechanic said the noise could be the flywheel.
