Spoiler Light

Recommended Posts

I know the spoiler light illuminates when you start your car and stays lit until you start moving. When you are driving and go above 75 does the light illuminate when the spoiler deploys? Is deployment proportional above 75 or does it just go up? I have yet to see mine deploy. Can you see it from the drivers seat?

Its best to get a passenger or someone following your vehicle to check if the spoiler deploys. At 75mph, the spoiler extends fully - no proportional position. The lamp illuminates if the spoiler fails to extend fully, or retract fully.

The Dash Indicator is a Fault Indicator, not a Deployment Indicator. It registers a Fault at start-up because the ECU needs to speed calibrate itself (to insure deployment of the Spoiler at the proper speed). It cannot do this until the car has moved approx. 3MPH, so technically, until the car reaches this speed, there is a fault in the system.

The Spoiler cannot be seen from the Driver's Seat, but should it fail to deploy, you'll definitely feel it, the back end can get pretty squirrely.

The Spoiler deploys at 75MPH and retracts at 50MPH. It provides no downforce whatever. Rather, as it's name implies, it spoils the airflow travelling over the boot. If it didn't, this flow would generate lift, which is why it gets loose without it. Also, Porsche claims that the Spoiler, once deployed, also reduces Drag an additional 0.04.

Happy Motoring!... Jim'99
