Technical

Hello there. I wanted to know if there were any technicians on this forum. I have been working on Teslas for about six months and certified for structural repairs. Sometimes I run into things that I have to figure out on my own. And would want to share with other technicians.

First, we would just like to say hello to the TMC community! I’m Joe from Skyline, and we design, develop, and make aftermarket accessories for Tesla vehicles. We are excited to become more involved with the TMC community, and hope you enjoy checking out some of the cool stuff we are working...

There are some wrecked Roadster sports for sale now and then. I wonder how many parts that need to be moved to make my Roadster into a Roadster Sport. Motor, PEM and some suspension parts. Is that all?

Hey guys! What will happen if I join LED restyling headlights from 2017 Tesla Model S to my 2015 ones??Who knows? Is it working?

Roadster 1038 arrived last week and all has been well. When I returned from work and plugged in the usual fan noise from the back started but this time there is a ticking sound that is superimposed. The noise seems louder from the undersurface at the back and I assumed that the fans that cool...

Hi All, My name is Shawn, I live in Southwest Michigan. My car is a 2010 Fusion Red Roaster Sport #785 delivered December 2009. I replaced the VMS and ESS in 2015. The car was plugged in to a mobile connector 14-50 240 volts with good voltage and no breaker tripped. Across the winter I...

So, I'm in a unique situation right now that I would appreciate your feedback on. And of course, time is of the essence here. I just purchased a 2015 P85D from the original owner. So far the transaction has gone pretty smooth in regards to the vehicle being shipped on schedule, and clean...

My new article: New Research May Vindicate Tesla's Choice To Forego LIDAR. Summary: New research finds that a self-driving car can use cameras to determine distances to within 10 centimeters (3.9 inches) of accuracy. 10 cm of accuracy is most likely sufficient for self driving, making LIDAR...

Is it really not possible to adjust the camber in the rear on a non sport Roadster. My tires are wearing on the inside and the garage said that there were no place to adjust it. Is it possible to adjust on the Roadster Sport?

Quiz time! Fact 1: Ontario requires you to apply for your charger rebate within 3 months of installation. Fact 2: You can apply for your charger rebate only after you have received your ev rebate. Fact 3: it is taking about 6 months to receive your ev rebate. For example: install charger on...

Hey Club, Patiently awaiting my Model 3 and have been looking into home charging stuff. I want to install a NEMA 14-50 outlet in the garage now and just use the included UMC when I get the 3. The UMC will stay plugged in to this outlet most of the time (save for maybe 3 or 4 roadtrips a year)...

Is there a resource that shares the gear ratio of each motor on the dual motor Model S? I'm wondering if the front motor has a longer ratio. I believe if it did it would help with high end speed and efficiency/range.

Can the HVAC be scheduled to start at a particular time on certain days? My schedule is irregular and smart air preconditioning is not ideal option for me. Looking for an option that would not require to log into the app every time.

Does anyone know where the sunroof control module is on a 14 Model S? I have checked the fuse and it is good. I called Tesla Tech support and they walked me through waking and reboots and still no response. The controls do their thing but nothing happens. The PO had a roof rack on the car and...

How does one change the memorized charge amp car location? I just changed out my GEWATTS 40amp charger to the latest Tesla unit. Question , i have the requirements for the 48amp charge and it will not change the setting. Dip switches correctly set at dial at the #9 spot, correct 6 wire and 60amp...

I couldn’t find a previous post about this: Looks like the SiriKit intents for lock/unlock, battery level, visual and audible indicators were added to the Tesla iOS app at some point. None of the release notes mention it. Details if interested Car Commands | Apple Developer Documentation

Tesla’s safety leadership, this time in panoramic sunroof design, has again been proven. The Model S panoramic roof has always been made of Lamisafe, a windshield-grade laminated glass, while other makers have equipped their panoramic roofs with tempered glass—a cheaper but hazardous...

Hello, I finally am a proud owner of a pre-owned P85 red with Pano and Tech. I love the car. I just got connected with the Tesla app and it loads great on my phone. One issue I have, prior to delivery the PO reset all the settings back to factory. Since then the car tried to update twice and...

I purchased a salvaged Tesla Model S to repair in my garage. I'm new to this, so I'm in the "information gathering" phase attempting to learn as much as possible about the car and other people's experience in hope of building technical intuition to guide me through all the troubleshooting issues...

Hey all - I have a Model X with the towing package and it's giving me some trouble. I have a little 4x8 utility trailer that I use once in a while to run for some lumber or whatever, but for the third time now, after going for a drive with it connected, trailer mode won't shut off when I...

One source says it’s a u-blox NEO-M8L, but I’m looking for confirmation on that.

I have read too many posts now about having to drop the car back at the dealership after delivery due to some imperfections/issues (either minor or major) found during the first few days of ownership that need fixed. It kind of makes me a bit paranoid now that whenever I take delivery of my car...

I put this together for something I was doing for myself and thought I'd share it. I know there are other Tesla PowerShell modules out there but I didn't come across one that has been updated since some of the API changes (thinking sunroof). GitHub - andylyonette/TeslaPSModule: Interact with...

Okay yes, technically we got an update with the Camper mode release, but seriously. I was TOLD self driving woulda been here months ago, AP2 wouldn’t be AP0.5 anymore, and general patterns show we get updates in mid September/ October. Well I hate to be the one to bitch about it, but we have...

Wow, to coin a phrase what the heck are they thinking.... New bill could let companies retaliate against hackers

Here is my take on the installation of the dual channel dash camera system in Model S: BlackVue DR750S-2CH installation in 2017 Tesla Model S I managed to install the rear camera without removing the large piece of trim from the tailgate, so if that was a show stopper for some, hope you will...

I seem to remember having a glove box light but there isn't one working now. Inspecting the interior, I find a very small apparently LED light on the upper outer rim—but I don't see an easy way to replace it. Is this an end user replaceable bulb? If so, where do I get replacement and how do I...

Hello there I'll have to get my roadster windshield changed in about 2 weeks. For different reasons of insurrances and nearest Service Center being far, I'll have the job done by a local repair shop. The replacement windshield is already on its way (a lotus Elise one), no problem there...

Wondering if there was a simple fix for this, or whether I'm going to have to take it back in. Our Model X had its charge port door adjusted, as it wasn't closing completely. I've just noticed the left-side brake light and turn signal aren't working, and I'm not getting a fault notification...

There is a clear new trend among automotive companies. They are now innovating again. Tesla is a big driving force in this industry. While I wouldn't say they are "disrupting" the entrenched players, their pace of innovation and acceptance of risk while innovating is certainly pushing big...

Audi e-tron Quattro and Sportback: New Tech Details on the Tesla Model X Rival Interesting that Audi is claiming development of a current-excited synchronous motor for its new EV. As opposed to an induction motor, current must be supplied to the rotor windings on this type of motor -- perhaps...

I'm just wondering if anyone has clues or history what this could be before I hear back from the SC. I figure it has to be something 'general' (like a overall sensor board, is there such a thing?) because of the nature of the beast. Last night as I was calling Customer Support about the...

Hello, i have a clean title tesla S and i have a salvaged tesla S, I've been buying parts for my salvaged with my clean title. i got it all working and now i cannot charge it a t home anymore, I've done all i know and its a no go....sooooo, i m looking for a tesla mechanic that i can take it to...

A few years ago, someone posted the internal resistor values of the UMC charging adapters that tell the UMC how much current to draw. I searched all over but cannot find the post now. Anyone have this info? Thanks!

I had a busted UMC lying around that I salvaged the cord from for another project. Left with a useless UMC box, I decided to open it up and take a look around. This particular UMC met its demise by having the cord forcibly pulled out of the UMC box while actively charging. The metal and...

When I was in to the Service Center in Dedham, MA I noticed a Statistics TV that was “live” streaming statistics from around the world. It included a few things like the most used supercharger station today, how much CO2 saved total, and how many cars produced. I can’t seem to find a website...

This week The Economist published an article about electric motors: https://www.economist.com/news/science-and-technology/21728888-better-motors-go-better-batteries-electric-motors-improve-more-things The article isn't deeply technical: no equations. But I found it worth reading.

Hello to all ~ Irma hit hard, but thankfully spared us from total disaster. My home is still standing and no water got into it. I am not at my residence and probably won't be able to get in for maybe as long as a week (or two.) There is no power as of right now, and no word on when it will...

Hello everyone, I was recently thinking about real longrange trucks with swappeble batteries and I was wondering how high the voltage of such a truck battery and swap battery should be. I think it should be significantly higher as a car battery because otherwise the cables would be too thick and...

Can this be done on a Tesla with air suspension?

My roadster joins me in disapproving of this weekend's weather - attempt to turn on AC and < 1 minute the car throws up a 'power train needs service' warning and needs to be pulled over, turned off and on again to continue I'm looking to get an appointment at the SC but curious if others have...

i have a 2016 model s thats an unsupported vehicle as its a damaged repaired vehicle so tesla garage will not look at it. so the problem i have is as follow. some times probably 50% of the time i key on the brake pedal when you touch is violently pulsing and bangs. i guess the brake assist is...

Damien has been doing some interesting work dissecting and controlling Tesla drive units. Here is his latest video working on the front motor inverter:

I’m looking at buying a slavage Tesla that needs a couple new door panels. Wanted to find someone who has some experiance and a reputation. I want to know breakdown of the parts and labor. Live in zip 26034. Please note that I’m pricing out many people, so make your bids accordingly...

Background: Talented amateur electrician, not afraid to add/remove breakers, run new circuits, etc. Started looking into adding a 14-50 outlet to my garage. Phoenix will start cooling down in the near future to where that kind of work will be possible. My problem? A full breaker panel. I...

Does anybody know who can troubleshoot the car? I have a p85. Last week a software upade came in like usual. I started it and i guess in the middle of it it failed. When i got back in the car now it gives me whole bunch of issues. Software update needed, car wont charge, car also wont start...
