    2013 12v battery in one word

    I've replaced it twice in my 2013. Wouldn't call it fun but it's not a big deal. A few cuss words and evil thoughts about the Tesla engineer who put it there and then I get it done.

    Gruber Motors responses to BMS_u029 error message

    Back before Tesla was forced to replace the eMMC boards for free Gruber offered an eMMC repair service. You had to remove the MCU yourself, then remove the eMMC board and mail it to Gruber. They would attempt to read the contents and put it on a new chip. If they couldn't read it they would put...

    HV Battery Replacement Guide For Early MS 85kWh Pack Including Part Numbers And Prices (April/May 2023)

    Yes, new instead of reman. Paid $19k with tax or actually $18,800 after credit card cash back. It charged to 267 miles at 90% so a little shy of 300 miles at 100% I guess.

    HV Battery Replacement Guide For Early MS 85kWh Pack Including Part Numbers And Prices (April/May 2023)

    Update on my new 90kWh battery: Did my first SC to see what charge speeds it has. Charged from 75 miles range to 210 and saw double the kW throughout the charging session compared to the old 85 kWh battery. Got 118 kW at 75 miles and still over 100 kW at 130 miles. Charging was still free as...

    New 2012-14 MS Tesla replacement pack?

    Yeah, that's me. My experience is the service advisors at the SC are remarkable clueless. The first one I talked to called California and then told me ALL replacement packs are brand new even if they say reman on them. When I expressed doubt he dug in. He had just talked to the experts and was...

    HV Battery Replacement Guide For Early MS 85kWh Pack Including Part Numbers And Prices (April/May 2023)

    Only 39k miles. Seems this fault is triggered more by time than mileage.

    HV Battery Replacement Guide For Early MS 85kWh Pack Including Part Numbers And Prices (April/May 2023)

    My new pack is scheduled to be installed end of next week. My old pack would max a 72 kWh urban SuC until 135 miles of range when new. After charge gate I see about 60 kWh at 70 miles of range and in the 40's at 135 miles. I'd expect the new pack to at least match what I had before charge gate.

    HV Battery Replacement Guide For Early MS 85kWh Pack Including Part Numbers And Prices (April/May 2023)

    My 2013 P85+ got the infamous bms_u029 "Charge level reduced" last week and after reading up on the forum and going back and forth with Tesla Service I decided to write up what I learned. Much of this info is available on this forum but buried in various threads. My hope is to make this post...

    MCU1: Black center screen / mcu failure caused by a faulty navigation MicroSD card

    That's a weakness in how Tesla implemented this. The actual nav data is on the SD card, but the information of what is on the card is stored on the main storage drive (eMMC). So now you have the situation that the MCU thinks it has maps but when it tries to access them on your new SD card...

    MCU1: Black center screen / mcu failure caused by a faulty navigation MicroSD card

    Yes, that is odd. Mine had 2x 8 GB partitions with squashfs file systems. One partition was OK and the second heavily corrupted due to the card failing. Maybe your card has failed to the point you don't even see partitions. My understanding is that if you're not due for a map update it won't...

    MCU1: Black center screen / mcu failure caused by a faulty navigation MicroSD card

    You can probably do 2x 16 GB but it doesn't make a difference, only 2x 8GB will be used. Maps are in the squashfs file format which is a compressed read-only format. Once maps are deployed on the card they will always be in a 8 GB image.

    MCU1: Black center screen / mcu failure caused by a faulty navigation MicroSD card

    It was posted a while back so I think luckyluke is ok with me reposting it. To be clear: This is not my work, it was made by luckyluke. Note: I had to add ".txt" to the filename so the forum accepted the attachment. You should remove ".txt" before using.

    MCU1: Black center screen / mcu failure caused by a faulty navigation MicroSD card

    My SD card failed while downloading an updated map. Once I installed a new card formatted by nav_SDcard_format.sh it started a download of the new map automatically. Once it finished downloading it said it was ready but navigation didn't start working until the next morning. There is some sort...

    MCU1: Black center screen / mcu failure caused by a faulty navigation MicroSD card

    If you ever played with LEGO you can take the Model S dash apart. Seriously, it's simple. All the screws are identical except two which are a different color so easy to tell apart. No need to disconnect any cables from the MCU, just remove dash on both sides and tilt the MCU forward enough to...

    MCU1: Black center screen / mcu failure caused by a faulty navigation MicroSD card

    Out of curiosity I looked up environmental specs for SanDisk. From SanDisk cards environmental tolerance (waterproof, temperature, magnetic and x-ray proof). SanDisk has tested its SD, SDHC, microSD and microSDHC memory cards under a variety of tough conditions. Our standard, SanDisk Ultra...

    MCU1: Black center screen / mcu failure caused by a faulty navigation MicroSD card

    I considered the SanDisk extreme but don't think it makes a difference as the ultra is also rated for high/low temperatures. The only real difference I saw was the extreme is "gopro approved". I reckon gopro charged plenty for that endorsement explaining the higher price. As for high endurance...

    MCU1: Black center screen / mcu failure caused by a faulty navigation MicroSD card

    Working! Turns out I had to leave the car over night and this morning nav works again and it shows I'm using 2021 maps. So to summarize what I did: Symptoms: Nav worked using 2020 maps. It showed 2021 maps available for update but they failed to download. Progress bar never moved even after...

    MCU1: Black center screen / mcu failure caused by a faulty navigation MicroSD card

    Took an hour but ddrescue managed to read both partitions 100%. I'll image them to the new MicroSD tomorrow morning. Unfortunately I got cocky when it started downloading the maps and put everything back together so now I get to take it apart again.

    MCU1: Black center screen / mcu failure caused by a faulty navigation MicroSD card

    I had the MicroSD fail on my 2013 P85+. Old maps (2020) still worked but it was unable to update to 2021 maps. I got a new 32 GB MicroSD and partitioned with LuckyLuke's script. After installing the new card in the MCU it started downloading. Once the progress bar showed 100% I got a message...

    Fixed: Loose rear end (pulls right accelerating, left on regen)

    Just realized it's been over 2 years since I posted this so thought it was time for an update. I recently replaced tires and happy to report they all wore evenly. No inner edge wear indicating toe issues. The car also still drives perfectly, no sway or pull or other funny business when...

    MCU1 Recall Will Happen Very Soon?

    Nope. I tried booking an appointment in April and they cancelled it due to "lack of parts" and said they'd contact owners when parts are available.

    Can't Complete Wi-fi Downloads 2012 Model S

    I had a similar problem last month on my 2013 with original MCU1. Nav would get stuck on initializing navigation and after a reboot it would say it needed new maps. It would start downloading but get stuck. What fixed it for me was to do the "harder reboot" (or whatever it's called) where you...

    Checked Alignment: The Good, The Bad, The Ugly

    Cross camber isn't ideal, if it were mine I'd set the passenger side to -1.5 also. But to get it to stop pulling you will probably have to adjust caster. Increasing the passenger side caster and/or decreasing driver side will make it stop pulling to the right. The toe values on the Hunter are...

    Fixed: Loose rear end (pulls right accelerating, left on regen)

    I don't have a lift so I did it on jack stands. I cut the bolt with a dremel since there wasn't enough room for my angle grinder. Someone else on here used a sawzall which I think is probably a better choice (faster).

    Reliability of older Model S?

    I've owned a July-2013 P85+ since January 2014 (ex-demo car). Warranty expired 2018 as I didn't get the extended warranty. It's low mileage, I only have 34K on it. Since then my repairs have been: Update rear toe links to new design to fix loose feeling in rear suspension. Parts cost $200...

    Warning for Emmc

    My understanding of how it works: eMMCs, not just Tesla but eMMC in general, have extra unused capacity that you don't see when you ask the eMMC for free space. The eMMC also has a little controller that manages it. The controller is part of the eMMC. When a memory block goes bad the controller...

    Suspension link install

    That looks like it would work much faster than my dremel. It took me a good 20-30 minutes to cut it with the dremel.

    Suspension link install

    There's very little room to work so you need a Dremel with a cutoff wheel. I tried a couple angle grinders but they were just too big to get to the bolt.

    Tesla now repairing MCU1 with a new Tegra card for less than $500

    My Tegra replacement is quickly becoming a fiasco. Booked preventive replacement of Tegra board 8/14. Tegra ordered 8/16. Service appointment pushed multiple times as they couldn't get a board until 9/9. Dropped the car off yesterday 9/9 which was a bad experience in itself (no response to...

    Near annual replacement of 12V battery is typical according to Tesla Service Tech

    Both the C&D as well as the Atlas are AGM. I don't think the original Excide was so that would explain the config change once you replaced Exide with C&D. Why a config change is needed for the Atlas I don't know.

    Tesla now repairing MCU1 with a new Tegra card for less than $500

    No kidding. You might want to pick the car up until they have the part. My Tegra board was ordered August 16th and still hasn't arrived. Currently scheduled for September 9th but that's only if they can get the Tegra by then.

    Near annual replacement of 12V battery is typical according to Tesla Service Tech

    If you need to change the config depends on what is in there now and what you can get for a replacement. Most likely your car is currently set to "C&D" as that's what the MS used for many years. Really early on they had (I think) Exide batteries but those went away in 2014 or so. However, I've...
