You can clean the PEM without disconnecting anything. With the car up in the air, you can remove the cooling hose and access both the inlet and outlet ports on the PEM. The cooling air just blows across the heat sinks on the bottom of the PEM, not the internal electronics, so you can get in there with a blow gun and not worry about damaging anything.
...hmm, this is a half done job then. the problem with dirt in the pem's is not the visible dirt (outlet), it's all that crap in the inlet where you don't get proper access without disassembling the megapole-block (black plastic base) and for that you surely have to take out the pem
