Hey I am ordering rear brakes for my 04' Cayenne S. Does anyone know if its 350mm or 380mm? Vin is WP1AB29P04LA66223. Thanks!

I think this was the problem. My mechanic ripped it apart again under duress and found quite a bit of residue. He cleaned it and has kept the car for three days, pressure checked, and driven it himself and no coolant smell. So let's hope thats it. Thanks

If the "V" between the cylinder wasn't cleaned properly of the old coolant it could take ages for the residue to disappear. The water pump is also a source of leaks so get that inspected.

The didn't say and the conversation turned South, quickly yet I felt the person I was talking to was sincere so I would try hold out for some assistance. Good luck!

Well i took my car yesterday to the mechanic due to heavy coolant leakage. After diagnosing the problem, he assured me that it needed the coolant pipes kit and it is going to cost around 2300 for the repair. I knew that mod was pricey but not that pricey. So i took the car to another mechanic. Waiting for the verdict. What kind of assistance is Porsche USA providing ?

Cayenne 2004 S.

GROAN. So after shelling out $1400 to have the coolant design problem fixed with upgraded SS, I still have the same problem I had to begin with. I was smelling coolant at stops when the windows are down. After researching I was (along with my mechanic) convinced that the upgrade per TSB would fix this. Well 6 weeks later and still the smell of coolant and now check engine light (code is for throttle body). WTF? No visible leakage. Biggest frustration being that Porsche USA just called after I left them a gnarly review. They are now saying I should of called them as they provide "good-will assistance". So anyone that hasn't had this problem fixed duly note this. Yet they won't reimburse for repairs already tendered. :wacko:

A little yes

So bad month for my 2004 Cayenne S with 32k miles. Coolant problem fixed ($1,400) Drive shaft fixed ($1170) and now the starter is making strange after start grinding noise. I am out of warranty and thinking I should dump this car before I blow up another Visa card. Is the starter known to fail on these? I can't find anything in the forums about starter issues. Also is it worth sending Porsche a letter re: known problems with coolant design flaw and crappy drive shaft? Wondering if it's a waste of paper.
