Some of the same engine performance problems which are indicative of an EGR valve failure can also indicate problems in other parts of the system. This can include the likes of faulty spark plugs, spark plug wires, fuel filters, fuel pump regulators or engine sensors. Some of the most common problems are detailed below:
Symptoms. There may be no symptoms of a P0404 DTC other than the MIL (malfunction indicator lamp) or check engine light. However, Exhaust Gas Recirculation systems are inherently problematic due to carbon buildup in the intake manifold, etc. This normal buildup can lodge in an EGR valve, holding it open when it should be closed.CHDriver said: Just received a letter from BMW extending my "Exhaust Gas Recirculation (EGR) Cooler" warranty to ten (10) years (from vehicle in-service date). Am pleased that BMW has done this as I will now NOT pursue EGR delete. Received notice for both of ours on Tuesday. GLFBGGY. '00 MRoadster, '14 535d xDrive, '18 X5 35d. '00 528 passed on.

In the case of the P042F, the valve appears (to the PCM) to be stuck in the closed position. The designation A applies to a particular position or stage of the step-down EGR valve control system, which is explained below. The EGR system is responsible for allowing the engine to consume a portion of the unburned fuel from the exhaust system.
