Hi - got mine sorted. Seems to be quite a common fault on them.
Basically the ECU loses the unique identifier for each injector and so doesn't know which one is in which cylinder. Simply a case of reprogramming the identifiers in. (The id is written on the injector).
I say simple - I still got charged £93+vat. still better than ford who wanted £115 just to read the fault codes.
