Ford Focus 1.6 TDCi mot. G8DB year 2006 has this problem, at idle and sometimes also on the move after a few minutes of running it suddenly switches off. In dignosi presents the following errors P1295 P1552 P1553 P1554. Injectors dyno tested at the pump shop with positive result according to him they work fine, I also reprogrammed the codes. Checked injector harness connectors, OK. Tried electrical signal of injector control with oscilloscope, signal ok until car shuts off. Tried another pressure sensor on the rail as some cars had problems on the same, but nothing to do. The car continues to switch off in the same way. Once switched off, it restarts immediately on the next start up, then after about 5, 10, 15 minutes it switches off again.

I await your advice.

Sincerely yours.
