VW VOLKSWAGEN POLO MK5 1.2 TSi Engine ECU Swap

[tobytronicstereophonic]

I am swapping the engine ECU on my niece's Volkswage Polo 2015 1.2 Tsi Petrol. I have been offered a speedo, ignition lock/key, ECU, fusebox and ignition barrel/switch. Does anyone know if I need further items?
I'm hoping for plug & play...
ECU is definitely fried and have tried the repair route to no avail. thanks in advance.

Probably easier to clone the existing ECU rather than risk replacing all of that (and the ensuing nightmare of coding, faults codes, incompatbility...).

Virginised, used ECU would be second choice.
