Please contribute - coolant pipe failure data collection

[xsrfs]

I haven't seen anything like this. I'm collecting data on coolant pipe failure and tracking it. This stems from my own curiousity but maybe it will show some good results. I have the same thread on 6speed at http://www.6speedonline.com/forums/cayenne/251205-coolant-pipe-data-points-please-contribute.html It doesn't matter - Post here or there

Please include Model, Model year, date of failure, mileage at failure, and location

Thanks!

I will be starting this job tomorrow on my fathers 04 Cayenne S. Just bought the whole replacement kit from Porsche UK.

Did they fail? Or this a preventative measure?

Why do you want to track this data?

[xsrfs]

Driven by curiosity. I'm an engineer and like to plot data. I'm curious if trends more to location, age, mileage, CS vs CTT, etc

This was a failure in my case - thats the only reason I discovered about this common problem. 70k miles on a 2004 Cayenne S.

so i´m in this company as well...mine got the same problem at previous week at my 05CTT , 90k.

Mine were already replaced when I bought it, no idea if it was preventative or failure, but I assume it was from failure since the car only had 49k on it, and it's been driven exclusively in hot southern states.

I did mine preventatively. It looked fine when I took the old one out (as in no signs of cracking anytime soon). 2004 CS with 55k miles California car.

I got mine with 71,000 miles on it and the major coolant pipe service had been completed. Car was in Hawaii most of its life with a year or so in Oregon. The rear engine exterior coolant pipes failed around 69,000 miles and were replaced by the previous owner as well. 2005 CTT.
