In this video I show the fault codes my client was seeing and also:

I discuss the diagnostics involved,
how to test without a scan tool,
the parts involved,
what causes the failures,
how to test on the vehicle,
where the components to test are located,
the tools necessary for the Job,

Just about everything you need to be able to tackle this job on your own, take a look and if you like it please and subscribe.

If you have questions or comments feel free to leave them as I see them as a way to help out, again I am not sponsored or paid in any way I just do this to try to help our fellow BMW fans.
