Front (air) suspension cracking sound over speed bumps

[Bennie]

Thanks byebye! I had the same noise in my car when driving over bumps. During the test ride (in bad weather conditions and -1 degrees C temperature) we couldn’t hear it

The dealer examined the bottom of the car but couldn’t find anything. I just sended them the bulletin, because the complaint was new for them.

OK, so my dealer looked at this bulletin and consulted Porsche. At first they responded this issue is specific to US market and does not apply to EU. However they have another demo car with this exact problem and it seems there are more cases. They will apply the fix to their car first to see if this is the case and I'm going back next month.

@Bennie can confirm this is weather based, it's very possible this issue is less annoying in cold temps as metals shrinks. I hear it way less now.

Anyway - if you have this issue as well, go escalate so they know it's not isolated. How to reproduce? Use brakes on speed bumps, which makes it more obvious.

I've noticed some "clunking" type sound from the front end when lightly riding brakes over speed bumps.

The TSB posted looks easy enough to inspect myself... it's all top side under the trim panels in the frunk area it looks like.

Although it looks like the fasteners are torque to yield type... ugh. so don't touch them

Thanks, I'll ask. They claim the other demo cars behaves the same way. This noise is only present when applying brakes over bumps. I'll try to record a video after picking up the car.

Yikes, I know that sensation from other problematic air suspensions I've had.... when gently braking over uneven terrain like a speed bump, and the shock compresses a little, there is some slop or knock in that corner (or end) of the car. It always feels like loose lug nuts and the wheel is insecure - even tho that's not the issue. Sloppy knock, not a solid thump like you'd expect.

Gonna be watching this thread!
