Dosing valve testing results and NOx sensor actual values.

NOTE: This is an update from the November 2015 webcast.

Remember when performing the SCR dosing valve test ensure the SCR control unit has the latest software version installed otherwise the test results may be incorrect. Only with Xentry 09/2015 and the latest SCR control unit SW installed, the dosing test quantity has increased to 30 grams.
As an update to the previously covered topic of the NOx sensor actual values for the operational status, the issue has been resolved with 09/2015 software with the 5153 add-on installed.
