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

I wouldn't have the faintest clue on the part numbers. I just had the car towed to the dealership and got it back a couple of days later with my pocket about $1800 lighter.

I agree with post number 15, there are no coolant lines inside the manifold or 'steel braided hoses'.
It would be good to know if these modded hoses do actually exist.

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

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.

If you have tasted it you would know whether it was coolant or not, coolant is very sweet to the taste, I'm not sure where the a/c loses it's condensation from, maybe this is it? Best to lift it up and have a look around, check your levels etc, so you won't have a failure down the road.
Bad idea to ingest POISON!

If you die from tasting (not swallowing here) a very small amount of whats there to determine what it is then you were headed for the ground already... You can spit it out as soon as your taste buds tell you whats going on, just my thoughts as it sometimes is hard to tell what it is if it's diluted.

How Does One Know ? Where to Look ?
If you open the hood, its all engine covers and side covers. As I've recently picked mine up, I'd like to know where's the quickest place to check if mine are plastic time bombs or Metal !

Well, someone posted otherwise, but I have always been told you have to take the top of the manifold off to expose the pipes running within...

Bought my Cayenne 04 last week, and I just wan´t to say, what a big help all of you have been already. Definately going to check the pipes and change / have them changed asap if plastic. 1kEur is small money to avoid further disaster, leaking coolants in the middle of no where. Thanks!

If it was serviced/repaired at a Porsche dealership ever they would be able to tell you if it has been performed. They use a borescope to verify the leak when it occurs so I'm guessing the pipes are not visible from above the manifold.

Yipes....I only paid $952 from my dealer. Of course, I also paid $700 for water pump so maybe they felt bad...hah

The intake manifold has to be removed to see the actual coolant pipes??
