Brain damage

Hi all 

I joined this forum in the hope that someone can help me, 

my 2015 Nissan quashquai 1.5 DCI N TEC has suffered a catastrophic fault in the ECU, 

it’s completely fried 

my mechanic has told me that the only solution is to take a full ECU kit from a donor car and put it into mine, and it might work 

as things stand, the car will have to be scrapped, so this is the last roll of the dice 

I was wondering if anyone on this forum has ever heard of this being done, and what components make up a full ECU kit.

any help would be greatly appreciated
