P2601 on BMW

Coolant Pump "A" Control Circuit Range/Performance

Moderate1 BMW model affected$500-$1,200 typical repairSystem: Powertrain

P2601 on BMW vehicles indicates coolant pump "a" control circuit range/performance. Au7o has documented this code across 1 BMW model — most commonly on X5. The PCM detects that the coolant pump 'A' control circuit is electrically intact but the pump is not responding as expected — the measured behavior is out of the normal operating range (e.g., commanded flow/voltage doesn't produce the expected result). This points to a marginal/degraded pump or circuit rather than a hard open or short. Typical repair costs on BMW range from $500 to $1,200, depending on the specific model and root cause.

Common Causes of P2601

  • •Worn or seizing electric coolant pump
  • •High resistance in the pump wiring or connectors
  • •Restricted coolant flow / air-bound cooling system
  • •Intermittent pump or relay operation
  • •PCM control-circuit performance fault

P2601 on BMW by Model

BMW X5(1 issue)

  • E70 xDrive35i N55 Electric Coolant Pump (Fault-Confirmed)2011-2013

    The 2011-2013 E70 X5 xDrive35i uses an electronically controlled N55 engine-coolant pump. A temperature warning, reduced-power message, fan running at high speed, or cooling-system fault can involve the pump, but low coolant, a leak, wiring or ground, power supply, thermostat, temperature sensing, trapped air, or another cooling fault can produce overlapping symptoms. Current BMW pump 11-51-5-A05-704 is cataloged for the N55 E70 application; it is not the common pump for the N52 xDrive30i, N63 xDrive50i, or every F15 X5, and the thermostat is a separate VIN-selected component.

Frequently Asked Questions

What does P2601 mean on BMW?▼

P2601 stands for "Coolant Pump "A" Control Circuit Range/Performance." The PCM detects that the coolant pump 'A' control circuit is electrically intact but the pump is not responding as expected — the measured behavior is out of the normal operating range (e.g., commanded flow/voltage doesn't produce the expected result). This points to a marginal/degraded pump or circuit rather than a hard open or short. On BMW specifically, this code is documented across 1 model.

What causes P2601 on BMW vehicles?▼

Common causes on BMW: Worn or seizing electric coolant pump, High resistance in the pump wiring or connectors, Restricted coolant flow / air-bound cooling system, Intermittent pump or relay operation, PCM control-circuit performance fault. Specific causes vary by model and year — see the per-model sections below.

How much does it cost to fix P2601 on a BMW?▼

Repair costs on BMW range from $500 to $1,200, depending on the specific model and root cause.

Which BMW models have P2601 documented?▼

Au7o has documented P2601 on 1 BMW model: X5.
