Replacement CEM
 

Does anyone know if a replacement cem from a similar car with a slightly different Volvo part number will work if I send it away to have the software swapped over? Both have the numbers CG9T-14C256-FA number but the actual Volvo numbers are different. Mine is 31343337 and the other is 31314511. My car is a V60 1.6 drive e the donor module is from an s60 1.6. The layout looks exactly the same.
