Audi A4 TDI 2.5 V6

Finally found the problem of my non starter - dying lift pump in the tank.

Managed to get the sender unit out and placed it in a bucket of diesel. Attached a direct feed to the pump...... nothing

Took the pump out of the housing and I'm wondering if i can just replace the pump instead of the whole unit. Its part number is 81397019 which i will check with the dealer tomorrow.

Has anyone had any similar experiences....
