As of today, JLR published several new documents regarding the battery recall in Topix. They updated the original bulletin (attached), and also provided dealer service instructions for updating the BECM software. The customer letter and a Questions & Answers document were also published, and all are attached here. According to the QA doc, the new version of the software is now available. I also noted that the H441 service campaign is now showing for my vehicle, whereas it wasn't previously.

I have my car booked to go into the dealer on Friday, and will report back on the new version. I'm already running the very latest BECM software, so it will be interesting to see how many modules get updated.

The process has gotten a little easier for dealers. Cars that get modules identified due to H441, H459, or H471 do not need a TA opened. Dealers are instructed to use TOPIx Cloud to identify cell modules, order parts, and fix the cars. Opening a TA is only needed if they truly need technical assistance.

H484 still requires a TA to be opened only if fault code P1B48-00 is found.

This eliminates a bottle neck of opening TA and waiting for response and authorization to order parts.

FYI. We all know Jaguar allows dealers to repair the HV traction battery when bad cell modules are detected. Taycan vehicles recalled for the battery defect require the traction battery to be removed, crated up, shipped to another company (EV Battery Solutions by Cox Automotive), repaired, shipped back and then reinstalled. EVBS determines how many to replace.
