OP,
You can step up the DPC if thats what you want. Best practice is to drill and inject at the same level from both sides of the wall.
Thank you for the new pic and info. I was the one confused , not you.
However, will you stand back & take & post a pic of the whole elevation from your window to the neighbour's window.
Its possible that you can cut back the yard wall (about 250mm) to line up with the face of your neighbours jog out - that would break the bridging effect of the yard wall - speak to your neighbour before doing anything to the wall: its a shared wall & they might also want to do something with the wall?
As regards the interior, why not take off the plaster to window board height.
If the above suggestions dont fully work out then by using a remedial mix to re-plaster or render it will give you 10 to 15 years of grace before any more damp signs begin to appear.
FWIW: your window frame should have been set back 75mm from the face of the brickwork.
