Five problems related to water pump have been reported for the 2007 BMW 335. The most recently reported issues are listed below.
My vehicle displayed a yellow warning that the engine temperature was high, and that the car needed to be driven at moderate speeds because the engine was close to overheating. I decreased my speed from 30mph to 20 mph, and about 30 seconds after driving the car at 25mph a red warning light came on that said my engine was too hot, and the car stalled on me. I received no prior warning regarding an overheating issue. Luckily I was not on a highway and was able to pull to the side of the road. I got my vehicle towed and I was told by the shop that the water pump failed, and that I needed a new thermostat.
Car went into limp mode due to excessive engine temperature detected. Cause of engine overheating was a faulty electric water pump. Dealer replaced the water pump and thermostat.
I have owned this 2007 335i for 2 1/2 years. I am a 59 year old female that drives very conservatively. In the 2 1/2 years that I have owned this vehicle, the fuel pump has been replaced twice. Four months ago the injectors had to be replaced and this past Friday the electronic water pump and electronic thermostat had to be replaced. Not typical of any BMW I have owned in the past 12-15 years. I contacted our local BMW dealership and they knew of no problems with this particular model. I contacted BMW today regarding this model and they took the information for review which to me means file 13. BMW knows there is a problem with the water pumps and the thermostats on this particular model and they choose to do nothing about it. They also know there is a problem with the injectors and they choose to do nothing. I was told that the NHTSA makes the determination on all recalls not the individual car makers.
I picked up my car from the dealer after replacement of the electric water pump. I drove home and parked the vehicle. 4 hours later my neighbor alerted me to an engine compartment fire that completely destroyed the vehicle.
Water pump failed while driving and car would not exceed 5mph. Postings online show this is a common issue (possible recall issue like the fuel pump). Car was towed to the dealer and water pump was replaced for $1033.
