Our team of auto technicians can provide all of these answers and repairs, usually in the same visit. Since there are often no other warning signs, some owners might think it’s okay to continue driving with a check engine light alert.  That little, dark yellow light on your dashboard is an early indication of a problem that should be addressed immediately. It’s designed to give you enough time to get to Ashton Autos before any further damage is done to your vehicle.  Just ‘reading the trouble code’ is not an engine diagnostic test for the Engine light coming on.  When the light comes on, it may stay on for several days or may come on for just a few minutes and then go off, but when it's on it needs checking.
