Concern

MDEG/HDEP Euro VI standard NOx sensor monitoring inoperative

Defect, as DVSA words it

The EU directive for commercial vehicles with the Euro 6 emissions standard stipulates that the NOx sensor signal is regularly checked for plausibility. The IUPR monitor (In Use Performance Ratio) was defined for this purpose. At a minimum 50% of vehicles in a class must have this monitor be active at least 10% of the possible time. This is not the case for the affected vehicles. Cause Parameter error in data record creation.

Remedy, as DVSA words it

To remedy this an update software version in engine management (MCM) and exhaust gas aftertreatment (ACM) control units is required.

What changed since we first read it

Nothing yet. The wording has been the same on every read since 4 September 2026. The file is read again every day; if DVSA rewrites the defect, remedy or concern, the old and new text will appear here with both dates.

The same recall in other registers

No match found in the American, Canadian or European registers by manufacturer reference. A recall can exist abroad under a different reference; this site only claims a match when the reference agrees.
