Probably75 Posted March 14, 2015 Share Posted March 14, 2015 I wonder if anyone could help me out. I've got a 51 plate 1.8 tdi focus. All of a sudden it just cut out. Had as out and they found the codes p1664 and p1564. Can anyone shed light on these and what they could mean.

Tomsava Posted March 17, 2015 Share Posted March 17, 2015 P1664 FIP (Fuel Injection Pump) malfunction (possible air ingress in low pressure fuel side) P1564 FIP (Fuel Injection Pump) requesting reduced fueling mode I'm guessing the fuel pump is your culprit Quote Link to comment Share on other sites More sharing options...
