Automatic Spoiler Question

Recommended Posts

Does anyone know if the spoiler on the back of a 2001 Carrera 4 (996) goes up automatically at a certain speed? I can bring it up manually using the button near the clutch pedal but I don't think it is coming up automatically when I am moving along at highway speeds. If anyone knows what to check if this is not functioning as intended, please help with some things to check for or ways to test it out. Thanks!

Shouldcome up at 74 mph. Open the rear engine bay, to the right of the engine just behind the rear light cluster in the engine bay itself you will see a connector that should be attached to a clip. Unlcip it and disconnect the conector, reconnect it and repeat a few times. This should fix it.

Muck gets in the connector and meses with the circuit.

I have an '02 C4 Cabrio that I'm just as suspicious of. The spoiler works manually but I had my wife look back at 80mph and she didn't see it. I never got the warning light.

1) If the connector that Scouser mentioned was intermittent or faulty, would the spoiler also not work manually?

2) Is it possible for the spoiler to be down at over 80mph and not initiate a warning light? Is this warning triggered by hard limit switches that actually detect the spoiler's position or is it possible for them to be fooled in a case where the actuators are not being energized?

when I start the car - I get a red spolier warning light on the dash until I pull off, when it goes out. I never see that warning light again until I re-start - prehaps if you dont get a warning light on startup (which I have been told is normal) the bulb has been removed or there is a fault with it.

Btw there's no way to see the spolier from inside the car unless you pull alongside a very clean and shiny truck or car on the motorway - which I did the other day just to check!

When I first got the car, I asked my wife to follow me on the m'way one day and she said she "could not see anything"....so I asked a mate to do the same thing and he confrimed it was working as it should, lifting at speed and lowering when going slow....turns out SWMBO had misunderstood the "brief" and was lookign for soemthign completely different- cant imagine what though...

a-bart, I'm with ya on the spouse thing. The light however does cycle on startup. I was asking more about can it not signal when above 80mph and spoiler is not actually extended (although perhaps has gotten the electronic signal to do so).

there is a spolier indicator that you can wire up to one of the blank switches on the dash - they're on flea-bay from a guy in Germany for not too many $$$$s...but Im not sure how it actually works - Ive looked into it though - its a doddle to fix up though
