I replaced one of two fuelpumps a couple of months ago on my 93 850ci auto. Today I am replacing the second one which went out on me this weekend. The car went into 6 cylinder mode each time. Is it normal for the pumps to go out after eight years? Is it a milage thing. The car has 46K on it. Anyway there are only two and now they will both be new. Can I expect any better performance now tha they are both fresh? Thanks for the tips...

As far as I know we only have one fuel pump on our cars. There is a right and left sunction unit and a right and left sender (for the fuel gauge) but (AFAIK) only one pump. The pump is part # 16 14 1 179 710 and it is on the passenger side of the car under the back seat. The suction units are 16 14 1 180 469 (right) and 16 14 1 180 487 (left). I'm surprised that the pump would go at your low mileage, but I guess it's possible. If they replaced the pump last time then maybe you have a problem with the left pickup (suction unit) and if that's the case it is much less expensive than the pump itself. It might be worthwhile to check the part number of the item they replaced and ask them for the number of the item they suggest replacing now.
