XZBMW  E90 CAS3 fried
I got an 07 335i with cas3 fried, owner opened up cas module and saw burn marks / tested with multimeter and confirmed it is fried.

Car does not start.

What is needed to fix this issue.  Owner got a used CAS, no keys, 

Can anything be done or does he need a CAS+MSD+Keys to make it work?

Burned trace?
Just clone it.

Exactly, it is unlikely that the MCU is fried. Try to read it with any programmer and if possible then You may do clone.
