From what you described, sounds like it could be the speed converter that's at fault. Usually a ropey box to convert kph to mph on your speedo. It's a common problem.

 

Can't exactly remember the conditions under which it does a check, but it's something like water temperature over a certain amount AND rpm over 3000 for a few seconds, then if the speed signal is not as expected it will light the warning lamp.

 

It's code 42 when you do the ECU diagnostics check.

When you switch on your ignition before you start the car do all your warning lights on the top right hand side light up? If not there could be an engine management light on (its a common fault for dry joints on the box to allow the engine management light to not light up) Is it an auto or manual. If its an auto and you have speed limiter faults they also show with an O/D off flashing light (and correct me if I'm wrong a flashing trac control light?) Also I think if its the lip spoiler causing the fault does not that light in the switch flash as well? Mine has an FMIC and that kept my warning triangle on.

 

Do a search on flashing O/D that will turn up alot of reasons why that light comes on http://www.mkivsupra.net/vbb/showthread.php?t=44475&highlight=flashing+o%2Fd is a good one to start with

I see some gaps in the lighting dials, anything else that should light up?

 

anyway, went for another spin yesterday, didnt go anywhere near redline, just over 70 leptons and light on again?
