+1. Porsche should have just gone with the GT2 wing for the turbo, and been done with it.

Same symptoms - Spoiler doesn't goes up
I don't know if this happened after a leak or concurrently with a leak.
I followed a collection of posts attempting to bleed and add stop leak, all of which failed. On a test bench with 12V battery, the rams didn't move at all.
I gave up and ordered the fixed wing kit, but since I had all of this kit in hand I decided to take it apart and see what seals are present, how it works, etc.
Much to my dismay I found that there's a large plastic block that's threaded.
The motor turns a threaded rod which moves the plastic block up and down to push the hydraulic pistons up/down in their cylinders.
Upon disassembly I found my plastic block broken into two large pieces with a few smaller sharp shards.
So, the failure is first the broken pump, then possibly a leak and/or problems with lift cylinders.
For $150 I'm making my wing a fixed wing. Screw you Porsche.

It is a bad design which is why I went with fixed. Hate leaks.
Great idea from OP...thanks for sharing this. To late in my case.

My sentiments exactly! It's a stupid articulating spoiler to begin with.
What harm would there be in designing and selling a simple fixed wing?
Who needs or wants a silly up/down toy spoiler?
On top of that, they make one that leaks, needing repairs costing thousands.
I'm in the process of bleeding mine now and particularly frustrated by the inconvenience.

like many things on these cars it is a personal preference.
I had a fully functioning rear wing. I removed it and installed the fixed wing. I just prefer the looks of the wing up all the time.

Help Please!
OK, following your directions, I mistakenly disconnected the leads to the pump (step 3) before raising the wing after unbolting the hydraulic lines 
. I reconnected the leads but the wing does not move. I get the error message when I try to activate it. Checked the fuse and it's ok. Any suggestions?

OK, so after my post I realized the wing is obviously not going to move with the hydraulic lines disconnected. However, there is no noise or movement coming from the pump. It jerks slightly as if it's getting power when I initially push the switch, but nothing happens. I can insert a screwdriver about one inch into the holes. Any other suggestions??

Just to verify the pump works or not, connect power using jumpers from the jump start terminals over the motor. This is direct 12V essentially from a power source, not from a harness, through switches, relays, fuses, etc. Momentarily connect it and it should work, either polarity.
It does sound like your pump is bound up, broken parts around the ram.

OK, got the pump to move with a bench test battery, so I guess I will deal with the broken switch or relay after re-install. Now, however, I am wondering how much fluid the rams will suck out of the bottle? I used the method in step 5, and pumped about 10 times on each side of the wing, but the fluid level in the bottle did not seem to change. Will there be a noticeable amount being sucked up??? I used Lucas and Pentosin, but that seems like it shouldn't make a difference.
