Activar Parking Heater

Hola:

Segun he leido en el foro de OBDEleven que algunas personas han activado la calefacción auxiliar para el motor como Parking Heater codificando con el vag-com sin necesidad de comprar el kit de activacion wirless.

From factory this heater is used only after engine start, but its easy to make it work as a parking heater and activate timers menu in RNS.

1 In Hidden menu check option car/cardevicelist - Auxiliary Heater
2 set option Auxiliary Heater to 5 in car / carmenuoperation
3 set enabled bit 4 in byte 1 of 08-AutoHVAC module.

Then turn off the ignition and start once again. A menu Aux Heater should appear in Climate screen of RNS. There you could setup a day, time and duration of heating. at fixed time you should see ventilation start, and even some smoke under the car.

I was able to execute step 1 and 2 in "green menu" but I don't know how to execute step 3 with obdeleven, is it possible to execute step 3 in obdeleven?

Con esta activación consiguen poder programar la activación de la calefacción mediante el FIS

Me interesaría hacerlo en una seat Alhambra 2017 equipada con Webasto Thermo Top 5 EVO pero en mi modulo 08-AutoHVAC en el Byte1 bit 4 me aparece marcado el bit con la descripción "Function light dimming via light Sensor active"

¿alguien tiene información relacionada?
