Opel Astra J 1.7 cdti p1297 help!!

Hello, i have in my garage opel astra j 1.7 cdti 2012 with fault code p1297 fuel pressure regulator not learned/programmed. On car already is changed three fuel pressure regulators and no luck check injectors and everything about fuel line.Car wont stay on idle only if gets very warm can keep a little idle but not stable. I try to adapt fuel pressure regulator with launch autocom delphi wurth original with no luck. Any help?

we had the same problem on car like that and kts ,launch,opcom couldnt do it,we did it with delphi 2015 without any problems.

i will try again

I know is an old thread but i a
Runnjng in same problem. To learn the sensor you need. To start the car, mine is not starting and i read 0 bar of pressure. . Mechanically it looks like is at least 100 bar . Very weird. Anybody run i to this kind of problems ?
