The P2293 code means:

👉 The fuel pressure regulator system is not maintaining correct pressure

Modern engines—especially direct injection (GDI/FSI/TFSI)—require extremely precise fuel pressure.

The P0463 code means:

👉 The ECU detects a HIGH voltage signal from the fuel level sensor “A”

The P2068 code indicates:

👉 Fuel Level Sensor “B” Circuit High Input

In simple terms:

• The ECU receives a higher-than-expected voltage signal

• From the fuel level sensor (usually the secondary sensor in the tank)

The P2015 code means:

👉 The intake manifold runner position sensor signal is out of range or incorrect

This sensor tells the ECU where the intake flaps are positioned.

The P2006 code means:

👉 The intake manifold runner control (IMRC) flaps are stuck CLOSED

These flaps regulate airflow inside the intake manifold.

The P2004 code means:

👉 The intake manifold runner control (IMRC) system is stuck open

Inside the intake manifold, there are flaps (runners) that control airflow.

The BMW 29E1 code indicates a fuel mixture control problem on Bank 2.

The BMW 2A2C code is a mixture-control fault for bank 2. In BMW-specific fault lists and forum diagnostics, 2A2C is repeatedly associated with fuel mixture control on bank 2, and depending on DME variant and companion codes it can point to a condition that is effectively too lean or too rich rather than naming one failed part by itself.

The BMW 2E85 code is most commonly tied to a BSD bus communication fault involving the electric coolant pump. In many BMW diagnostic reports, 2E85 appears as a “BSD, message; electric coolant pump: missing” or similar wording, which means the DME is not receiving the expected communication from the pump over the BSD line.

BMW fault code 2F4A usually points to an EWS/CAS-to-DME interface problem. In practical terms, the engine computer and the immobilizer/start authorization system are not communicating correctly or are not agreeing on authorization data. BMW code lists commonly describe 2F4A as “Interface EWS-DME electronic vehicle immobilization / digital motor electronics.”
