After performing a short test on the vehicle, one or more faults are stored in the DME,
- 2E81
- 2E82
- 2E83
- 2E84
- 2E85
The water pump is defective or there is a malfunction with the power supply/ground circuit or no communication with the electric water pump.
Correction
Check for the correct voltages at the water pump.
- Pin 1 - 12 volts
- Pin 2 - 12 volts
- Pin 3 - approx. 8 volts
If all the voltages are correct, replace the water pump. In the case where only faults 2E81 and 2E85 are stored, perform a battery reset and check the operation of the water pump. In the event of replacing the water pump, be sure to perform the bleeding procedure.
2ef5 Bmw Codes
When replacing the water pump, the aluminum mounting bolts require replacement. Because the mounting bolts are made of aluminum they require a torque sequence that must be followed without fail. The aluminum bolts can be identified by the color blue on the head of the bolt. The aluminum bolts must always be replaced when removed because they are designed to be one-time use hardware. When installing the water pump, the aluminum bolts must be torqued to 10-15 Nm initially, then an angle torque of 90 degrees.
