lol all you want, my engine noise was properly diagnosed on this blog.

Hmmmm, I have a very similar sound emanating from my other German roadster. I thought it might be coming from my wheel spacers, my 2 piece wheels are a little out of round, usually I can loosen then re-torque the wheel nuts and the sound would go away for a while... however after reading all this I'll have to have my mechanic investigate the pinion gear & ring gears.

WAZZ up fixed hommie ?

What was/is it?

he never call or writes

fwiw, my issue is related the wheel spacers. I need to occasionally pull the wheel & spacers off. clean everything up, reinstall and torque everything back down.

still unresolved although right now the smart money is on cv joint + rear lower control arm. will repost when I have definitive answers.

the sound is both constant and intermittent. it got cold here and the sound disappeared entirely for a week. fwiw, moving the cvj axle manually also impacted the noise.

Good luck with the fix.

any update on fix
 

I have a new to me 01 Boxster S and this same sounding noise just popped up at a track day. It even persisted when being towed in not under power. Once we looked around underneath but did not find anything obvious. Put it back together and cannot replicate sound. Would be of great help to trouble shoot this.
