Looking up windshileld washer pump, I find that there are two aftermarket pumps made by Trucktec and another by Vemo. THey are less than half the price of the BMW pump, but I would like to know how good they are, this will be my 3rd pump and I am getting tired of the hassle to replace itGwynne Spencer, '97 540iA (Euro delivery, Aug. 28, 1997)
