What could be the reason and solution to a sudden drop in mileage?

처리 내용

A 'sudden' drop in mileage means a component has failed, especially if it was some time after the service. The first thing to do in this sort of event is to do a leak-off test on the injectors. If an injector has failed this will show it. A faulty injector will allow a lot more fuel through, usually accompanied with black smoke from the exhaust. Second thing, or at the same time, check the electronics for correct operation and presence. Both these proceedures would be best done in a workshop. A further consideration would be the exhaust. Check for damage, or if fitted with a DPF, does it require a Re-Gen?
