I have a similar issues with warning lights. I've been searching the forum but have not found any posts with the conditions I'm experiencing.
I have an 05 Base Roadster, 6 speed.
My BAS ESP light is illuminated, along with the ABS and BRAKE lights on the far right. On the far left side, the Check Engine and Brake Wear Indicator lights are illuminated. The speedometer has stopped functioning. The spoiler light is blinking, and the spoiler remains deployed. Other than those few items, everything else seems to functioning correctly.
