Eolys replacement tank

[jw4821]

Has anyone got a copy of the official lexia procedure from the manufacturers for replacing the Eolys tank? 

I'm having nothing but trouble with mine. Wiring has been tested twice and is OK. 

The error given is fault in multiplexed pump. When tested, the pump operates, pressure is shown in the diagnostics and fluid comes out. 

The unhelpful ar*eholes at Neo brothers assure me that the part isn't faulty. However when I check the parameters with the pump running as part of it's 10 min priming procedure, the pump is showing as inactive, and the additive priminng status is showing as invalid value despite the pump clearly running. Photo attached. 

The error always comes back after refuelling, so I'm wondering if the van looks at these values to determine if the dosing has been successful? 

Either that or I've not learned it to the van correctly! 

Any help is appreciated!

Can you set the pump to active within Lexia?
My lexia broke, so I can't point you to the setting.
I then went with a Topdon Artidiag BT800, though it's lacking the bidirectional features needed for Eolys.
I replaced my tank last year and told the car to initialise it using a Thinkdiag*, or the Topdon Topscan - can't remember which.
It worked fine and has now started throwing errors again.
Tempted to get it coded out, or just sell the car due to the emissions nonsense on it.

*The thinkdiag is capable, but the VIN search is slow as hell compared to the Topdons.
ALso tried XTool A30 and that was poor, with most functions not being available.
