If its earlier than 04 you should be fine. The aset's and MP's are junk. I never had a problem with anything earlier than this e6/e7/etech. I work on a fleet of 01-current and the 01/03s are the only ones that don't have constant engine related problems. Been here sine 2005, so I've seen the 'good ones'

Kind of hard to understand exactly where the leak is.. Is it possible one of the EUP holddown bolts snapped? This is a fairly common occurance. Should be more of a fuel leak though.. Is the Leak above the air compressor but below the EUPs/fuel gallery? Only other thing I could think of is the bolts that run through the side of the block into the mains. Maybe one snapped? These are lower down near the pan though.

Can't comment on the pro-link but I do use the usb link with techtool and its been a pretty quality piece of equipment. Nexiq makes good products.

Probly have this sorted out by now but could be the coolant temp sensor or the wiring to it.
