As per Elsa diagram wiring checked. Fault code cannot be erased, comes back after start up. Will connect battery charger and rerun scan and post.

Either pump is faulty, wiring or ECU, did you simulate sensors/pump with decade box to verify wiring & ECU will vacate the DTC & did you measure resistance of pump?

FUSES?
Ground connections?

Also think pump or ECU? Don’t have a decade box. Not allowed to buy any type of equipment from VW/Audi in South Africa. Will need to source equipment overseas and import. No function on VCDS to activate pump. The contr unit is part of the pump (pump) inside reductant tank! Will have to remove the contr unit/pump from the tank (draining tank), and then disconnect pump to check resistance.

A decade box is just a variable resistor/capacitance etc. and can be bought as a generic tool, it doesn't have to be bought from VAG.

Example.......not endorsed!
