Review on 🚿 OTUAYAUTO 67126934159 Windshield Washer Pump - BMW 525i, 328i, 325xi, 325i, M3, M5, M6 Replacement - Washer Fluid Pump with Grommet by Tony Basler

The bushing isn't really the original, it's a bit smaller which could cause leaks so I used the original bushing. However, the pump does not fit as tightly to the original bushing and causes very little leakage. I've just used plumber's putty (or maybe duct tape) as a workaround and no leaks so far. As for the front and rear pump spraying at the same time, what I noticed in my case is that it only happens when the engine is off. When the engine is running, it works as it should. I suspect it needed a little more amperage to work properly. So far so good, but it's only been a week. Let's see how it goes and I'll update this review.
