Hi, I have a Mercedes Benz W245 (year 2009). I had an ELV (or Electronic Steering Lock) issue recently and hence ended up disassembling part of the steering wheel (I am a newbie and only realised later that I didn't need to disassemble the steering column to remove the ELV, because my ELV was anyways in an unlocked state). My battery was disconnected during this time. My ELV has since been fixed and I'd put together the steering column as well. After this, I got an ESP malfunction issue, Run-flat indicator malfunction issue and the SRS warning light as well. The ESP and the RFI issue was resolved after I adjusted the steering clock spring slightly. However, the SRS warning light continues to stay. I used Launch CR629 OBD2 tool to scan for DTCs related to SRS and I got the following. I am unable to clear the DTCs. Please can you advise.

Additionally, I cleared a couple of stored DTCs specific to ESP today and they haven't re-occurred since.
DTC 5AE6 - [Check power supply of component B24/15 (Micromechanical yaw rate sensor AY pickup).] or [Check power supply of component B24/15 (Yaw rate, lateral and longitudinal acceleration sensor.)]
DTC 5C3F - Fault in component N80 (Steering column module)
