Hi I've got an anniversary Tdi I stated it up this morning as not used for a while left it running it cut out now just cranks over plenty of diesel in it , a few months ago when I was out I got in and it wouldn't start just cranked over (same fault code as now) I disconnected battery then it started fine done around 1000 miles since no problem code shown is 18072 control circuit for PD injectors :electrical malfunction p1664 . Any ideas appreciated . Thanks
