Mine recently failed and dumped over a gallon of fluid. I pulled the pump out of the grommet and it game out with virtually zero resistance. I wrapped the pump with Teflon and will fill the reservoir to see if it holds. I may re-do the fix with some heat shrink tubing if I don't buy a new grommet/filter. Since there are three I'm more likely to patch with Teflon vs. replace I've done that in a few places on the two e53 we own.
