    Hi,

    I've got a strange problem which i can't work out whats going on. I've got a B7 Passat Alltrack and I get the long beep and the flashing button when the park assist turns on. I've got an OBDEleven and doing a scan i get a "supply voltage for park assist sensor. Voltage too low" error. The sensors dont normally work (fingernail test confirms this) but when i disconnect either the front or rear sensors from the parking module they do work (I can feel them on my fingernail). But not if both front and rear sensors are plugged into the parking module. The voltage measured by my OBDEleven is 12.3V for 'Voltage Terminal 15' and 10.3V for 'Supply Voltage for park assist sensor'.

    I also just replaced my battery today as i though maybe that was the issue. But its not.

    Any ideas would be appreciated.

    Paul

    Hi Paul, did you found the problem? I have exactly the same problem, I´m unsure if it is some parking sensor that cause the low voltage problem or if it is the parking module.
    Did you change parking module and everything started to work or was it some faulty sensor?

    thank you.
    Regards Antono

    I have a problem with my parking sensor ( VW Passat B7 2011 )

    1079828 - Supply Voltage for Parking Aid Sensor(s)
    B107A 14 [009] - Open or Short to Ground
    Confirmed - Tested Since Memory Clear
    Freeze Frame:
    Fault Status: 00000001
    Fault Priority: 3
    Fault Frequency: 1
    Reset counter: 115
    Mileage: 251095 km
    Date: 2090.14.29
    Time: 19:01:03


    I accessed the AID module. First, I unplugged the first 12-pin plug from the left (Back sensors). After clearing the errors:


    1079828 - Supply Voltage for Parking Aid Sensor(s)
    B107A 14 [009] - Open or Short to Ground
    Confirmed - Tested Since Memory Clear
    Freeze Frame:

    Reset counter: 115
    Mileage: 251101 km
    Date: 2090.14.30
    Time: 17:54:19

    I can comfirm that all front sensor work, used telephone microphone to confirm "pulse-noise" from sensors and able to see distance-values from VCDS diagnostics.


    Then I plugged the plug back in and unplugged the second 12 pin (the middle one - front sensors). I cleared the errors and this time two appeared

    I can comfirm that all back sensor work, used telephone microphone to confirm "pulse-noise" from sensor.


    I´m unsure if problem with the module unit (3AE 919 475) or maybe some problem with sensors but unable to find sensor fault when everything seems to work
    Or maybe some connector? My feeling seems to be parking aid unit but unsure

    Regards
    Antonio
