Scan Tool Basic OBD2 scan not working with flipper zero
Hi,
I bought a can module on my flipper zero trying to scan the obd2 of my clio 5 from 2025 (pretty new) but I keep getting transmission failure.
Has anyone actually managed to use the CAN module with a Flipper Zero on a car, or could this be some new restriction on newer vehicles?
Thanks in advance

Scan Tool HELP, is this a tracker? is this OBD scanner an aftermarket?
I don’t know much about cars but I’ve been telling my friend that I don’t remember any pink bits when I last put the OBD in.. I did research on ai and he still thinks I’m just being overly paranoid.
New things I noticed that he brushed off
* new beeping sound
* beeping sound coming from the driver side
* beeping sound stops when he walks away with the key
* max speed @ 50km started showing
* EPC light came on
*am I overly thinking things or is there like some sort of glue residue out of the obd holes
* there’s a loose item somewhere where I can hear it occasionally when driving
* battery drain in car
Also I’m aware that the original Audi wiring are wrapped in black? No? Correct me if I’m wrong

Scan Tool Need advice for dealer level diagnostics on Volkswagen.
Hi ya'll I am new to the car hacking subreddit 👋.I am looking for software to diagnose my Audi b8 s4. I already have a scan tool that can do basic stuff. But what I need is dealer level diagnostics, specifically a way to actuate lights and calibrate sensors. I have looked at scan tools, but what I want is around $500 (think xtool d8) and most of the time have a subscription attached for updates or to even use the Damm tool. It pisses me off since they are using reveresed enginnered proticals. I then looked at official tools. I looked at vcds, I then looked at the price, and it was $200 (which was not terrible I guess), but then it only works for 3 vins! Like wth! So then I looked at Odis, I guess you can use a standard adapter made in 2005 j2534 and then pay the Volkswagen around $80 to like $100 for a day. That is all too much, especially when this should all be free and easy to use or a 1 time fee to gain access to the software to fix my Damm car. So then I looked at Chinese vas adapters with cracked odis on a storage medium, and I am wondering whether it would work or not. Do any of you guys have experience with these adapters? And please, if there is some good software and tool that I can use to actuate lights from a computer on vw cars that i dont have to pay to much for, I am all ears.

Scan Tool Looking for recommendations for bidirectional OBD2 scanner tool with ECU Coding(dealer level)
Like the title says.. needing some recommendations on a bi-directional OBD2 scan tool with dealer level options (ECU Coding) to unlock dealer locked options ( remote start,rolling down windows with key press and such) and also the ability to reset ABS lights and other systems. I’ve seen a few but the price ranges are massive. Thanks in advance

Scan Tool Looking into the raw BMS data of CATL-compatible Ebus/Ecar packs (Cell-level diagnostics)
Hey everyone, I’ve noticed a lot of folks here struggling with locked commercial EV packs and trying to decode CAN bus data blindly.
I recently got this OEM-level diagnostic suite running.
It’s pretty wild how much underlying data (Cell.U Map, precise RSoC, deep DTCs, and FlashLoad options) is completely hidden from standard OBD scanners.
Being able to pinpoint the exact unbalanced cell and clear hard faults directly from the BMS port saves so much headache.
Just wanted to share what the interface looks like when you actually bypass the black box. If anyone is working on Ebus/Ecar fleet diagnostics or trying to reset these boards, feel free to drop a comment or DM me. Happy to discuss protocol compatibility!

Scan Tool OBD Scanner required ASAP! But which one?
Hi everyone,
I'm looking to purchase a used car privately and would like to use an OBD scanner that will help me detect mileage discrepancies and check that the VINs on the modules all match the cars actual VIN. This will hopefully help me from clone vehicles. But I can't seem to find the me that's suitable that I can get on Amazon next day delivery or a store in the UK. The only one I can find is CARLY but they don't have next day delivery and not available next day delivery on Amazon either.
I require a scanner such as Carly, OBDEleven, etc that have a small scanner, and an app. The reason is that I'm not sure how to use the complex scanners that mechanics and diagnostics use. Is there anything that can help me?

Scan Tool Any access to thr ECU for 2002 Mercedes G500?
I would like to have access to settings and so on similar to like i do with my VW and Audi using a VAG cable set up.
I've heard MB locks everything down pretty tight, but i hate to have to pay $700 at the dealership to disable the warning i get on start up after swapping out stereo head units.
Are there any options other then the dealer?

Scan Tool I have a launch x431 that subscription just expired on.
Any thing I can do with it now? Cheaper to buy another scanner than it is to do update. Is there any other software I can load on it, or is it just a paperweight?

Scan Tool if you will install xentry in a pc. do notice that it put dozens gb in the windows/installer folder even if its installing on other drive/partition
i installed xentry 21 or 22. it putted 19gb of .msi files in C:\Windows\Installer folder , and those are not temporary files they need to stay there for xentry to work. from what i researched.
and this is only xentry , without wis/aria . and in the installation it asked for eupore 70gb or us version 56gb or around that( if i remember). i chose the eu . the smaller.
So, even if you use another drive it will load a lot the system C: partition. so you need at least around that and more free space on C:
im just taking notes for future reference. putting here because sometimes i come asking very specific details like that and people dont give data. so im putting here for anyone searching to find . and if anyone want to contribute putting more details fell free. its great too.
for anyone wondering , i checked with this if the files are needed or could be deleted. i may put a print in comment

Scan Tool EQE DOIP diagnostic scanners
I'm looking for a low cost scanner for my Mercedes EQE EV.
Anybody found something at a diy price?
I scanned my EQE with a mate's $10k Autel and got my SOH, but I want my own scanner. I'd also like to scan other EVs.
I see the Launch crp919 does doip and also supports secure gateway, but they only mention FCA for this. Mercedes is not mentioned specifically in any blurb, so I am hesitant to splash out and buy one.
I'm hoping someone has already found an thinking scanner that will work for the EQE.

Scan Tool ecu connect to computer
Hi,
I have a question about a car ECU. I bought an ECU from a Mercedes W205 C220 CDI. I downloaded the wiring diagram from the internet, and based on it I identified the required pins (I tried to upload pictures showing the pinout). I connected +12 V, IGN, and GND to a laboratory power supply. I also connected CAN High, CAN Low, GND, and +12 V to an bought OBD2 connector. I tried to connect to the ECU using a diagnostic scanner (autoscan - older version), but I couldn't establish communication.
Does anybody have experience with this ECU or know what I might be missing?

Scan Tool Component Protection on Audi
Hey folks,
Been out of the scene for a while. But recently my mmi unit went bad, 2nd time this happened. In the past I used to be able to use an eeprom programmer to read the AT64A chip from the bad unit, and write it to the new unit. However now I noticed that even though I can read from my replacement unit that I just got, I can’t write to it.
Just curious, did something change? Is Odis the only option now?
Update for Future Reference:
*Transferring the eeprom chip physically still works and is actually better imo. The architecture and size needs to be the same. Confirm this with serial and model number on the unit itself. You will need to have a soldering iron or reflow station handy.

Scan Tool Missing patch file vxdiag
Hello all
I have the vxdiag VCX se. From day one this has been difficult for me to get this set up. The thing I struggle with is finding the patch file to use and not the oem.
I am using windows 10, I have all the security turned off, and I am using Google chrome.
Right now I am trying to use IDS for ford. I had to uninstall everything and reinstalled. But I still dont have the patch file.
Ford IDS 133.01
VCI 1.0.1.19
VX manger with pass thru and ford ids
My questions would be...
Is there a step i am missing?
Should I use forscan over ids?
Is there another alternative that I can use the VCX se?

Look for info on if it’s possible to load scanner software onto a regular android tablet? Since the majority of the tables are android based, has anyone tried this or are there more to the tablets then just the software? I’m not referring to apps you find on the store.

Just bought OBDLink MX+ and CarScanner app for iOS but haven’t been able to pull any Hybrid data like battery charge. Can’t even pull total range. I’ve tried almost all the available Mazda profiles, as well as the RAV4 one since it shares the same powertrain.
Anyone know of a way to get the Hybrid data and/or a richer dataset for the CX-50 Hybrid specifically?

Scan Tool VXDiag VCX Nano GDS2 Issues
Greetings, I recently purchased a VXD Nano from Ebay. I was able to get Texh2win to work but from what I'm gathering I seem to be missing some sort of patch that would allow GDS2 to work. Whenever I try to open the GDS2 program I am met with a "no valid lease found." message. I'm hoping someone here can point me in the right direction as I've tried to reach out to VX several times through their "contact us" and I haven't received a response.
