So - what potentially is wrong with my car is either...
Ad blue injector,
Ad blue heater (less likely),
NOx injector,
Tank sensor,
Ad blue catalyst...
All of these are about £20 using the code MID60 on eurocarparts right?
Its unlikely to be the heater or tank level sensor given the code you have
So the system doesn’t work properly when it’s being used for short journeys, or longer stop/start journeys, it’ll only work on say a motorway or dual carriageway at constant speed for a prolonged period? And it definitely doesn’t work if it’s been horsed on?
It’s not that it doesn’t work on short journeys, it’s that it isn’t designed to operate until certain temps are reached
It will operate on all other journey types however I advised the best drive cycle to allow the efficiency monitor to run - steady state cruising is best for this
