2004 coupe, 30k miles ...runs perfect.......drove 50 miles to friend.....no issues whatsoever......On my way back home , the esp/bas light came on. ....after a few miles, I pulled over and did the steering lock to lock drill,
Shut it off, restarted and headed out again......with in 1/ 2 mile, light came back on again. When I got back home , I did the steering deal again.....light went out....pulled into the garage and let it idle.....within a minute , light came back on. Shut in down and plugged in my NEXPEAK NX501 reader.....no active or stored codes........The brake light switch and the "yaw" sensor have been mentioned a possible causes.
Where do you start ? what has been the most common culprit ? p/n's..? source ? When I bought the car from original owner at 24k miles, I did a complete brake upgrade with new cross drilled /slotted rotors, pads, and wear sensors. All new Continental Extreme tires. Car is perfect, garaged all winter . It's a great car.......very uncommon in my area. I don't mind replacing parts if needed......but not on a trial and error process. Any help appreciated.
