2024年5月18日 · Hello there, my shop is currently working on a 2020 Tesla Model 3 with MCU version 2. The date of manufacture is 12/2019. We are having an issue where the A2B bus is being shorted to ground. Resulting in the overhead microphone and rear amplifier not working. We have purchased an identical...

2024年12月9日 · For MCU, they have MCU/1, MCU/2, and MCU/3. For Auto Pilot computers, they had AP1, AP2, AP 2.5, AP3 and AP4 with AP5 coming in the following years. What you have purchased is MCU/2. I'm guessing you have the older AP2 or AP2.5 which should have been upgraded to AP3 or can still be upgraded to AP3.

2015年8月18日 · I'm considering getting the MCU update to my 2017 Model S. Does anyone know if that upgrade would take me to MCU2 or MCU3?

2019年8月6日 · I remember old versions of software ran great on the MCU1, and it was very responsive. V5 was brand new when I got my car. MCU reboots took like 15 seconds! They kept "upgrading" and everything got progressively slower. Reboots take forever now; I'm on MCU2 . The software became bloatware.

2023年7月17日 · Just a post to give my experience upgrading from MCU1 to MCU2. My car prior to upgrade: 2017 Refresh Model S, MCU1, AP2.5, Sunroof, Sirius XM, AM/FM, LTE, FUSC, WiFi 2.4GHz, Free Premium Connectivity, EMMC Recall active, Autopilot (not FSD) My car Post Upgrade: Still 2017 Refresh Model S...

2019年9月12日 · I started to get bubbles on the MCU a month ago. I finally had the time to remove it and fix it. I used gorilla epoxy, it's rated for -23c to 85c or so. I applied a layer of the epoxy around the edges of the screen and since then I haven't received any new bubbles. Now I need to figure out...

2024年11月20日 · Rebooting the MCU often times fixes this inability to communicate with the car from the app. It has to be done pretty regularly on these older cars as compared with the new ones, unfortunately. Try that before including it with your service request because there's no fix for (largely hardware related) that and it's an ongoing issue outside of ...

2020年4月10日 · I created a service request to update to MCU2 + radio for my 2016 MX, currently with AP1 and MCU1. I was expecting $1750 for MCU2 + $500 for radio. Estimate came with $2250 for MCU2 + $500 for radio. I pointed to the language on the website and they replied that the $1750 price is only for MS...

2020年4月10日 · Here's my story of my DIY HW2.0 retrofit for MCU2, IC2, TUNER2, and FSD Computer: I want to begin this post by offering the most honest caveat I can: I do not encourage you to repeat anything I have done. In fact, now that Tesla is offering the MCU2 and FSD Computer retrofits officially, I...
