[mk5_fiesta]

Hi all I recently had the aa out the other day the problem I had was my focus 2009 1.8TDCI my car was going into limp mode I had a message on dash saying engine malfunction and the traction light would come on.

so the aa plugged in there computer and it come back.....

P0204 - injection cylinder 4 open circuit 

P1201 - injection cylinder 1 open circuit ground short 

So are these easy to replace myself I do have some basic knowledge and I have bought reconditioned injectors but the aa guy said these will need coding once replaced

Thanks in advance

Can you not try cleaning injectors and replace seals?
