Why AdBlue faults need attention quickly
Many AdBlue systems start a mileage countdown when the SCR system detects a serious fault. Once the countdown reaches zero, some vehicles will not restart until the fault is resolved.
Common AdBlue and SCR faults
NOx sensors, AdBlue pumps, injector faults, heater faults, wiring issues, crystallisation and ECU communication problems can all create warnings. The same dashboard message can have several different causes.
Clear repair advice
We check the fault codes, live data and system behaviour before recommending a route. The answer might be a sensor, pump, injector, wiring repair, software update or further SCR testing.
