My Fiat Grande Punto engine management light came on this morning. Took car to local garage who plugged it into a diagnostics machine. Came back with error code 14H/321 (an undocumented error). Does anyone have any idea what this code means. Thanks[
 
AGAIN !!

no clue here about what engine/power etc.

Any other symptom that you could describbe ?

1.2 petrol, 65bhp. No other symptoms. Car drives fine, just the EML on

Thanks

Hi Ross and welcome on board !

a correct OBD reader would tell how various parameters were when the MIL popped-up, if the light is still ON, the error is still present (or at least stored in the ECU memory). Would be nice to have the readings before attempting anything... Got some ££ to spend ? Get an ELM interface and the MES licensed software for about 80€ total; well spent money if you own a Fiat ;-)
BTW: no clue about this 14H/321 code; could be coming from their diagnostic machine itself aswell !!

Regards, Bernie

Yeah,

same-ish issues, same-ish replies... Seriously thinking about the cut & paste technique ;-)
