Nissan X-Trail - Water pump replacement 1.6dci - Lucas1502

Hello,

I have coolant leak in my Nissan xtrail t32. In around 500km coolant is going from Max to Min which is around 250ml. System was pressure tested and there was no visible leaks however there is some staining around water pump so I presume it's the source of the leak.

I have checked Nissan manual and they saying that to replace water pump engine need to be removed. Is that correct? Did anyone replace water pump in this model?
