Engine management light

[Rab Kebab]

Has anyone had issues with the engine management light coming on and off intermittently. Had car in garage and and on laptop but unable to find problem. Car runs fine and no notifications coming up either. Anyone experienced this issue?

Welcome to the Forum

Hmmm  I use BMW ISTA/INPA and it will normally record all faults in the cars history even "Not present faults" unless they have been cleared by the operator. Many people using Diagnostics start by clearing all faults, then run the diagnostic to see what returns. The problem is they have also cleared any history so if the issue is intermittent any trace is gone to.

EML is triggered by all sorts of issues from an Air leak to a short or poor earth in the loom to one of the sensors, sensors seem to either work or not so while I would test them I don't dismiss them, O2 sensors have a life so dependent on mileage and assuming no air leaks or vacuum leaks my testing would start there.

Unfortunately it can be an expensive process if your paying an hourly rate

Good Luck
