As far as I can remember, because its a tii, the pump is electronic, as opposed to mechanical pump on standard 2002. We had the 'original' pump replaced last year, and ever since installation the newie has been quite noisy, the volume (noise, that is) varies a bit, mostly it seems to be depending on whether the engine has been running for a while, say, when I've been for a bit of a spin its really noisy, like when I'm iddling at the lights I can hear it whirring from the cabin very easily-it competes with the radio. My understanding is that it should only be working hard enough to maintain fuel levels getting to the engine,and then just circulating excess fuel, but it seems to be sending fuel around at a much faster rate than necessary (I'm guessing). I'm afraid its going to wear itself out or something! Is this normal? - when the local Bosch dealer listened to it he just said: "so??" really helpful! Does anyone have any advice??

Thanks in advance
Oliver
