How important is the coolant pipe upgrade on an 04 Cayenne TT?
Curious as to when Porsche decides this is a design error and decides a recall; seems alot of people with v-8s are having to do this?? are recalls more on a safety issue rather than mechanical failure??

I believe he is refering to under the intake manifold?
I don't believe this is an official recall. (at least that's what I was informed from my local P-dealer.) If you guys know the ref# of this recall, please let me know.
Just out of curiosity, mine was built in Oct of 06, do you think mine has the plastic or aluminum ones? Is it possible to visually check?

Another thing to check out (as I found out recently) is there are two plastic coolant lines inside the intake manifold. These can also crack. Ask me how I know! 100% of my coolant basically went into the manifold and straight out my exhaust while crusing at 70mph on the hwy. Poor sucka behind me didn't know what happened when all of a sudden his windshield was drenched in coolant and water.
I was out of warranty and it cost $2k to fix and upgrade the pieces to the new steel-braided versions. I'm still pissed and think it should have been a recall fix but I guess not quite enough have failed to recall...though enough so that they upgraded the part!

I was going 15mph coming up to a stop light and my entire coolant just dropped. Just got off the phone w/ porsche and obviously they don't stand by their product. They completely upgrade the coolant system from a three-pipe plastic to a 2 pipe metal (have to use a saw to cut out the old plastic pipes) and they will not admit that they had faulty engineering. From a brand like Porsche this is unacceptable and with the service I just received from them on this matter will question my next purchase
Would I buy these cars again knowing these issue? In a heartbeat.

Get ready for spark plugs, coils, cardan shaft too bub.
Sorry you found out the hardway.......check out rennlist too.
How much was that?
Be forewarned, if you wait till the pipes burst and coolant covers the motor and transmission you can have more expensive repairs later. When mine went it took with it the transmission seals 48 hours later and I was told by the dealer that since the starter is right under the pipes it usually will fail shortly after as well.
Yep! my starter failed due to the leak, took few months, thought I had a weak battery?

Yikes! Mine burst about 18 months ago and I haven't had any issues with the tranny or starter yet.

Can you advise us of the part numbers for the manifold coolant lines that failed inside your intake manifold.

The part numbers of the replacement new steel braided lines you had fitted would be good to know of as well.

Thanks.
Based on some posts above is this ussually/always a dump of coolant or can it start out slow? I noticed on my 47k mile 06S that there have been small trailing puddles under my car the last 3 days inside of the left front passenger tire (about 1 1/2 feet from the tire). Doesn't taste or look like coolant (it's clear and relatively odor free) but it hasn't been there before. Any thoughts? I drive quite a bit and don't want my family and I stranded on the side of the road during the holidays.
Thanks
Thanks
^What is the average labor cost on this.
Can you ever get a Porsche dealer to do this Pro Bono, seems to be a pretty widespread issue. Should be a recall............I have seen this kinda crap on most
Manufacturers.
