Water/coolant leak

[Stargate9610]

Hi all. I have a leak of some sort on my 2017 T6. I think it is a coolant leak somewhere in the system bit so far 2 separate garages havent been able to locate the source of the leak. I'll add some pictures.
I think that when the van is at running temperature, there is a small leak coming from under the EGR pipe/tube on the drivers side, and is blowing across the front of the engine. The water pump has been ruled out.
My current mechanic is thinking that there may be a split in the EGR pipe?
Any thoughts please?

You might need to pressure test the system.

But looking at those pics the leak may be external, as you can see the glossy shine of dried coolant...

Id clean it all off with break clean...

Then top up.

Then pressure test the system to see where the leak is coming from?

Thankyou. The mechanic cleaned it all this week as there were sooty deposits on the EGR pipe too. The plan being to see which parts get dirty first when driving around which might indicate where the leak is from. I don't think they have pressure tested the system yet though, so will suggest this.

Just as an update. I had the pressure test completed, but this didn't show where the external leak was. I also had an endoscope camera put unto the EGR cooker. This showed that the cooler was leaking internally. This has now been replaced at the cost of £890.00 (part, testing labour etc)
Afterwards there was still a bit of a leak in the engine bay, but I found a slightly loose fitting of one the smaller tubes. (Very top right of picture 2 above) sorted this and am now leak free.
