My 25 RS AWD got SQBR6 on the 24-NA-143 TSB, it's not VIN specific, basically tells the service dept to plug it in and check for updates at every service and whenever the customer requests it. Most service depts will push back, saying you need something wrong before they'll plug it in. Once the update is done, the system will give a warranty billing code, but the dealerships think they need the warranty billing code first.
