You may have to remove your EGR components to get to (& inspect) the hose(s) that is/are leaking at the back of your manifold.

In theory you shouldn't have had to remove anything to do with your tubocharging system in order to replace your water pump. I'd suggest that you visually inspect around the area of your water pump to ensure that everything is plugged in on the harness (eg. your wastegate VSV). If you don't find anything obvious, you'll probalby have to go through all of the troubleshooting steps in the TSRM...
