Water Pump May Develop Coolant Leak on BMW 325xi

The low coolant light may illuminate and/or the engine may overheat as a result of a coolant leak from the water pump. The leaking pump will require replacement and the entire cooling system should be inspected for leaks as it is not uncommon to find multiple leaks on higher mileage vehicles.

Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

Driving when engine light came on (yellow) then switched to red. I then pulled the car over and did not drive it any further. Towed the car to the dealership. Repairs were in the $800 range.
2006 BMW 325xi 64,000 mi,
I had a warning lamp pop up saying my engine was overheating. I had to get my car towed to a dealer who didn't have time to look at my car until a few days later. He called back and said my water pump was defective along with other problems; he said I also had an oil leak due to a crack in some valve (?). He said the water pump would cost $1,276 to fix because it was "labor intensive" and the oil leak would cost over $1,000 also.
