Did you start getting this 5DEA code after your cats and tune upgrades?
Mine did... Also, RIGHT after the front mid driveshaft was done-within a day. Not sure how that could effect anything though

So far I have tested both front wheel sensors(they tested good, also cleaned them, replaced the actuator gear(even though it was in perfect shape), replaced a perfectly good battery and registered it(a couple times), code is there with winter and summer wheels(factory setup, normal sizes normal tread)

My next to check is speed sensor values at module, power at TCase & TCase module(in trunk), check steering clock values, and something else(adaptations for steering something? Am I missing anything?

Have you or anyone found the fix to the 5DEA CODE yet?
