Guest k21xfr Posted August 14, 2012 Share Posted August 14, 2012 i have noiced as I go above 80mph the engine light comes on as soon as i come off the motorway it goes back off? cant understand this why it only comes on above a certain speed - any ideas? or does it need to go on a diagnostic? thanks Quote Link to comment Share on other sites More sharing options...
Nic Posted August 14, 2012 Share Posted August 14, 2012 Likely causes are: 1. Speed delimiter/speedo convertor 2. Auto front spoiler has been removed. Do a diagnostic check to see if there are any error codes stored, see here: http://www.mkivsupra.net/vbb/showthread.php?35920-How-To-Check-the-diagnostics-codes&highlight=error Quote Link to comment Share on other sites More sharing options...
