@volveeta After changing parameters, you have to shut off the car and lock it long enough until all ecus are fully shut down. This can take up to 20 minutes. After that time all changes made "should" be active and in effect. For the first ERS attempt, you should drive around for a while and then leave the car locked and alone for a short period of time. If ERS is actived, but still not working, there usually are messages on the dash, which prerequisits are not okay. The car should be parked on halfway level ground, battery SOC over 80%, enough fuel in the tank, parking brake applied, no active DTCs in the ECM and TCM.
If you press any key on the fob, after the ERS is triggered, the car is immediatly shuts off.
