Welcome to the forum. Sorry your having issues.
Although I do have a 2006 elise, i dont have traction control so I am not going to be a lot of help.
You say the light happens when you are going into first gear. Can I get more info?
Is this when you are going into first from a stop or when down shifting from second to first.
dumbest questions are the ones you dont ask.....
Is this a smooth shift into first or are there lots of rpm and a quick clutch engagement involve (long way to ask if its possible the rear tires have lost traction while going into first).
the more information you give, the better answers you will get.
On the big picture, you are going to love the car.
Apexes are a lot like relationships. So tough to get right, so easy to see where they went wrong.
The secret to a long life is ------- not dying.
