Rear spoiler instructions for bleeding hydraulics

Recommended Posts

Hello,

I am planning to replace a leaky rear spoiler ram. I understand the bleeding process for this takes some effort. Can someone post the tech instructions?

Thanks!

Chris

I sent you a PM.

Could I also get thoes instructions? thanks

Me too, please!

One of my rams is wet and I'm getting the spoiler control failure message, even though it still seems to be fully extending and retracting at the moment. A quick look at the instructions will give me an idea of what I might be getting into. Thanks

Loren or anyone else,

does anybody have instructions on how to bleed/ adjust the hydraulic system for the 996TT rear deck spoiler? Mine is going up unevenly although I have yet to see a "spoiler failure light".

Thanks

Under what conditions?

What model year car?

Standard, or aftermarket spoiler?

2001 996 turbo, total stock car, no mods, when I hit the spoiler button or drive above 70 mph. It does not go up. I get the light.

Thanks

Most likely something as simple as a microswitch.

A PST2 or PIWIS will likely narrow the problem down.

Where are you located? Do you know an independent or a friendly dealer with a PST2 or PIWIS?

I am in Central OHIO. I guess I can try the local Porsche store, unless someone has a suggestion.

If you do not feel comfortable doing this procedure please take your car to a shop that has experience doing this.

This is straight from the factory manual.

Bleeding the spoiler pump unit

post-1-1178510134_thumb.png

1. Pulling out pump

Pull hydraulic cylinder 2 out to the dimension Y = 35 +2 mm . To do this, connect 12 V to the pump. Observe polarisation arrangement A.

2. Bleeding short hydraulic line

Slowly tighten short hydraulic line 4 until the hydraulic cylinder 2 moves. If the hydraulic cylinder has reached the lower mechanical stop inset X, push back onto the stop if necessary, hydraulic lines must be laid parallel to each other inset Z. Tighten banjo bolt 3. Tightening torque: 15 Nm (11 ftlb.)

3. Bleeding long hydraulic line

Slowly tighten long hydraulic line 5 until the hydraulic cylinder 2 moves. If the hydraulic cylinder has reached the lower mechanical stop inset X, push back onto the stop if necessary, hydraulic lines inset Z must be laid parallel to each other. Tighten banjo bolt 3. Tightening torque: 15 Nm (11 ftlb.)

Note: Use only Pentosin CHF 11 S (or it's replacement).

Where do I top up the pentosin fluid? does it do into the pump or the rams?

The hydraulic cylinder can only be filled in a retracted position.

Position the hydraulic cylinder vertically and fill with 5 ml Pentosin (per hydraulic cylinder) using a syringe.

my spoiler is in the lowered position, is there a manual way of lifting it up so that I can remove the wing and pumps? I've tried putting a 12V supply to it and I can only hear the motor running with no movement.

I also understand that there is a special tool required to remove the rear wing from the rams, is it absolutely essential that I use this tool or can I use something else to substitute.

many thanks

I have a questions with respect to a 2003 X50 I

just purchased. The spoiler appears to go up fine once the car

hits the proper speeds. It also goes up fine when the manual

buttun is depressed. It takes a while for it to come back down

automatically and also manually (it waits for something to reset).

The spoiler failure code comes up after the spoiler raises. The

bottom of each ram has a little fluid on it. The car has been in

storage for 1.5 years. Anybody help me get rid of this problem?

Have you done this procedure before, Loren? If so, how long does it take? My PS actuator is failing everytime i hit 75 or hit the button now. The wing lifts crooked. :( I was wondering if you'd be willing to take on doing this job on my car? I'd pay of course and drive the car to you. Could you let me know?

Thanks!

Jon

No, I have not personally done this job.

Those instructions are from the Porsche Service manual so they should be spot on.

thanks Loren. I guess I'd still need to buy at least one new actuator before i could do this procedure...

I gotta think if it's really worth the money and effort to get this working normally again. I love the stock turbo wing, but do I love it that much???

lol.

I'm a bit confused by the instructions in the manual for bleeding the system. The instructions in step 2 tell you to slowly tighten the banjo bolt, butt the illustration shows it being turned counter-clockwise. Are the banjo bolts left-hand thread?
