Did you unplug the ECU's yet and see if EPC light goes out in cluster?

Are you going to configure VCDS with your own WSC. tester # and importer # and then login + recode the modules to default them yet?

Just attempted to recode both ecu 1 and 2, no difference. EPC light remains.

Also, these ECUs do not need a login for recode and if they did, I would need a security access key.

EPC light should not come on when ecu's are unplugged.

here is how the light is functioning. The first section is with the ecus plugged in and the second is with them unplugged.
