Noticed my spoiler stuck open this morning. It closed manually via the button but made some pretty good groaning noises.

I found this thread, but didn't want to go all out yet.

So I just took some spray dry lubricant and generously applied it to the following two areas.

In the first picture the black "tube" slides up and down. Soaked that generously and moved it up and down manually via the button, repeated 3 times.

In the second picture the silver metal piece slides I believe and I did the same, generously lubricated it and moved it up and down manually via the button.

Groans are gone. We will see if they come back over time.

You wouldn't know if your spoiler is groaning unless you try to operate it manually via the button with the engine off.

What spray did you use? I need to buy some

G.I.G.

My PPI uncovered a noisy spoiler so it was one of the first things I did with my car after changing the oil. I applied it everywhere @Astraelraen applied it with the addition of a small spray in the small port you see in the second pic.

I used Blaster Silicone Lubricant with Teflon. Although the dry lube might be a better choice.

Blaster Silicone Lube

I had to lube it several times while also cycling the spoiler up and down manually over the course of a couple weeks to notice the improvement.

Plastic on plastic will almost always induce friction, so I think this is something that you'll need to do regularly to keep the noise at bay. As mentioned, you can't hear it when you're driving, so I'm not too worried about it. I just don't want the parts to fail or the motor to burn out because the spoiler couldn't deploy smoothly because of increased friction.

+1 for the spoiler rebuild - one of the first things I did with my '05 997 is do the complete disassembly, clean old grease, etc. and reassembly. Took me two nights for the whole job...took my time, probably about five hours all in.

Lubricating the posts is a good start, but the disassembly gives you access to the plastic guide rails and gears. These will have 15+ y/o grease in them that is crusty, old and not doing much.

Spray some silicone spray here too

Having someone else lubricant your spoiler makes it go up and down much easier as opposed to doing it you’re..,

Groaning gone.
I had the same problem when I got my car nearly two years ago. Solved it pronto with silicon spray, which is colorless.

I did the same thing when I bought my car 18 months ago and it has not had an issue since.

Thank you, I did this and no more groaning.
