Experiencing the classic sluggish accel. Thread was great help. Dealer ordered pump based on print out of this thread's posts and my experience with the car. Tech said he ran into this a year or more ago in CA at the dealership there. It was early for this issue and they had to get a guy in Germany on the phone to diagnose it. Tech didn't do the replacement so he has no experience on this replacement but from what I'm reading it's pretty straightforward. At least he understands and believes in the fix for this issue.

I have a noob question: Is this pump belt driven or is it electric? Tech assuming it's belt driven but I was questioning that if under the fender is the access area, could that be. Sounded like a electrical connector (electric power or sensor? which?) and two coolant lines were involved. Which side of the engine is this pump located? Tech was concerned about working on the hot engine (don't blame him) but wonder if the pump is not integral to the block itself.

Pictures anyone? I'll show them to the tech, If he's like me he can use all the help and info he can get. He's very open minded and receptive to info. The best kind of tech. I know he'll probably have service info when he's ready to put the pump in, but thought I'd ease his mind in advance as he thinks this is an all day or TWO job.

Thanks for info in advance!
