I had scheduled a mobile service on Sunday night with a note asking if I was eligible for HW3 upgrade. They sent me a message on Monday morning telling me that I am on their list for the upgrade but will have to visit one of the service centers to get it done. So I have now scheduled for next Wednesday at Dedham center. I was initially worried if they would have the parts in stock in such a short notice, but looking at the update on this thread, I don't have to be worried it seems. Mine is LR-AWD, VIN in 71k, delivered Sept 2018.
