We've obviously seen the claude remaps. Wondering if anyone's doing anything else more interesting?

Anyone tried unlocking an ECU using AI?

Any other cool stuff you're doing?

EDIT: This is a reminder, please do humanity a favor, try to give back by open sourcing anything you can.

There is a currently unpatched exploit in HKMG android based head units that allows persistent root code execution and ADB access which has allowed for some wild stuff including enabling wireless CarPlay, integrating 3rd party GPS app navigation directions into the stock HUD, and kexecuting entirely different OSes with working volume control and cellular data! These pics are shared with permission of the Discord OP that got this running.

I'm investigating whether it's possible to permanently disable all wireless communications on a 2026 Toyota Corolla Hybrid (Australian model) without affecting essential vehicle functionality.

I haven't purchased a new vehicle in approximately 18 years, and I'm genuinely surprised by how much the automotive industry has changed regarding connectivity, telemetry, and data collection.

I work in IT and cybersecurity, and I'm concerned about the privacy and security implications of modern connected vehicles, particularly persistent 4G connectivity, location tracking, and remote access capabilities.

With rapid advances in AI, large-scale data collection and increasingly sophisticated analysis techniques, these concerns are becoming even more significant to me.

My goal is to physically prevent the vehicle from transmitting data or communicating with external networks. Software opt-outs and privacy settings are not sufficient.

I'm willing to sacrifice connected services, SOS functionality, and OTA updates, provided essential vehicle functions remain unaffected.

Questions for Toyota technicians, automotive electronics engineers, or anyone with relevant experience:

1. Can the DCM/4G modem be physically disconnected or removed without affecting essential vehicle systems?
2. Are there other independent wireless modules capable of transmitting telemetry or location data?
3. Would removing the DCM fuse be sufficient, or is complete hardware disconnection necessary?
4. Could these modifications affect internal systems, infotainment, diagnostics, driver-assistance features, or normal vehicle operation?
5. Warranty: Could these modifications affect the warranty on a brand-new Toyota, particularly under Australian Consumer Law?
6. Is there a reversible, non-destructive hardware solution that minimises potential warranty issues?
7. How can I independently verify that no wireless telemetry is being transmitted?
8. Has anyone successfully done this on a recent Toyota, particularly a 2025–2026 Australian Corolla Hybrid?

I'm specifically interested in hardware-level solutions, technical documentation, and firsthand experiences, rather than software privacy controls.

I'm not looking to debate whether these concerns are justified. I'd simply like to understand what's technically possible and what the consequences might be.

Any technical insights would be greatly appreciated.

I just wanted to say, ive had enough of this hobby lwok. it’s expensive and exhausting. I had a fully working dash and now its all fried. sorry not sorry.

It seems like everyone wants to keep their secrets. Too many YouTube videos leave out the important parts out on purpose to protect their, "trade secrets". Is there any shared resources or are we making everyone learn everything from scratch on their own?

I know I get it, you couldn't charge $300 dollars for ten minutes work if everyone knew how to do an immobilizer delete, but come on I wanna learn and I can't find any tutorials. Its crazy. Every other hobby on the Internet is trying to share the skills, but I guess this hobby is different?

Does anyone know what the developer password is for 12.1 Inch Android 12 Car Radio for Nissan 350Z?

I would like to get into this hobby. Are there any cars/brands/years that are good to learn on? I'm guessing things like an easy to acquire ECU that I can have as a backup. Are there any cars to avoid as a beginner?

Can someone with a working Mercedes Xentry activation generator get me a code please? My laptop is set to February 2008. I can’t get mine to generate a valid license code.

​Hey everyone,

​I'm currently developing a management app for auto repair shops and looking to integrate direct OBD-II functionality. My end goal is to provide diagnostic and bidirectional control features similar to what tools like Launch or Autel offer.

​I'd appreciate some guidance from the community on a few points:

​Reverse Engineering OEM ECU Protocols: Where do developers typically source data, CAN bus logs, or protocol documentation for OEM-specific diagnostics (beyond basic OBD-II PIDs)? Are there open-source projects, databases, or specific forums dedicated to reversing proprietary manufacturer commands (UDS/ISO 14229, factory PID lists, bidirectional controls)?

​Wiring Diagrams & Repair Manuals: Is there any viable way to access repair manuals, DTC troubleshooting steps, or wiring diagrams via free/open APIs, or is paying for commercial enterprise APIs (like AutoData, AllData, or Mitchell1) the only reliable route for commercial shop integration?

​If anyone here has experience building diagnostic software or integrating CAN/UDS hardware into a custom platform, I’d love to hear your insights or recommendations on where to start.

​Thanks in advance!

I have looked everywhere, and i just cant find any diagrams for my car, its a Peugeot 206 1.9 XRD diesel 2001. Any help on where to search, i have downloaded some peugeot licensed apps made for mechanics, and couldn't find this car. Does anyone know where else to look, or does someone have wiring diagrams for my car and is generous enough to share them with me. Thanks in advance.

hello everybody...

where did you learn about ecu/module programming ad repairing? could you recommend an online training course or something like that?

hello, I'm a disabled person that repairs and flips clusters and has a very keen interest in cars and wanting to learn custom module program, EEPROM, ect. I use a lot of great open source tools for my projects like IPC hammer, or more the well known PCM hammer. I own vcxnano for my SPS2 subscription, tech2win, and it servers as my J2534 wrapper.

I'm very disappointed with SPS2 and will be needing other automotive softwares and other hacking. I've come across mhh auto in web searches but you have to be a member to grab files it appears. I'm aware it cost like 30 bucks to get a registration code and I'm not here to ask for one. I'm just curious how good it is and if anyone actually uses it? 30 bucks is a bit of an investment for me because I'm poor and 30 bucks gets me another junkyard cluster so I wanna be sure if its what it looks like.

We’ve had several cases where GPS/OBD trackers were located and unplugged pretty fast after vehicles were stolen. I’m trying to understand how they’re finding them so consistently.

Are thieves just checking the OBD port first thing? Using RF scanners? GPS jammers?

I’m also curious whether lower-power BLE-style trackers are actually harder to detect in practice, or if they’re just as easy to sweep for.

Would appreciate insight from anyone who’s looked at this from a security angle.

Hello, i have a q2 with an delphi mst2 mmi unit is there any way so that i can enable apple carplay on it. I have been told by some people that its not possible but some say that you can by some ethernet to usb coding

I’m working on a 2024 Audi SQ5 FY USA → EU conversion and I currently need online authorization for several protected control units.

I found a provider offering a 24-hour GRP/ODIS account for $100. They claim the account is created using my own email, I receive the full login credentials, can change the password, and don’t need them for OTP.

They also claim the access includes SFD1, SFD2-protected coding/adaptations and Component Protection functions without buying separate SFD/SFD2 tokens.

Has anyone here used this type of access before? Is this technically how current ODIS/GRP access can work, especially for MY2024 Audi with SFD2?

I’m mainly trying to verify what functionality I should realistically expect before paying.

Hey guys,

I'm looking to see if its possible to hack the stock head unit on a 2016 F56 MINI to write my own custom infotainment software (GUI, apps etc.).

I've considered a few options. Building a custom interface was one option with a raspberry PI that interfaces the LVDS screen, but it would be too expensive and probably over complicated, it would probably be cheaper and easier to buy an Android interface and mod that instead.

I looked into the PSDZData and pretty sure its running Linux/X Server, so this could be used for scripting, rendering to the screen etc. Claude has had a look at the files and found two methods to the shell, both by attaching a UART/USB-TTL adapter to the stock board.

1. U-Boot init=/bin/sh, no password needed, but would only work if the bootloader is interruptible. I doubt it is interruptible as everything is very locked down (assuming that bootdelay=0), but I may be wrong.
2. Serial login - COM Port 57600 baud. However, password is needed to enter the shell. Claude found the hash. Tried cracking with hashcat with digits/lowercase however both of these exhausted. I can't find the password anywhere online. It looks like if I have the password, that's the last thing needed to get shell access.

I have the password hash, I just need to decrypt.

Any help on this appreciated :)

Hello, I have a 2016 W222 S550. Ac and heat are not working, there is ‘Crash event detected’ fault noted in the ac module but no actual error codes or lights.

SRS module was professionally reset with no codes. Cant get AC module error cleared and none of my AC functions work. I have offline XENTRY and Monaco and I couldn’t find a clear crash data command for this fault. No help on the forums. Help is much appreciated!

I’m trying to get Apple CarPlay/Waze to project directly onto the Digital Dashboard (Active Info Display) of my 2018 VW Tiguan.

My head unit is a MIB2 Delphi with firmware train ⁠MST2_EU_VW_P0883D⁠. As you can see in the attached screenshot, multiple coding shops in Brazil are currently offering this exact software patch for Delphi units. Unfortunately, they refuse to sell the raw files or do remote sessions for customers in Europe.
Is there anyone in Europe or the Netherlands who offers this service? Alternatively, does anyone know where to find this patch? I work in IT, so flashing it myself via Telnet (D-Link) or an SD-card script is no problem if I just have the right files.

Any pointers to the right repositories or forums would be hugely appreciated!

I recently purchased a VXDIAG Nano OBD dongle to initialize a new ABS module on a 2013 Ford Explorer. Does anyone have experience with installing or running Ford IDS through VX Manager?
I've followed the instructions on the VX Manager website, but I'm stuck. When I click Run under the IDS section in VX Manager, it only opens a folder in Windows Explorer. I'm not sure how to install or launch IDS from there. And I don’t know if a subscription from Ford/Motocraft is required?
Any advice would be greatly appreciated.

Hi all,

I would like to know if I can activate App Connect on my MST2 device. I checked the FEC code list and it is not pat of the availeble codes. Is there still a way to activate it without buying new hardware?

Is there any alternatives to FDRS / IDS? I understand that there is Forscan, but I am after something more advanced like FDRS/IDS

Tried coding something on a newer VAG car and got "Access denied"?

Congrats, you've just met SFD (Schutz Fahrzeug Diagnose).

It's an additional security layer that requires authorization between the car and VW's servers. No token, no access. Simple as that.

I first ran into it on a Skoda Octavia IV when I just wanted to enable a couple of basic adaptations via OBD. Connected, entered the control module - denied. Took me a while to figure out it wasn't my tools or software. The module was just locked behind SFD.

SFD is used on cars from 2020 onwards - mainly MQB Evo (Golf 8, Octavia IV, Leon IV, Audi A3 8Y) and MEB platforms (ID.3, ID.4, Enyaq). It blocks adaptations, coding and parameterization.

Tokens are only issued through official accounts to registered users. So a regular enthusiast without dealer-level access simply can't get one.

Have you run into SFD yet? Which module blocked you?

Hi. Does anyone have account on mhhauto forum and could help me to contact few users from there? I would send you links to users and a message (containing my phone number) that I would love you to send them. Its about scam company that I wanted to sue and I saw there are more victims and those people lost money on this company too. Anyone willing to help? Thank you.
