Maybe this or a similar thread exists already but i searched and can't find it. I have an 04 CS that I picked up a few months ago. She now has 27k mi, i got with 24k. I was forwarded a thread on how to tell if your's had the coolant pipes replaced yet because I don't know for mine. The following idea isn't justifying replacement or not, but rather just to collect some data points.Between age and mileage which is a heavier contributor to failure? I.e. will this always happen at ~60kmi regardless of age or maybe it happens after 4 years no matter the mileage. I'm sure its a combination of both buts lets plot it.Please reply with model year, approx date of coolant pipe failure, and mileage at failure.

Thanks but that's not what I'm requesting. I already have that. I'm looking for users' individual data regarding failure vs. mileage and age

 

2005 Cayenne Turbo, just hit 76k miles and she blew 7-27-11

 

2004 CTT failed at 70k 7/2010

 

so between 70-76k if it is July, watch out!!!! haha

 

You know, what I should probably add in Location too. July is way worse in Texas than in San Diego, etc

 

Cole and I are both in Colorado

 

Minie actually burst right at the top of Loveland pass too

Ironically, I was running "Sweep" for a PCA club drive

Three adults and two large dogs ended up riding all the way back to Denver in a Porsche 951

(BTW, I saw your CTT sitting at 3Zero3 today)

 

nice, how'd she look? The parts just showed up today so Palmer is trying to get the Porsche tech's on it asap so I can get it back. I want to go to bandimere next Wed to see how much mph I'm picking up with the exhaust, lighter wheels, etc.

 

Palmer looked pretty good Especially after I got my hug


No idea how your CTT looked after that

 

2006 CTT 35,000 miles . Haven't had a problem yet, live in Chicagoland area. I have had the Cayenne for a year ,it was originally bought in NW Ohio. Best price I found for replacement is in Oaklawn, Il . $1275.00 includes everything in the kit from Porsche even the Tee at the back of the engine. Best price on front brakes too, unless you DIY $775.00 includes pads and rotors. I am considering getting the pipes done just for peace of mind. I think the price is reasonable enough

 

Replaced the pipes at 50K miles as a preventive measure. After they took it apart, they found the seals were already dripping. Basically there are several things that can leak:
1) Plastic coolant pipes
2) T at the back
3) Seals
I got them all replaced in one job. It's gotta be done, the sooner the better if you plan to keep your car for a while.

 

2005 CTT with coolant pipes replaced by dealer at around 65,000 miles.

 

2006 Titanium Cayenne S, had her from 9miles, pipes failed @ 79.4K 7/22/11.... lower pipe cracked/burst one block from home....
