Noisy auxiliary water pump
I have a whining noise coming from my electric aux water pump.
I removed the HVAC panel and cleaned the air sampling fan,
It's whistle clean now. It's not the sampler fan
No question, it's the aux pump, I can listen to it then cycle cabin fan off and on.
It's a whiny pump.
No leakage, just noise. Anyone else hear this on the mighty X5?
