    Does anyone know where the relay is located for the heated seats and what relay it is.
    mine won't heat now, and I've checked the 35A fuse in the side panel fuse box which is fine, so I can only presume its a relay issue as both seats won't work.
    if anyone has other ideas please feel free to express

    Might be worth trying a request for a wiring diagram as you may find theres no relay at all, it could be all run from the bcm or whatever audi call theres?
    The 35a fuse may cover the power side, but what about the trigger side, ie the power signal from the switch to the bcm/relay etc?
    Have to say 35amp is a bloody big fuse for heated seats, thing the ones in my old landy are 10 amp. for both seats.

    The seats are turned on from the heating control panel via rollers (potentiometers)
    The strange thing is both seats have stopped working and the passenger seat is rarely used!!!
