    Newbie question regarding adaption

    Hi there!
    As a last resort, Im now playing the sad violin and creating a thread regarding my issue.
    My headlight washers is not working on a car I recently bought, so I thought I would make them work again.
    First I tried the output test, and the V11 headlight washerpump is working like a charm.
    Then I checked central electrics if the adaption was correct, and it was not.
    It was set to 114, god knows why.
    Channel 013: Wiper Setup
    Standard: 115
    +001 = Speed Reset
    +002 = Short to Plus Monitoring
    +004 = Rain Sensor active
    +008 = Long Post Wiping after Washing (Drop/Tear Wiping)
    +016 = Speed dependent Wiper interval active
    +032 = Headlight Washer System active
    +064 = Reverse Gear Wiping active
    And here comes my newbie question, since I have been on google for the last 45mins without a relevant thread

    To activate the headlight washer system, is the new value:
    115 + 32 aka 147 or
    115 + 1 + 2 + 4 + 8 + 16 + 32 aka 178 ?


    i have tried them both, and neither of them is activating the headlight washerpump.

    I dont have a full scan, dont think it will be necessary for this question.

    114 = 2 + 16 + 32 + 64. So "+032 = Headlight Washer System active" is already active.

    Changing it to 115 would add "Speed Reset". I'm not sure exactly what that is.

    178 = 2 + 16 +32 + 128. So that wold drop +064 = Reverse Gear Wiping active, and it would add 128, which is undefined.

    Thanks for the reply.
    Unfortunately none of the values you replied with works.
    Something else is fishy here, since the pump is working with the output test..
    I currently have my front bumper removed, will the control module prevent the headlight washerpump from engaging due to the missing fog lights?
    I know that it wont work with dipped headlights etc.
