Citing your own work that doesn't contribute to the current work should be seen as wrong. That is improper self promotion. Citations, whether of yourself or others should be done to support the arguments of the current paper.
Citing things not relevant is a disservice to readers.
Use citation for the purpose for which it was created: allow the reader to follow arguments back to their source.
The exception would be a survey paper in which you are simply gathering the important documents of some subfield. But for a paper that hopes to advance scientific knowledge, leave out the things not relevant to the conclusions. You cite yourself in such work so as to avoid self-plagiarism.
Needing to "promote" your own work also seems a bit odd to me. If the work is good, it doesn't need promotion. The work should stand on its own. Or not. Spend your efforts on doing good work, not on advertising it.
