Yes, it was a little bit hard, first you have to cross-loosen the bolts of the front differential axle to get access to the ISM, the problem is that there is enough room for a impact screwdriver.
After removing the bolts, you can push the axle to the front and now you have to loosen the 4 torx bolts of the heat deflector, again, you will need a small tool to get access to the upper bolts.
Finally, the easiest part, you have remove the harness conector, the 4 bolts that holds the ISM and the vacuum hose.
After replacing the ISM, the hardest part is that the bolts of the differential axle must be cross-torqued first with 20Nm and finally, 90 degrees. I suggest you have someone stepping the brake of the car to do this torque.
