2003 Cayenne S noise?

[moosey]

I have a 2003 Cayenne S tiptronic, when braking hard from about 50mph I get a sound noise like thud coming from the trans i believe. It has about 66K miles on it and never had any problem with the car at all. Or is this normal when the car is down shifting hard during deceleration?

I notice a loud clunk or thud at times from both my '06 and '08 when slowing the vehicle aggressively. It is intermittent...doesn't happen all the time, and only when I'm in automatic (not tiptronic mode).

Have you always noticed this or did you just start noticing the thud recently? When you're in automatic or tiptronic? Based on my experience, I don't think what you're hearing is abnormal if you're driving with the transmission in automatic and not tip.

Those on the board with a 2003 model year might have further input as to what you are hearing is normal or not.

Bill - I never hear when in ip mode, bu i do get the noise when in normal auto mode. I have noticed this on and off for about a year.

Same situation for me...I hope this in normal for us. The Cayenne's are a great ride! I never thought much about the downshift thug until you posted...now you've heightened my awareness.

All the best,

I had the same problem, however shortly after (some 2 weeks of noise) my centre bearing has torn away from the rubber mount, I now need a new Propshaft at £600 plus fitting - beware!! Porsche are one of the very few that don't supply a Centre bearing? wonder why at new prop prices of £600 +....
