Why water pump failure at low mileage?
What would cause a water pump to fail on m2 n55 with 17k miles never tracked city and highway driving in winter???

Strange, you would think if it was defective from factory it would have failed sooner. I've been driving for 50 years and had 1 water pump failure. Chalk it up to bad luck!

The M2C/3/4/ S55 engine uses a mechanical belt driven water pump so you don't see them failing early |

I had to have the electric water pump replaced on my 2016 Golf R at about 15k KMS and it's a chronic issue with the EA888. It seems like these electric water pumps aren't as durable as the old mechanical pumps.

Electric circuits are very delicate. Moisture, heat and impact shock can shorten their lifespan drastically. Also parts cannot be replaced individually. The whole circuitry has to be replaced. A car driven by battery won't last 20 years with continuous usage but an engine can run like clockwork easily during this timeframe with proper maintenance. |

Every BMW I have owned with an electric water pump has had the pump fail. 50% of the time I was stranded and needed a tow. I had an 09 X5 that went through two of them within 90k miles.
