If they cleared the codes and only the SRS light came back on, I would check the connectors underneath the front seats and ensure that they are seated tightly. The connector will be yellow and black in color. It has a "tab" on the side that you can pull in or out. IF the tab is pulled out, the connector might be in there loosely and the "on/off or plugged in/plugged out" connection will throw a SRS light.

If you are still getting the codes you listed above and have changed the components related to them and still only have 1/3 the power that you should, more than likely your DME or main computer brain is not functioning correctly.

Also, I would check all of the connections in the engine bay and trunk, ESPECIALLY the battery terminals. Loose battery terminals can cause a lot of problems, especially on E46s.

Hope this helps, keep us updated.

Something is up if you have this many codes and problems.

Suggest you see my signature below for the Hidden OBC Menu and bring up the battery/charging Voltage directly on the dash.

Also check the ground strap from the engine to the body near the passenger side motor mount.


Also make sure you did not get water in your DME box.
