    Yes, thank you for your answers. My question is more like, does the bulb error come on when pressing the brake, starting the indicator, directly when key is turned, etc?

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Hello Iichel

    does the bulb error come on when pressing the brake, starting the indicator, directly when key is turned, etc?

    Borja: Yes the Bulb error come when presing the brake, activate the turn right/left indicator , When the key is turned on nothing happens until i activate any function of the lights

    Hello Ounus


    I want to confirm if the information sharing with you regarding Byte 18 are the correct one:

    Steps:

    1.-I go to the "Select control module" option from the main screen
    2.- Then I select "09-cent. Elect. " Button
    3.- Then Coding "07 button" and a menu pop out with several options i select the one on blue, I dont know if the other ones are different options

    4.- From the option on blue selected on the previews step i go to the 18 byte as you can check the value on the image

    Thanks

    I'm afraid this cannot be solved, the PQ25 BCM that you have in your jetta has no option to disable the warning light for indicators (i.e. if you install LED).
    The warning light for the brakes can be disabled if you set the byte for the light diagnosis in the BCM.
    I guess the LED tail lights has only been an option for the PQ35 BCM.

    Just to verify, all of the lights in the rear LED cluster work?

    Sounds like your best option is to add resistors in parallel with the indicator LEDs - this is what I had to do on my other car (a Citroen C1) to make them flash at the correct rate.

    Yes, I agree, but I wouldn't call it a nice solution for an OEM installation.
