This AdBlue Reset should ONLY be performed after the Tank is completely Full Measuring Block Group (MVB) 174/1 should show 00000100 after resetting this Channel.
Save “001” as the new Value to reset the AdBlue level.
Note:The 2009-2010 NAR Market VW Touareg has noted issues in this particular area.If this Reset will not work,it may be necessary to remve the fuse for the AdBlue System followed by an Ignition Cycle to create a Fault Code and Re-adapting the channel.
Input new value “0001” and click “Test”
Then click “Done Go Back”
If you want to measure it,click “Meas Blocks-08”
It is 174 Group,Done to back
Now turn ignition off,then turn it on again
And well normally that engine goes off but what’s nice is AdBlue warning which was right over here telling 200 mile until it shut down is now gone.
