You're right. Your issue may have nothing to do with the EGR. It could be a clogged injector. Or a sensor issue.
We're mostly van owners here, not mechanics, so mainly provide advise based on our own or other users experiences.
We can help with fault codes, using VCDS etc. We can advise which are the best wheels or tyres. Or which is the best camping stove!
When it comes to issues with no obvious cause then it's more difficult to provide a suitable solution.
If this was happening to my van I would try an injector cleaner to start with. You can get a bottle from VW for about £15 which is supposed to be quite effective.
Good luck getting to the bottom of it.

Can you not look at the duty cycle of the EGR whilst on cold start? The EGR usually duty cycles initially and if the engine isn`t being driven it will close it to assisit engine warm up. You have live data to look at.
That wasn’t my question, that’s what live data is for. Codes can be deceiving at times.
I blanked the egr off and started the van up when cold ii still ran like a bag of spanners so the egr isn't choking the van I have checked live data at tickover and at 2500 revs on this van and a known good van all data is same the only thing that was happening was the ecu would cut feed to to turbo solenoid which would then drop the vacum to to the tubo actuator if I manually actuate turbo the turbo stall flutter doesn't happen
