Jovill, sir no need to clean the manifold since maaga ka naman nag blank. Minimal pa soot deposit niyan. As with my experience with the egr blank, most probably you will get CEL from another problem not related to EGR blanking. So if you do get a CEL, don't remove the plate, have the code scanned first.
Only one point is needed to blank the egr flow. Yung mga n16, 12N, N9, etc. are just codes based on the EGR system illustration so that nagkakaintindi kapag naguusa regarding blanking.
Common points:
N16 is aka as egr cooler inlet
12N is aka as egr cooler outlet
N9 is aka as intake manifold egr inlet.
There is also one shop who does pipe delete of the pipe going to the egr cooler inlet as a way of blanking.
