P2713: Electronic pressure-control valve 4 in the BMW transmission

The BMW GS chart associates 4E23/P2713 with electronic pressure-control valve 4, corresponding to pressure-control solenoid D. The fault is registered according to the control-signal status. The source does not describe it as a direct measurement of hydraulic pressure or provide a pressure threshold.

Electrical command evidence comes first

The monitor is enabled with ignition on and voltage between 7 and 16 V. A time- or event-controlled filter counter determines memory entry. These facts establish the monitored control context, but they do not identify a particular internal hydraulic leak or demonstrate that the transmission requires a complete overhaul.

BMW's service decision depends on the error-frequency counter. More than two occurrences leads to mechatronic replacement in the chart. A passive entry receives a different path: memory clearing followed by a monitored road test, with replacement if the fault is repeatedly registered.

Preserve the information that changes the decision

Record the fault's present/passive state and occurrence count before clearing it. An erase that removes the evidence needed for this distinction makes the chart harder to apply accurately.

The record lists a mechanical emergency default mode and gearshift-specific warning messages. A technician should assess the vehicle's actual shift behavior and transmission configuration before a verification drive. The source's engine/model breadcrumb is not a substitute for identifying the installed gearbox.

A successful repair should resolve the repeated control-signal fault under the applicable conditions. The chart supplies neither a solenoid resistance value nor a connector test, so those must come from the exact transmission's detailed repair information.
