    Beetle MKIV 1.8T Automatic Rear Spoiler Operation

    I am trying to determine the trigger process of the factory rear spoiler.

    I am interested in the exact chain of components that automatically activate the rear spoiler.

    I have viewed the Bentley Paper and DVD service manuals, spoken with VW master techs. and VW/Audi performance techs., still I have found no definitive answers.

    Does anyone have “factual” information regarding this subject?

    I think it just listens on the CAN bus for vehicle speed messages?

    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,

    I am trying to determine the trigger process of the factory rear spoiler.

    The J223-Rear Spoiler Control module receives the 'Vehicle Speed Signal' from the J285-Instrument Cluster via the (A27) circuit, a purple/yellow wire from the T12/7 on the J223 to the T32/3 (blue/white) wire at the J285, the wire changes color after the T5c/4 connector located on the right side C-pillar.

    All this information can be found looking at the wiring diagrams for the 'Rear Spoiler'. Best to use the Official Factory Repair Information for wiring diagrams.



    Hope this helps,
