Two problems related to water pump have been reported for the 2006 BMW 325. The most recently reported issues are listed below.
I have 77,000 miles on this car and the water pump has become defective as I began to seach online about this issue I see there are thousands of complaint about the same year and model of my car I beleive this part should be recalled.
Water pump and thermostat both quit working at the same time. Causing absolutely no warning on the vehicle until it started overheating and smoking while driving on the highway. Could of caused a serious accident. Needed to immediately pull to shoulder. Note: car has no oil temperature gauge.
