Hi Eric, Just had one with the EMS light on and same fault code, tested injectors and live data seamed ok. Diesel specialist looked at it and replaced high pressure pump, still the same. Eventually the ECU was flash updated at a Ford dealer (injection specialist had IDS but theirs did not have latest update!!) problem cured. The only difference with this one we could not find any driving problems. We suspect ECU update first may have curred it.
