Replacement Bosch motor

[boomdocker]

Looks like my motor (Bosch Performance Line CX 75Nm) has crapped itself
Out of warranty, so my only option seems to be to try to find a replacement online somewhere.
I see a good few for sale on ebay
So is it just a matter of buying a replacement, then bringing to any LBS with Bosch diagnostics to program it and away we go?
Any potential pitfalls?

I have bought two performance line from 4mybike.de on ebay.
They will ask for information and, for an extra $, will send it pre programmed for your bike, so its basically plug and play.
