I'm literally stuck! I'm currently rebuilding a mk2 seat leon 2010 Cr170 cega and the wiring loom is done and been double checked against another cega for mistakes but all is correct. We also checked for any breaks in the wires but there's nothing. The car just won't start but cranks. Do you have any idea on what it could be please or anything I could try? We checked the relays, fuses and put vcds on it and the code it keeps throwing up is 01314/004 no communication.
