The 2008 X5 3.0L started to sound like a jet engine with the super loud fan noise.
I thought the car was going to blow up.
Took the car in for repair, and luckily the engine hadn't overheated yet.
They found that the water pump was faulty, which caused the wiring to burn out, and caused damage to the fuse box.
If I had driven the car any more, it would have caused significant damage to the engine of the vehicle.
After the $1400 repair for water pump, thermostat, and the fuse box wiring, I found out there is a recall for only the V8 - V12 engines for this car???? (just type in "2008 BMW X5 water pump recall" on google)
I find it very strange that they would only recall the other engines that are not as popular when the 6 cylinder has more cars on the road.
Also, I just found out there is another recall "DMTL Pump" which causes the engine light to turn on and cause system failures. (This prevented me from getting my emissions passed)
After speaking to several BMW reps, they informed me the recalls only occur when a sufficient number of people complain about it. 1-800-525-7417
Hopefully, we can get enough people with the problems to raise this issue with BMW.
