When I first got my 300CD, I was worried that my AC would really bog down the car.
Nope! I notice very little difference in power!

Could be your pump is either overfilled, or on the way out...

I know this is a subjective discussion on what is "losing power", but suffice it to say, that my diesel engine loses less power than a gas engine when the pump is switched on.
