i got the upgraded porsche part 92857457304 ( which replaced 92857457303) and paid $900 to have it replaced and the coolant system vacuum filled.

Suggestion

I'd still replace the valve to a factory unit again and reinforce the two plastic sides with some epoxy, just to be sure.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

So this part failed for me last april, and dumped all my coolant all over the road. i got the upgraded porsche part 92857457304 ( which replaced 92857457303) and paid $900 to have it replaced and the coolant system vacuum filled. this lasted 14 months and split in the same exact spot, where the 2 plastic sides meet is there any other solution than this crappy design? i don't really fancy replacing this every year considering using a copper pipe and bypassing this valve and just having the tiptronic gearbox be cooled all the time. if this badly glued part is the best porsche can offer, then i will need to think outside the box thoughts?

POST 2Original post

I think overcooling the transmission may reduce its lifetime and probably it will take longer for it to warm up. I sold my Tip last year, but I remember the shifting became significantly smoother after it warmed up properly, and this warm-up period may last longer if you just bypass it. On the other hand, many neglected Boxsters are running out there with leaky vacuum lines, and they survive, so it's not a critical part. I'd still replace the valve to a factory unit again and reinforce the two plastic sides with some epoxy, just to be sure. My tip never had an issue with this valve, I don't know how common this kind of failure is, but I would check if the hoses and the valve itself are routed properly, perhaps there's some excessive vibration that cracks it eventually. Just my two cents...
