Default Strange „click“-sound when alternating load

Hello,

I do have a problem with my 2002 C5 A4 Coupe (3.15 rear end).

First it started on a very irregular basis when shifting form “N”eutral to “D”rive or “R”everse. During these circumstances I got a SINGLE “CLICK” – noise which could only be heart with the windows down.

Now I get this SINGLE “CLICK” nearly every time I alter the throttle from idle position (for example rolling 25mph in 2nd at idle then opening the throttle to 30% - one single click). This metallic sounding click can only be heart with the windows down / top down.

It is very hard to locate, however, at least I suppose so, it might come from the rear part of the driveline.

Any ideas?

Thanks’ in advance,
Johannes

The first thing to check would be the axle spline.....or more specifically, the surface between the CV joint hub and hub bearing sticking. You can back off the axle nut, push the axle in slightly, and lube the surface where the hub and bearing interface.

Check this out....
