I did the same on my 2003 S40. The light flashed and went out when i released the odo button, however, when i switched the car off and on again, it was back. Any ideas?

I recently acquired my 2003 S40 and have been playing around with the idea of modding the car, however, finding any performance parts on this car has proved to be a real pain in the behind, especially in South Africa. Does anyone know where I could find such parts (both body and engine) ?
