This will undoubtedly be a familiar topic, which I have myself come across however I'm hoping to resolve an issue or two along the way at, hopefully, short notice.
The additive in my 1.6 TDCi had run out. Giving me error codes -
P1927 : Fuel Additive level too low/empty
P1932 : Fuel Additive low level
The "Engine System Fault" message on the dashboard after a few moments running was the initial indication of a problem.
I've now added approx. 3/4Ltr of additive to the tank (which is situated at the back of the fuel tank) but I am unable to clear the codes.
I have a "Ford-VCM-OBD" interface and software (Bought from the web) which allegedly clears the codes and re-reads them, however I cannot seem to clear the codes and the dashboard message. Previously, when the code first appeared I was able to clear it, for a few days.
I've tried the "Fuel flap" method, of which there is much talk ( difficult to find on the forums ) but that hasn't done the trick either. Check the status of the flap sensor, that's working fine.
Has anyone got experience of the software I'm using ? Am I doing something wrong ?
How reliable if the Fuel Flap method, Am I missing something?
