Coolant leak - Investigation ideas

[Crippso]

As @roadtripper mentioned above it sounds like you stopped during a DPF regeneration. Carista Beta will show when the last re-gen was carried out, plus many other useful functions. An engine coolant system temperature will briefly rise just after shutdown as the airflow over the radiators is stopped and the engine is still dissipating residual heat.
My advice is still as Post #4.

Thanks @roadtripper and @DXX I don't have carista but did order one yesterday funnily enough. I'm no mechanic but figured it would be maybe useful. So I don't know if it was doing a regen. But have read similar on other threads so makes sense. It's booked in now with VW at end of the month. Hopefully they'll be of the same mind around the EGR @DXX. I'll certainly mention that.

It’ll be much cheaper at an independent VW specialist.

Hi all,
So the van went into a VW commercial van centre today. They called at lunchtime to say they found the problem. Confirmed coolant leak in the EGR. Whilst not ideal, I'm just happy to now know what the issue is. Hopefully that will solve it.

I know a few people on here suggested it would be that. So you were dead right!

Thanks
Stuart
