ISTA/D ABL:Charging pressure control deviation - Lsc - 15-08-2019
When I try to execute:
ABL Charging pressure control deviation in ISTA/D, to check for a boost leak, ISTA doesn´t seem to give me the option to perform the check anyway, even if there are no fault codes stored.
Is there another way to check for a boost leak with ISTA? Or a workaround?
(Vehicle is E71 XDrive40dx with N57 twin turbo engine)

Create an error by advertently causing a boost leak!! Then run test plan on the error. Once ABL starts, before the first test, restore charge pipe if that is how you decide to cause a fault.
