    Audi Q3 TDI 2013 Haldex deactivation

    Hi.
    To verify source of vibration I would need to deactivate haldex coupling. Despite information in wiring diagrams there is no fuse (no 10) present in the car that may be taken out for this purpose.
    I have found in BASIC SETTINGS of haldex : " open 4motion coupling for ignition cycle" .
    Could someone explain if this will disconnect haldex for one ignition ?
    Is there another way to deactivate it temporary without a risk of damaging?
    thank you

    Perhaps you already know this, but for clarity:

    Deactivating it doesn't disconnect it - the drive shaft from the front to the rear will still be driven by the front diff, and the rear diff and output side of the haldex will still be driven by the rear wheels, so basically the whole system will still spin as usual, it just won't have a coupling ability of when its activated.

    Unplugging the entire unit, or the oil pump will deactivate it about as good as you'll get.

    Thank you. You're right but I have a vibration on hard acceleration on 5th and 6th gear from 2000 to 2500 rpm. It looks more power is being sent to the rear then as haldex measuring blocks show increased values (amp, voltage, PWM). I'd like to verify if it's the same with power only at front.

    Is it safe to run the car with haldex unplugged? Normally with haldex 5 10% power is being constantly sent to the rear...
    Will starting basic setting "open 4motion coupling for ignition cycle" disconnect coupling? When should it be started, with the engine running or stopped? I don't have possibility to reach plugs under the car. Thanks.

    At my work we would normally remove the prop shaft and road test - also enables to have a feel of the universal joints on the shaft which we have found is often the cause
