Out of the 20k 996tt's out there seems like an overall 336 is a drop in the bucket. Mean while I see 996 GT3's, 997 tt/gt3s which are way newer loose fitting more frequently. Never even seen it happen on a 996tt or 996 GT2 in the 10 years I've been tracking. With exception to the one guy on this forum who had it happen. Still though didn't personally see it during my track days.

 

this is key: "Porsche identified a manufacturing quality issue with the supplier's application of adhesive to coolant pipe fittings that resulted in elevated failure rates in approximately 6,800 early production 997 generation vehicles (MY 2007 and early MY 2008). ODI's analysis of field data showed that the age-adjusted failure rate for these vehicles was approximately six times greater than MY 2001 through 2005 996 generation vehicles and MY 2008 through 2011 997 generation vehicles built after a process improvement for adhesive application was implemented by the supplier."

... won't be losing anymore sleep worrying about the coolant lines.. but i sure hope it doesn't happen.

 

I am not convinced its 336. Once warranty is up, lot of these cars go to Indys of which don't get reported.

 

And there you have it.

 

Well I guess it won't happen to anyone else. You guys can go back to your bliss. Probably ought to start purchasing factory replacement parts, if in fact they do ever fail, as these are much better than welding or other means.

I certainly do believe that if the government says that everything is good, then it must be, they have produced excellent results in many other cases.

 

i don't think anyone is saying that findings of a government agency wouldn't demonstrate, or reflect, a "pro-corporate" bias, particularly in an increasingly fascist government, such as we now subsist within. but rather, that there simply weren't *enough* cases of failures ( or a high enough failure rate, by percentage ) to demonstrate any "liability" or "contributory negligence" by porsche, that might require some compensatory action from vag, such as a finding requiring a "preventative" retro-fit or fix of all affected cars, still in service.

certainly the findings, ( and subsequent non action ) should not come as any surprise. VAG is certainly large enough not to have been made an example of.

one might say , they are "too big to fail" LOL

 

If you read the forums, you might be led to believe that every single TT will experience this failure - not if, but when. I guess it's just another case of confirmation bias - you could be so paralyzed with fear of catastrophic failures that you might never leave your garage. Or - you might be so inclined to replace every single component before it becomes the next statistic.

I got 99 problems, but this ain't one.

 

Well said.

 

Just like the Cayenne, these coolant pipes will fail.
They will experience this problem more than they won't. It is not an isolated incident. As stated before most of the repairs gave been done after the warranty is expired. Consider yourself lucky. If these stay in place for years to come. This is simply a game of odds, the odds are in favor that the glue deteriorates, just as the Cayenne plastic coolant tubes deteriorate. Simple as that
