a car that can't do the throttle reset.
Slight performance decrease at times.
04 C32, low miles. Lately I have been noticing that the throttle response isn't as strong as usual. When I push the throttle, normally the car moves strong and confidently. But lately at times it is SLIGHTLY sluggish. Definitely not limp home mode or anywhere near that bad. Very slight. Then thru the course of the drive it will return to normal.
I know it seems vague, but I think that if anyone understood it would be a fellow C32 driver. And no, I am not getting any error messages.

mostlikely all you need to do is reset your ecu.
While you drive ECU learns and adopts to your driving style.
To reset ECU just turn ignition on ( do not start engine ) and depress throttle ( just floor it ) hold for 5-10 seconds and start engine. Your car should get the edge back.

Well, it didn't do anything good.
The other day I lost power. On the highway... cruising around 65 and floored it. NOTHING. Car didn't rev, and it didn't pick up speed at all. It was like I wasn't hitting the throttle. Something is completely fubar.

Drive your car hard for few minutes, if you loose power and after another few minutes power is back- classic symptopms of failing I/C pump.
easy to fix DIY, almost impossible to convince dealer to repair it.
Good luck,

If it's a complete loss of power, it's probably the intercooler pump. If it's 'slight' then it's probably just the fact that the transmission is deciding to go into a higher gear and bogging. If you manually shift it, it should rock and roll. If you manually shift it and it's totally sluggish, and this behavior is complete or intermittent, I would suspect the IC pump. It just happened to me, so your last couple posts seem to describe what I've been feeling as well.

When the IC pump goes out, at least on the E55, the car will still build revs and increase speed, but its like you're in one of those commercials dragging a 10' anchor or a piano. Parts of his problem sound like the IC pump, but I would think that this was something different.
