2008 528i overheat issue

Car started to overheat with my 2008 528i. I replaced the water pump and Thermostat - thought it's time after 4 years. After installing new pump, the bleeding process would not start. Checked fuses in the glove box (F23 30A was burnt). Replaced the fuse, new pump, new Thermostat still no bleeding noise.

Checked all the fuses in the Trunk and in the glove box but still no Bleeding or sound of the pump. are there a Relay somewhere?

Thank you for your help in advance

Keep trying... It is my experience that sometimes the bleeding procedure does not kick in...

The red wire will be hot at all times, the orange wire will be hot only when the dme relay is energized, the brown wire is ground and the violet wire is the command wire from the dme. How are you trying to run the bleed procedure?

turning on without starting
turned heater on all the way - fan low
press the Accelerator down for 10 sec
the pump should sound moving water.

I have done it before. not sure what went wrong.

By the way i noticed the heater was not working when overheated and i tried to turn the heat and AC shut. not sure if there is correlation with that.

Thanks

Did you have the hvac system on automatic? You mentioned heater not working, does that mean it was not blowing hot air or does that mean that no air of any temperature was being blown?

When the car was overheating i tried to turn the heater up to get some of the heat out. Blowing air but not hot. Since the installation of the pump and thermostat have i have not gotten the car hot enough to check.
My point is in order to bleed the system you have to turn on the heater if the heater is not working then the system may not start the bleed process.
I am 100% sure the istallalation was correct. So there may be a relation between heater not turning on and bleeing process.

The lack of heat coming out of the vents could have been due to the water pump not circulating coolant to the auxiliary water pump which wouldn't surprise me at all. Do you have INPA or ISTA or something you can scan the whole car with?

I have Delphi and Foxwell NT510 that served me well over the years. but they don't pin point terminals. INPA i found it very difficult to install with Serial port. i don't a any laptop now a days has a serial port

In addition to your bleed procedure listed above, try setting your seat heater on max before pressing the accelerator.

Problem Found

Folks, I finally found my real problem. It's the Pump harness. Somehow the harness was loose probably from last AC work. Harness was touching the exhaust and melted. Pump worked after cleaning up little. Now we have to repair the harness.

Just wanted to share with the group here. Check your harness to make sure.
