Hi all 
  
Im having a nightmare with my 2002 auto import  
loads of fault codes and i think i need a new ecu 
nissan quoted me £1488 
ive found an ecu on ebay with all but the last 4 numbers the same  
will this work?  
can they be sinked to my keys fuel system ect  
ive seen stand alone ones but yet again big bucks  
any advice much appreciated
