    Upgrade MCU1 to MCU2 outside Tesla Service Centre

    Hi guys, I’m looking for someone to upgrade the the MCU1 in my 2015 P85D Model S (AP1, HW1) to MCU2. I figured I could buy a compatible MCU2 from a 2018 car and send that with my MCU1 to someone to copy the data over. My issue is the eMMC has just failed (probs possible to recover the data) and...

    What to do when the App stops connecting AND my vehicle is in for replacement of the MCU (eMMC recall)

    I've searched this forum and the broader internet, as well as emailing and live chatting with Tesla about this. My 2014 Model S had the center display stop working. We did the VIN number recall search and it was obvious we needed to have the eMMC/MCU replaced. As you all know, you can only...

    MCU1 Bricked After EMMC replacement?

    I know this is beating a dead horse and this subject has been covered in numerous threads. As a long time lurker I haven't posted until now, but I'm kind of at a loss about this situation. I had been having issues in my 2012 Model S with the touchscreen glitching or acting up (no...

    Upgrading a dead MCU1 to MCU2. Cost? Warranty?

    I have a 2016 Model S with a dead MCU1. It died last week after some minor signs of eMMC degredation. This was prior to the warranty extension announcement. At the time I requested that they just upgrade to MCU2 as a fix. I figured if I was going to have to get it fixed I might as well get the...

    Blank MCU, indicating eMMC failure but EVERYTHING works?!

    Hi, Yesterday my car turned on as usual but the MCU display never came on, after a few reboots I figured the infamous eMMC issue had finally found its way to my car. After reading a bit on this forum I found some normal symptoms that indicates a eMMC failure, for instance the mph instead of...

    eMMC issue? Only the eMMC or more? And can 12volt battery cause issues?

    Hi all, first, I apologize if I failed to search existing threads and find all this info already. I did go pretty deep in the eMMC wiki sticky, which was very helpful. But it didn’t answer all my questions. I have a 2013 Model S 60kwh with about 54,000 miles on it. I did not have the eMMC...

    EMMC preventative failure/repair in Chicago/area.

    Since I am hearing lots of people's MCU going out because of the EMMC failure. Do we have anywhere in Chicago land besides Tesla service centers that can make such repairs or prevent such failure from happening. I guess they are getting full on early 2013 and 2014 models s? I have heard people...

    Hit by eMMC Issue

    I've been hit with the dreaded eMMC issue in my 2015 Model S P85D. I'm very disappointed that Tesla will not sell me an updated MCUv2 that fixes this issue permanently. They even acknowledged that it is possible but isn't available at this time. My question right now is what are my options? I'm...
