Well the dreaded light on the dash came on again. I'm talking about the Check Engine light. Of course I took it in and handed over $165.81. I used to think this was a random thing but now I think I know what's going on. The mechanics computer has a direct link to the manufactures computer which has a direct link to your cars computer. The mechanics boat payment is due so his computer tells the manufactures computer and that computer tells your cars computer and BLINK the check engine light goes on.
