I have 245/35/19 tires, but it's not a tire issue, it's due to my reduced mobility.

Hello everyone, I'm reaching out to the community for some specialized guidance on modifying the steering assistance maps on my VW Golf VII. I have a physical condition/disability that significantly reduces my arm strength, making the standard steering feel on my car, even in Comfort mode, quite heavy and tiring to manage, especially during low-speed maneuvers and parking. I've read through this thread and was particularly interested in the experience shared by @Frankenfurter about changing the steering rack parameters using VCP/ODIS to alter the steering assistance levels. This seems like it could be a life-changing modification for me. My vehicle has a steering rack with part number 3Q0909144K (hardware 3Q0909144H, EPS_MQB_ZFELS system). My goal is to achieve an ultra-light steering feel, making it significantly softer than the factory Comfort mode. I would like it to be a permanent setting (not dependent on the driving profile) to ensure consistent and predictable assistance at all times. Based on my research, I understand the process would be: Use VCP to read the current parameterization file from my steering rack. Find a suitable parameter set (SGO file) from a lighter MQB vehicle (like an A3 or Octavia) that has a similar rack and provides a "softer" steering map. Flash this new parameterization using VCP and perform the necessary calibrations (G85, end stops). My specific questions for those who have done this: Compatibility: Has anyone successfully loaded a "softer" map onto a 3Q0909144K/H rack? Are there any known issues or specific firmware versions to avoid? Source of maps: Which vehicle maps (Audi A3, Octavia, etc.) and what "level" numbers would be the best starting point for achieving maximum lightness? From what I understand, lower numbers mean less assistance, so would a higher number provide more assistance (softer)? Procedure: Is the workflow I described (read -> find matching SGO -> flash -> calibrate) correct for my hardware? Are there any specific security access codes or special steps needed for the 3Q0 rack? Risks: What are the main risks involved in this process (beyond the usual flashing risks)? Could this cause any errors in other systems like ESC or ACC? I have access to VCP and a compatible interface. I'm comfortable with the technical process but want to ensure I have all the correct information before proceeding, as this is a critical accessibility modification for me. Any advice, experiences, or pointers to reliable sources of parameter files would be greatly appreciated. Thank you in advance for your time and understanding.
