1996 BMW 328 Automatic 140000 miles
My son had a 1996 bmw 328. Check eng light was on, needed to get smog checlk.
went to repair guy, he found brown water/rust? Was in the air punp and filter was wet and filthy. He replaced the air pump (part $275). Check eng light is now off. But, he didnt know why water was in it, my concern was if he doesnt kmow why water is there, then what stops water from reappearing. And can that redamage the newly replaced pump/filter?
he said he could check (dont know part name, but it is about a foot away from filter, down the ridged hose ( smaller black round unit about 3" in diameter).
left the car with him to replace unrelated item. Where do you thinik the moisture would come from? And once it is fixed, how many miles required to smog check with a smog check only facility on a bmw? I have been told from 20 miles to 150 miles from 4 diff people
