As we've noticed in the past, the PASM cars don't have the "clunk" but any car with the black fabric skirt installed may experience rattle against the aluminum strip.

Also, make sure your rear tires are inflated to proper pressures; mine came from the dealer a bit overinflated; running them at recommended stock cold pressure will alleviate some rear harshness if your tires are above recommended pressure.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

I am a new forum member as I just bought my
Cayman
on Monday. I am totally loving the driving experience as the handling is just amazing. I do have one problem however. When ever I go over a tar strip on the higway on any other heavy bump, the rear hatch bangs and even the glass rattles. I believe there have been some earlier discussions regarding new buffers from the factory for the hatch. Does anyone know the details and are their any recommended 'self' fixes to try. This is driving me crazy and taking away from the overall enjoyment with this great car. Thank you.
There is one self help fix in the Articles section (Misc category) and lots of posts on hatch thunk, and the one you already found on the hatch spacer replacement that your dealer can do. You should have your dealer look at it.
My car was at the dealership yesterday to fix the "clunk". They didn't.
It might even be worse now. Maybe not. Their solution was to screw in the "stoppers" (not sure what they are called) thus making them shorter and the fit tighter.
The article on fixing the clunk is
great
but I'm not sure that I could pull that off. I'll probably just live with it for now.
Years ago I had a 924. It had the same clunk. I guess nothing has changed.
I wouldn't doubt th it is worse now with shorter stoppers. Making them shrter allows the hatch to move more... enouraging the clunk with smaller bumps.
From what I understand, you want to screw the stoppers (the ones with the springs around the thread at the back corners of the hatch) as far
out
as you can, this makes the hatch tighter (as described above). My dealer set them that way when the car was delivered, and along with the PASM, my car doesn't have the clunk.

I would recommend doing the "fix" per the articles section. Takes less than an hour, and relieves much of the cabin-resounding "clunk"
Also, make sure your rear tires are inflated to proper pressures; mine came from the dealer a bit overinflated; running them at recommended stock cold pressure will alleviate some rear harshness if your tires are above recommended pressure.
I am very pleased to report that my car hasn't made a single clunk and I have driven over some very rough pavement (cobble stones, sharp edges, etc...).
I have PASM, but once, while on cobble stones, I activated the Sport mode, just to see how bad it would get, and still no clunk.
(green with envy) and we ALL know WHERE he was when he was driving over cobble stone! Great to have you back, Mike.
As we've noticed in the past, the PASM cars don't have the "clunk" but any car with the black fabric skirt installed may experience rattle against the aluminum strip.

My dealer didn't know what to do either so they put in a technical request to Porsche. This is what the dealer said Porsche said: "...was informed the weight in the rear deck lid can cause this and are having us order a part to insulate the weight in the rear hatch". He didn't say what kind of part. It is supposed to be at the dealership tomorrow for installation. I'll let you know if it helped me.
Got the car back today and the clunk is completely gone. The tech I spoke to said that Porsche had them order a lighter weight for the hatch but the work order says that they removed the damper assembly and insulated it. Either way, whatever they did solved it.
This is a source reference. Confirm exact model applicability in the original material.
