I need remote help to manually flash a Drive Inverter logic board. Willing to compensate. The inverter's logic board is from a P85 so announces hwid 13. However car is P90D insane so it fails to redeploy because there isn't a DI firmware under /deploy/seed_artifacts that is di:13 and 4wd=1 at...

Quite the contrary they're increasing if you look carefully. They're just so low you actually need to do the math to notice.

Thank you for the explanation. I also saw this board and its github page while researching how to solve this. Yet where I am located it is not easy to print circuit boards nor it is easy to have them shipped out. So to accelerate the process I just taped wires on a long wooden stick used to...

I have a list of battery pack part numbers but part number you gave is not in the list. Probably a 2020 built one. Does it say REMAN as in remanufactured? Please keep us posted. As a fellow facelift 2017 90D owner I'm facing more degradation than expected and am curious why you're getting a...

The fact that they would be almost super healthy if multiplied by 100 is super suspicious. I also don't know if they would discharge so evenly below 1V level. Also having e-mails back and forth with Gruber at this point. I did measure with a simple multimeter set to measure 20VDC. Readings would...

Bad news. ESS is absolutely dead. @markwj and @ML Auto was right. I don't think this is recoverable. I don't have a lot of experience with batteries but these voltages are absolutely bricked right? I wish Roadster ESS was like the Model S i.e. contactors absolutely open in case of fault. Either...

thank you for the response. Connector I’m referring to is the mid to back harness on the right side of the car. A circular connector going in from A pillar bottom right hand side to rear. I will check sheet voltages today and let you guys know. The design being different than Model S is bad...

I will but I've seen Model S packs when left isolated (i.e. contactors open all the time) don't have such self discharger to brick them. So still hopeful. When you consider it was 78% SoC when dead so around 3.9V-4V per cell I want to believe there is hope. If not I can always revive it. Let's...

Thanks for the swift response. I'll check the inside of the 400V controller first thing in the morning. Is it true that if fuse in it is fried then fuse inside ESS is also fried? Hopefully changing fuses in both fixes it. If not hopefully I can find a spare 400V controller. Still worth checking...

Hey folks; Long story short I have the only Roadster left in our country. 2010 model year EU VIN278 around 60k miles. It has not worked snce the owner washed the car in May 2018, had a little drive and parked the vehicle. Thankfully Gruber has been helping me for the past 4-5 months over...

Hey; Living in Turkey, your average Tesla ownership experience is quite alone. It was, at least until we started out a 3rd party repair service in our market as the Tesla owner's club of the country.(E-Garaj/TeslaTurk) I am driving a 2017 Model S 90D built in March. After just 420 cycles or so...

Nope

After changing the hvilnodes count, HVIL errors are gone actually but I'm getting; -HVJB disconnected -HVJB over temperature (two different ones) -FC contactors welded (all kinds of different errors) I'm still thinking this means HVJB logic connector is bad. However I checked the voltages...

Update. Found out that I need to lower hvilnodes on gw config to 4. Also didn’t work. So the 2nd A-Ha moment that didn’t work. I wonder if it is the HVIL that is causing this there may be a damage in hvjb reed switches or something but errors are HVJB over temperature and FC contactors welded...

How would someone get rid of vital errors about HVJB, FC contactors and HVIL? Hence the BMS fault that comes with it. I was removing the broken master charger from a dual charger 2015 Model S to instead make slave the master and lower config to single charger. Steps; - Removed slave charger. -...

'17 90D, 73k miles, average consumption is 344Wh/mi. Quite high compared to Raven. I don't drive in a performance oriented manner either. On the contrary actually I would consider myself an efficient driver. I wonder if it all boils down to the Raven motors or if there's more to it.

I need help to use somebody’s compatible toolbox for a specific panel. Here’s what happened. Vehicle was suffering from f027_BMS_Drive_iso_Repeated. I followed the bulletin to measure insulation resistances of hv parts. Drive unit measurements were out of spec so drive unit was removed. Indeed...

thank you for the reply. However it didn’t have this problem before I opened up the inverter and motor. I opened it up to clean the goo inside since the front motor “did” work but would go into limp mode thinking there was low coolant flow. Indeed I found a temp sensor covered with goo and...

Is it not possible it didn't get behind the motor? Maybe the car was in parallel mode when the accident happened and it saved it damaging only the front motor? I want to argue this because I didn't find any goo on the rapid connector of the battery. Nor there are any coolant flow errors about...

I'm working on a car that had front impact damage that pierced the radiator. Random technician thought it would be a good idea to put in hardening liquid goo to stop the leaks from happening. It did stop the leaks but disabled the front motor. (P85D) So after I checked the coolant tubes going...

67k miles update. Very little DC charging. Roughly 1,500kWh DC / 24,000kWh AC charging. Those DC charges are not Supercharger, mostly CCS or ChaDeMo so 75kW or 48kW. (Because I'm living in no Superchargers zone) EU car, so typical range displayed at 100% is 411km. That equates to 77kWh Nominal...

Wow you mean to tell me there is no /var/etc/saccess ? as for #2 I thought this was the easiest. I’ll try and do that with a friend’s MCU2 first and if I can reach gw I’ll pull the plug on purchasing the parts. I’ll have to lookup easy jtag’ing the intel atom board. I figured this would be...

I finally found the parts from a wrecked car and thinking of attempting this retrofit myself. Not only because it will be cheaper to do than Tesla's own but because I'll keep radio and I'll learn a lot while doing it. I'm thinking of rooting it via desoldering and dumping data from emmc and...

Today after changing the coolant with a Model S (using the fluid drain/refill on toolbox so I’m sure it was on series mode while doing the drain and refill later on) I got the limp mode for front motor. Reason being announced on basic-alerts; low flow. I kept purging the air out of the system...

They're balanced the most when; a) They're on higher SoC b) They have no load on them, potentially even when contactors are open. Even AC's 2-3kW of load would create a minor imbalance momentarily. Overall you don't have to worry at all about Tesla's pack management as far as cell voltage...

I meant 2020. :) Sorry about that

I think both are normal. Imbalance depends on the current load and SoC. Lower the SoC more imbalance there will be. (the case in your screenshots)

No reports in EU yet. My service center contact said they'd get some demo units maybe to teach the technicians soon but no scheduling yet. Their guess is fall 2021 earliest.

Might be a dumb suggestion but did you check the grounding bolts?

For Voice command to work all of your friends/family names should be in English. Obviously doesn't recognize my Turkish friends and family names. 3rd party apps require the browser to work. Which is quite rare with MCU1.

I know it will be ignored because they don't develop for Model S/X anymore but having the option to search through contacts on the phone app would be great. Also When selecting a contact from IC, I want to be able to not only select the first letter but I want to type with letters and narrow the...

Hey all. I need help downgrading a firmware. It is a Model S with AP2.0. It needs to be downgraded because while the rest of the car was on 2018.48(v9), dead emmc CID is revived as 2020.20(v10.2) Because of the difference the rest of the car doesn't update. They stage but APE ends up with a...

How about the CAN values on S/X?

My 90D on 19" is 344Wh/mi (214Wh/km) on average over 60k miles. I don't drive aggressively nor like a grandma. Nowadays due to climate last 1 month's average is 310Wh/mi, in winter it is closer to 400. (My area's temperatures range from 30F to 95F between winter and summer)

@wk057 for those of us with root access, could you elaborate where you see the more accurate numbers in the bms? Is it the BMS section of the Basics tab? or do you get shell access into the gateway and debug bms there somehow?

As an owner of the same config still on the fence whether it is worth the money, mind sharing your experience pre/post upgrade? My car is a little over 3 years old and already over 60k miles.

Most technicians unfortunately lack the linux knowledge required to actually service/repair/restore Tesla's software. Instead they have UI versions like Toolbox, which technicians rely on. In new cases like the MCU2 retrofit, if the UI technician is as I've described, they might not even know...

One more question about this @rooter Will abandoning VPN cause MCU1 self repairers to keep connection to the mothership even without saving openvpn keys from partition 3? (/etc)

Even with MCU1 they're still cracking down... Some poor 8.1 driver unbeknownst to all of this somewhere will need a part change sometime, will change it themselves only to find themselves or any 'hacker' helper unable to redeploy. IT is quickly turning into Apple vs. jailbreaks.

Thanks as always rooter. I wish I had more linux skills. What I meant was will rooted users on V9-10 lose their ability to do anything because of this change of connection to mothership? If I remember correctly redeploying on AP2+ you couldn't get APE files from the mothership and had to push...

I can't believe they actually did this. Maybe there really are only a handful left in v8.1(many of which are here in that case) so they bit the bullet. Will this affect how work is done in cars that are v9 and above? Can someone who knows Tesla's software elaborate on what this change actually...

No, new cars come with AM/FM. However with the retrofit, the new MCU uses a digital tuner whereas MCU1 cars had the analog tuner. Tesla doesn't want to do the extra labor to switch out tuners with the retrofit because they're really in a tight space hard to reach. That's the reason why only...

We didn't see any retrofits done at EU service centers right? Not even APE2.5 MCU1 cars. My (Graz) Service center gives me vague replies about timing still. AND I'm AP2.0. So maybe I can 'pay' to get mine in 2021?

The way geofencing works is, once you change a suspension setting for 'high' or 'very high' at any point, car automatically "geofences" that location. If only you press the X that appears when you tap high or very high, only then it doesn't geofence. So it is sort of like an opt-out system for...

There is that problem for sure. However please check next time whether your suspension setting is on something other than standart while accelerating. I was complaining about the same issue and getting the same answers. Then realized I had too many geo-fences for auto raise suspension and when...

Could you give me tip on how to get MCU2 to factory mode? I connected through .103 (obviously there's no .101 like before) It does get into developer mode and I can activate diagnostics mode. However even if I do Reset All Data from Factory tab or GUIfactorymode=true it doesn't work. With reset...

UI still doesn’t show Plovdiv. I don’t know if an update is necessary to see new Superchargers pop up in the map, or if it appears automatically without an update. I’ve never had a Supercharger opened close to me. Exciting!!

Yeah definitely portable Superchargers until they build the real ones.

Great find but this kind of looks like the portable Superchargers. They take these to unveilings or events. In this case they probably want to open the Balkan corridor but can't wait for Belgrade to finish. I believe Plovdiv and Nis are ready but they want the whole network to connect so between...

Is MCU2 gateway same as MCU1 FreeRtos gateway? If so I believe it would be almost equally easy to change mcu2 config as one would not need root. (Which is notoriously difficult to achieve with mcu2) Right?
