    Audi B6 Seat heater scan?

    I have a 2005 Audi S4 - B6 and the drivers seat heater doesn't seem to be working. Fuse is OK and the passenger seat is working fine. Is it possible to scan for drivers seat codes w/ VCDS? How to?

    Have you checked for fault codes?

    I think seat-heating data is in MVB's 020 (driver) and 021 (passenger) of the HVAC module in that car. Compare values for the two sides. Move both heater control switches (one at a time) while observing the values.

    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.
