Electric water pump failures
I was surprised by the amount of noise coming from the water pump when speeding up and slowing down during the 12 minute automatic bleeding process. It sounded like the screetchy noise a worn out bearing would produce. Before the coolant change I read many posts about it and seem to remember that some people wanted to know, how they could tell the pump was working at all, because they could not hear anything.
There is no CEL. INPA also shows no faults.

... of course I'm being sarcastic and somewhat discouraged (for you) about a failure that indicates to me (?what do I know?) an under-engineered and over-priced component.BTW, I've never personally had a water (coolant) pump failure on any BMW (YET!). Hope I'm not jinxing myself

I'm curious - you must have hundreds of thousands of miles on your '08 for an electric water pump to fail ... of course I'm being sarcastic and somewhat discouraged (for you) about a failure that indicates to me (?what do I know?) an under-engineered and over-priced component.

Technically, my pump did not fail. It is noisy at times and the indy tech left it up to me to have it replaced or hang in until it fails, whenever that might be. In hindsight, the pump has been noisy at times for well over a year, but I could not pinpoint the source of the occasional noise until I ran the bleeding procedure after replacing the coolant.
I average only 5 to 6000 miles a year lately and the car now has 36K miles on it. So the performance of this pump is disappointing. The F10 N55 engine has a revised water pump which is recommended for the E60 N54 as a replacement. Keeping my fingers crossed.
