The additive tank normally has a LIN connection to the BSI.

PSA dont use wire colour coding, they use codes printed on the wiring.
If it is the type of tank with the 3 pin plug pin 2 is normally the LIN connection.
Are you getting no communication with the tank?

First check is to confirm you have a power supply & earth across pins 1 & 3.

Yes, you should have battery voltage across pins 1 & 3 with the ignition on.

To check it properly you would need a wiring diagram to check the LIN wire between the tank & the BSI, I suppose you could also scope the wire & see if there is anything going down it. If you have physically checked the wire as far as you can the chances are you need a new tank/pump unit. Certainly not uncommon.

Just to confirm was it a brand new genuine part?
