Hello, I would like to retrofit a trailer coupling on a Trafic 3 year 2019. The car has ESP with trailer stabilization. Does anyone know if the trailer stabilization has to be coded and which electric sets can be used to recognize the ESP trailer? I already asked for it at a Renault workshop, but you didn’t know it exactly. The statement was that if it is necessary, then it will probably be done. Somehow it didn’t make a competent impression. Do I actually get any message from the vehicle if the ESP has recognized the trailer and switched it to a team stabilizer? None of this is in the manual.
