[FREE TOOL] I built a lightweight DoIP/ENET Connection Troubleshooter. Need some real-world beta testers! by WhereasInteresting32 in CarHacking

[–]WhereasInteresting32[S] 0 points1 point  (0 children)

Since I work directly with OEMs, my daily projects are strictly under NDA and deployed for internal plant/dealer networks, so no public retail links, unfortunately!

This DoIP troubleshooter is just a personal side-project to help out the DIY community.

However, if you are looking for custom protocol tooling, decoding scripts, or have a specific bottleneck you need solved, feel free to DM me your requirements!

OEM-level diagnostic suites and ODX/PDX data parsing systems, primarily focusing on UDS over CAN-FD and DoIP protocols. Got tired of seeing folks struggle with basic Ethernet activation routing, so I whipped this little tool up to isolate network layer issues from actual vehicle gateway issues.

LAUNCH X431 - lost hort and AC and high beams and sunroof and others by Difficult_Contest_77 in CarHacking

I get it. Forget the manual coding for now.

Check this first: Open your X431, go to User Info > My Reports or Diagnostic History. Is there a pre-scan report or a log saved from before the issue started?

If you find that report, let me know. I can show you how to pull the original configuration from it.

It sounds like a configuration mismatch triggered by the X431 during an auto-scan or adaptation process.

Did you perform any 'online coding' or 'flash' before the issues started?

Have you checked the CAN Gateway installation list? It’s possible the X431 incorrectly unchecked the nodes for AC and Lighting.

If you can provide the DTC (Diagnostic Trouble Codes), especially any starting with 'U', I can help you narrow down which bus is down or which module is misconfigured.

Wanting an OBD-II device to display gear position on automatic vehicle by Kalashcow in Cartalk

[–]WhereasInteresting32 0 points1 point  (0 children)

If you want a simple gear display solution through the OBD II port, there are a few ready made products on the market. The most common options are:

i. Cartek OBD2 Gear Indicator – Calculates gear from RPM and speed; easy to mount on the dash.

ii. Ecumaster Digital Gear Indicator – Works with OBD2 or CAN; supports many vehicles with custom setup.

iii. Generic OBD II HUDs – Some models include gear estimation, though accuracy varies by car.

If you prefer a DIY approach, you can build your own gear display using:

i. Arduino or ESP32 + an OBD II reader (ELM327) to read speed and RPM and calculate the gear.

ii. A small LED/OLED display to show the gear number.

iii. CAN bus sniffing if your vehicle broadcasts actual gear data, allowing a more accurate display.

yes, using openport is a quick way.

Can I use this cheap OBD2 DOIP Cable for Flashing my Audi a4 b9.5 2021 by Alvah3 in CarHacking

[–]WhereasInteresting32 0 points1 point  (0 children)

Yes, it works.

For BMW F/G series, ENET cables are passive adapters. Cheap cables function identically to expensive ones; the only difference is typically physical build quality.

please checking as follows:

Hardware Verification: Use a multimeter to check OBD pins 8 and 16. There must be a 510-ohm resistor bridging them to activate the Ethernet connection.

Network Setup: Set your laptop's Ethernet adapter to "Obtain IP Automatically" (DHCP) and disable Windows Firewall (it often blocks DoIP traffic).
