My check engine light came on at the same time my S3 on the dash started blinking. Now it won't shift from 3rd to 4th on the highway and at 4000 rpms my gas mileage has dropped severely. Ive read enough and your great website to know to look at the atcu which blinks ten times. What error code am I having? Please help! Thank you.
