    Aircon keep vs. letting car heat up and cool down

    I finally got around to running a somewhat representative test of energy consumption for the aircon in my 2020 Model S (Raven). Note it does not have the heatpump like all newer models do so is significantly less efficient. Inside set temperature is 21C for all three tests, outside temp 30C for...

    Trunk/boot no longer closing or opening.

    2020 Model S, 6 months out of warranty sadly. Closed trunk (empty, no obstacles), did the beep, and got stuck in open position but unable to pull open. Manual release not working either. So much for Tesla's understanding of an emergency release... Seems to be a fairly common problem?

    Anyone know where to get a dual-bus diagnostic port to CAN adapter cable for a 2020 Model S?

    I used to have this cable made by Maxwell Autotech: Tesla CAN Diagnostic Cable (Sept 2015 and up) – Crimped OBD-II – Maxwell Automotive Technologies Unfortunately the cable has been pulled to shreds, with probable damage to the connectors inside the plugs as well, as simply soldering the ribbon...

    Particulate air quality inside the cabin measurement

    For some time now I've been wondering how well the HEPA filter works. I just answered that question by placing a PurpleAir sensor measuring PM1.0, PM2.5, and PM10 behind the driver seat for a few days and running some test. The measurements are done using the US EPA Air Quality Index (AQI)...

    USB and 12V power switching logic

    Does anyone understand how the USB ports and the 12V socket in the console are switched in a 2020 Model S? Specifically: - How long until they turn off when the car is locked? - Is that timeout configurable? - Does camp mode or climate keep mode keep them powered? Would be nice to be able to...

    Supercharger suggestions

    I keep wondering why Tesla doesn't make recommendations on arrival at a SC on which bay to use. Or better yet, give a list for each bay and show the current charge rate of any vehicles present along with estimated time for completion (or SOC of the car). That would make it so much easier to...

    Spotify interface question

    Given this screenshot, how can I get to the album containing the track that is currently playing? Doesn't seem like an overly exuberant request, yet am unable to find a way there other than manually searching for the album title, tapping "Albums", and hoping to find it in the resulting list...

    Tesla refusing to invoice insurance company for repair

    Just had a cracked windscreen repaired by Tesla today and the insurance company gave me a repair authority form to give to Tesla so they can pay them directly without me playing bank. Tesla Alexandria flat out refused to deal with that, claiming they, as a company, don't do that. Customer pays...

    Three out of four 21" turbine rims cracked within a couple of months

    2 year old, first and only owner, 60'000 km 2020 Raven with 21" turbine wheels. Within a few weeks of each other, front right and rear left rims had slow leaks caused by cracks. This happened in March 2022. Tesla laughed me out of the shop when I suggested that smells of manufacturing defect...

    My own car on the dash screen is suddenly shiny white without aliasing

    This morning my car icon/depiction in the dash suddenly turned all white and with jagged un-aliased lines/edges. Rebooted the MCU and it came back the same way - any clue what's going on here?

    Why does the battery discharge while plugged in?

    With charge target set to 80%, my car while plugged into the wall at home goes through several discharge to 78% then charge back to 80% cycles a day. Is there a smart reason it is doing that, or is that a BMS planning oversight? I would have thought that minimising any charge cycles while...

    Powerwall app access question

    Hi all, I'm considering putting in a PV+powerwall system in our family holiday home. Is it possible to register multiple accounts to display/manage a single powerwall? I don't want extended family have access to my car either... but I do want them to be able to manage and view the powerwall...

    Has anyone taken their Tesla onto the Sydney Motor Sport Park / Eastern Creek for a race day/night?

    As per the title - I'm taking my 2020 Model S Performance to a race night there soon, was wondering if anyone here has done that before and has any hints/tips? There appears to be a destination charger on the site. 22kW isn't gonna charge a whole lot unfortunately, but better than nothing for...

    Video and data blackbox for my Model S

    Hi all, I've finally finished building the framework to automatically make blackbox videos using the dashcams in my S with data overlays recorded on every drive using my phone and a CAN bus adapter. Check out a sample drive here: Read the video description for more details on what it...

    Pushing range: How far can you really go?

    I went for a long test drive last night and broke the Model S distance record on Teslafi by clocking up 658km / 409mi in just over 9 hours: TeslaFi.com Shared Drive The purpose of this experiment was to figure out how far I could push the range by going at an "ultra long range cruise speed"...

    Demystifying the power consumers in my Model S

    I've been using a BT CAN bus adapter and the tesLAX app with some custom signals I've developed to shed some light on the various subsystem's energy consumption. Here's what I've found so far for my 2020 Model S Performance ("Raven"). The base energy consumption sitting in the car with gear in...

    Autopilot energy consumption - an interesting observation

    I often drive in the country where there are distances large enough between chargers that it pays to actually figure out power consumption of all the consumers so as to avoid unnecessary stops or make it last that extra dozen km's for comfort. Using a CAN bus adapter I've been looking at how...

    Spiff just died a black screen death...

    Came down to the parking to drive to work, the car wouldn't summon out of the parking as it does every normal day, but it locked and unlocked. Squeezed myself inside and stepped on the brake pedal. Both cabin and headlights came on, but no displays, all black. Tried an MCU reboot, nothing. I...

    Actual cost of supercharging?

    I took advantage of the free unlimited super charging for life offer when I ordered my S in November last year. I'd be interested to know what Tesla are charging those customers who don't have that option. Can anyone shed some light on this? Model 3 or S info welcome.

    Autopilot rocks video. With some issues and improvement suggestions.

    I finally got around to take some videos while driving and collating the recurrent issues I seem to have in my 2020 Model S Performance. Some food for thought at Tesla!

    Car not going to sleep

    I'm at a loss why it won't go to sleep. Brand new 2020 Model S Performance, owned it for about a month now, and it just won't go to sleep - or so TeslaFi tells me. I've configured TeslaFi correctly (I think) to let it go to sleep (hence the messages that it doesn't go to sleep) - I have no other...

    How many rims scraped at Broadway charger exit?

    So I just devirginised my wonderful 21" turbine rims, front left, scraped at the bloody tight exit at the (criminally narrow) Broadway charger. Made the approach at a shallower angle than usual today, which should be easier to navigate or so I thought. Never scraped a rim on any of my cars in...

    MCU screen customisation: shortcut buttons, music/media window...

    I live in a warm climate environment where seat heaters are all but useless (and I would have loved to receive ventilated seats!). Has anyone discovered a way to replace those buttons with other functions I frequently access, such as the energy monitor? I also find the music/media window...

    logging data from the car?

    Has anyone managed to obtain a running log from the car somehow, a list of GPS positions, speed, AP modes engaged etc.?

    Some autopilot issues

    3 weeks since I got my 2020 Model S Performance and already 4500km on the clock, two drives Sydney Melbourne and some local driving did that. Very happy with the general stability of the autosteer, drove me to Melbourne and back from Sydney essentially on its own. However... (note this post is...

    cruise control unavailable

    Went to run some errands just now and was unable to engage the autopilot. error message says "cruise control unavailable", pressing the exclamation mark on the main screen next to the driver name says "Dl_u015: cruise control unavailable". No car surrounds are shown on the screen (no traffic...

    Speed limit detection problems

    Hi all, I've driven about 2500km now, most of it with autopilot engaged and encountered several issues chiefly to do with speed limit detection. It appears that my brand new 2020 Model S Performance simply does not read speed limits from camera input. I've driven through a dozen roadworks zones...

    My 2020 Model S has arrived

    So after a three month and 10 day wait, my Model S Performance w/Ludicrous has come home. I don't get emotional much about technology, but driving from Sydney to Melbourne on autopilot the day I picked it up (Thank you delivery team for turning things on their head to make this happen!) I did...

    Model S Performance with Ludicrous insurance

    Hi all, still trying to find reasonable insurance for my very soon (~March 9th) to be delivered Model S Performance with Ludicrous. The best (well, the only offer) I could find was through a broker with agreed value of $202320 (the purchase price) and will cost an exorbitant $4200 a year. NRMA...

    NRMA and QLD chargers with a 2019 Model S

    Hi all, NSW and VIC seem to be well enough covered with Tesla's own chargers. But QLD seems not so much - so I'm trying to make sense of which adapters I should buy to be able to move freely throughout QLD with my (soon to be delivered) 2019 Model S. Some of the posts here have me confused on...

    Preventing 1h rollover buffer for dashcam

    The manual says dashcam footage is overwritten with a rolling buffer of 1h length. For those of us living in parts of the world where traffic rules are enforced with cameras this seems inadequate. A week or so after an alleged traffic offence, the fine arrives in the mail, and more often than...
