Sorry, i tried to PM but im not allowed as were not friends.
I had 2 boiler men out today who both agree with your diags in my thread at:
//www.diynot.com/forums/plumbing/is-my-diverter-valve-off-to-the-boiler-parts-heaven.329620/
that the primary HEX is all blocked up and thats causing my noisy boiler.
So the second guy who came out i tasked with replacing it, he went off to the merchants and brought back part number 064714.
Took it out the box, looked at it and said no its the wrong one.
Left and never came back, stil lwaiting to hear from him!!!!
I have found a picture of the HEX in my boiler:
http://www.vaillant.co.uk/stepone2/data/downloads/ca/42/00/turboMAXspareparts.pdf
Page 5 - the "tails" pointing down off the HEX look like that and back right is a sensor connector.
The one he brought back and said was wrong looks like:
http://www.uk-plumbing.com/vaillant-heat-exchanger-24kw-064714-p-32600.html
Just rounded down tails with no connector for sensors, but i can see sensor connection on the 2 pipes that come with it according to that picture??
Did Vaillant change the design of the HEX?
Does 064714 that looks like the second link fit my boiler?
As all images of 064714 i find look like it, different to mine.
Boiler details from the sticker off the back door panel:
