I have had two repairs on my e90 that involved the cooling system. About a year ago BMW replaced the thermostat because it was leaking slowly. Then, several months after, my AC evaporator leaked and was replaced. During the AC repair, they had to disconnect the heater hoses from the firewall.
The thing is, I *still* smell antifreeze in the engine bay. To my nose it smells like its coming from the top of the radiator on the passenger side, but I guess it could be anything in that area (hoses, water pump, etc). I took it back 2 or 3 times and they say there is no leak anymore. They have hosed down the engine bay several times. Yet every time I drive the car, I get the antifreeze odor.
Following the repair of the AC its the same thing. I get antifreeze smell on the driver side from the area under where the power steering reservoir is. I don't see any hose connections there, but I do see two heater lines run through that area and there is a clip to the side of the engine bay. Again, according to BMW no leaks apparent, area washed multiple times, yet antifreeze odor persists after several months.
This can't be normal, can it? BMW runs a pressure test according to their procedure and says no leaks. But if its not leaking, why am I still smelling it months to a year later? In fact, if I spill antifreeze on purpose near the reservoir I don't even really smell it for more than a couple days and it certainly goes away if I flush it down with water.
Is there something else that can be done to get to the bottom of this?
