Got car back this morning. All well and car valeted so that was good. On all the blurb it says ‘Replaced turbo and all associates parts as per ELSA guidelines.Ran GFF, faults cleared.Set vehicle oil pressure to ‘run in’ mode .This will automatically revert back to normal after 1000km .’ Don’t know what ELSA guidelines are but presume it is some standard . But why the oil pressure set to run in mode ?
