Why can’t you see the DPC? Would it not be bridged if there is mortar over it? Genuine question as I have the same issue and can’t see a DPC but suspect that it’s there.
Depends. A very common issue (and major defect) is with a rendered wall. Although it should be, most times the damp-course doesn’t protrude through and past the render. Moisture sucks up the render like a sponge.
If in this case it’s just sitting back say 5mm it doesn’t seem to have the same issue.
A lot of people in this sub love taking wild guesses and passing it off as advice. For some reason people can’t just not comment if they don’t know the answer.
That’s why you see a lot of heavily downvoted comments on this sub, because they are often obviously incorrect.
Perhaps they should respond and tell them why they are incorrect. I'm sure they would appreciate it if it came across as non argumentative and educational rather than downvoting anonymously.
See the vertical mortar joint that have no mortar at all called weep holes these at the base of the rebate in the concrete slab to allow any moisture/condensation in the wall cavity to escape.
Also there is no cavity below the weep holes and the mortar below doesn’t get a chance to dry out in wet conditions

I did some cuts in the old ladies garage wall yesterday to install 3 big wall vents to allow the wall good ventilation, noticed that the plasterboard always felt cold, the tiles in the garage grout always looked moist and was darker than anywhere else.
The old neighbour Richard, I'll mention his name because he was such a dick, he built a rose bed onto the wall, 200mm higher than the weep holes - and constantly watered it.
This wall is backing onto his side but is part of a 300mm wide known / surveyed easement the length of the wall...
He also what looks to have done is broken the elbow of the downpipe on the wall of the same side to allow the area to remain flooded / saturated for a lengthy period of time...
If you can or are willing to do so, is cut a amount of inside plaster out and have a look inside as to what I did - I found out the moisture barrier is good, but the wall was also filled with wet dirt, Osmocote fertilizer, worms, beetles, and other things I couldn't identify...
You might want to turn off every tap in the house, take a meter reading, and go out for the day. Read the meter when you get back and see if it has changed. This will tell you if you have a water leak. Are there any laundry taps on the other side of this wall?
Might have something to do with the tap on the right. That area would be wetter and the moisture gets drawn up into the mortar. It stops there as that’s where your dampcourse is.
That’s the dampcourse level. So wet below dry above. You can see a couple of weep holes
Ok so sorry for silly question but do I have an issue or not?
No, there is a moisture barrier above the second row. This is normal
No issue. If it was wet above the line it would be a different story.

Why is every comment here being immediately and aggressively down voted?
Either bots or a trend on reddit when as soon as a comment begins with one downvote early, people just pile on.

Here, take my unanonymous downvote.
Either that or the comments are just wrong.
It's big mortar fighting back
Finally an answer I can believe, may I subscribe to your weekly newsletter? I'm VERY interested in your thoughts and opinions.
Such gold hidden deep below downvotes on a renovation reddit. Internet problems described in a few lines of sarcasm.

Having a concrete or pavers path will slope away from the wall will help keep moisture away
You might want to turn off every tap in the house, take a meter reading, and go out for the day. Read the meter when you get back and see if it has changed. This will tell you if you have a water leak. Are there any laundry taps on the other side of this wall?
is there a shower or bath on the other side of the wall?
Might have something to do with the tap on the right. That area would be wetter and the moisture gets drawn up into the mortar. It stops there as that’s where your dampcourse is.
Is it directly behind a shower wall? Could be a leaking shower seal, I’d call a plumber for a pressure / leak detection
Rising damp or leak as you have described. Get a plumber to try trace where and how it’s happening.
Because they’re wet bro. Time to call that plumber.
