Sausage Posted June 3, 2019 Report Share Posted June 3, 2019 The first ones are injectors, the fact all 4 are affected says electrical fault like wiring, control module etc. Check the fuses. http://wiki.ross-tech.com/wiki/index.php/17648/P1240 The 01312 one looks like data bus: http://wiki.ross-tech.com/wiki/index.php/01312 Last one is airbag.

mk2 Posted June 3, 2019 Report Share Posted June 3, 2019 Could be a main power relay. They generate the same problems and fault codes. Yeah, could be a fuse. Fault to ground could mean that the injectors are actually ok, as is the wiring, but the 12v supply isn't there. So the ECU thinks that the supply has been shorted out (to ground). It should say, short to ground or faulty supply... Quote Link to comment Share on other sites More sharing options...
Skezza Posted June 3, 2019 Report Share Posted June 3, 2019 Like most fault codes, always suggest clearing them first, see what returns. Your airbag fault for example is basically a false positive. Quote Link to comment Share on other sites More sharing options...
