Hi all,
Had the yellow light come on, took it to my BMW indy shop, they replaced the water pump they suspected was leaking. I refilled (overfilled actually) the fluid. A few days later the light came back on.
My filler pipe is cracked and old (2007 335i). The BMW shop owner told me if he's going to take the wheel and panel off to inspect, I might as well order a new filler pipe they can replace. Those are $50 on Amazon, though, and I don't see how a leaky filler pipe would lead to the yellow light coming on.
Those lights come on only when the levels in the reservoir tank are low, correct? So how do I know I don't have a leak in the tank or the pump again? How would replacing the filler pipe, which just feeds the tank, help the situation?
Thanks!
If your going to take it apart replace the filler pipe, washer motor, grommet do it all
