Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

had my 996 for 15 months now, recently when stuck in traffic i decided to take advantage of the sun, so i opened my sun roof, all very nice, until the traffic moved, at around 35/40 mph the cabin was filled with a booming noise, so the sun roof was closed !

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.

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

had my 996 for 15 months now, recently when stuck in traffic i decided to take advantage of the sun, so i opened my sun roof, all very nice, until the traffic moved, at around 35/40 mph the cabin was filled with a booming noise, so the sun roof was closed !

Thats how we used to solve the buffering from the sunroof. garyw

POST 5Original post

I've also found that closing the roof slightly makes a huge difference on my 2004 C2. When you open the roof on mine, there is a fully open position - which is horrendous for booming & reverberating noises - and an intermediate (approx three quarters open) position - which is fine (windows open or closed). Also - Have you checked if the spring loaded "spoiler" at the front of the sunroof is lifting as it should when the roof opens ? I found that holding it down (simulating a "stuck" closed position) increased noise levels significantly. Hope you get it sorted, Paul 2004 911 C2 Anniversary

POST 6Original post

This has happened to me on Porsche and other makes of cars. As Richard suggested, opening the window slightly seems to solve the problem.
