    2014 Seat Alhambra NOx issue

    Hi I have this Seat in which keeps coming up with NOx Catalyst efficiency below threshold.
    We have fitted a genuine NOx sensor.

    It also had an issue with adblue tank, always saying ad blue low, but after calibrating the tank that fault has not come back.
    It there a way to also check the adblue injector via VCDS?

    Autoscan attached below

    Hello,

    It there a way to also check the adblue injector via VCDS?
    There is a way to test the N474-Reducing Agent Injector. The steps below should work for this vehicle:

    AdBlue - Testing the N474-Reducing Agent Injector
    1)
    Check Measuring Values: [Long-term adaptation of reduction agent dosage]
    1.00 = Baseline (center) Range = 0.90 to 1.10

    2)
    To run the N474 output quantity test..

    Prerequisites:
    - Battery maintainer connected
    - Key on Engine off
    - No ECM fault codes, clear codes
    - Transmission in Park

    3)
    Select [Adaptation]
    Select [Adaptation for metering quantity measurement]
    Normal read value = [04]
    - Change to [02] , [Save] This enables the Basic Settings, a key cycle will reset this to a value of [04]

    4)
    Select [Basic Settings]
    Select [SCR metering quantity test] [Go!]
    [On/Off/Next]

    This BS test will run for about 10 minutes (or more), during this time the N474 will 'slowly' release AdBlue, (spec=25 to 30ml).


    Let us know how this works and also what value you had in the Measuring Values: [Long-term adaptation of reduction agent dosage].

    drpeter

    ps...... The test above works with many Audi and Volkswagen vehicles.

    Thank you will carry out the above test.

    In the mean time I tried running a test on the SCR pump, when activated its only a trickle of adblue flowing out of the pipe is that normal or should it be a steady flow?

    Hi, well..... that sounds normal, because in '10 minutes (or more) and you only get about 25 to 30ml'

    Thanks for asking,

    This test must be run with AdBlue injector removed from exhaust line and measuring container attached. Check also nozzle is not contaminated with soot.
    System leak test should be useful, too. And real AbBlue pressure check with mechanical pressure gauge.
