OBDLink MX+ / bluetooth connection disconnecting

« Last post by mhixson on February 12, 2026, 11:27:10 pm »

Vehicle: 1996 AM General Hummer. GM 6.5TD.

Hi, I've been using an OBDLink MX+ for a couple years. I run it always connected to my 1996 Hummer. I have a Raspberry Pi that connects via Bluetooth and records data. This has been rock solid up until a few weeks ago. Every once in a while the reader just stops returning data and the blinkenlights stop flashing. Sometimes the connection between the Pi and MX+ will restore in a few seconds and sometimes it seems to be disrupted until I unplug/replug the MX+.

I had thought something was going wrong with my Pi, but this evening I saw the exact same behavior between the MX+ and my iPhone running the OBDLink app or DashCommand.

I do know there was a firmware update for the MX+ that I applied sometime around when I started noticing this happening, but I can't say 100% that the problem started right after the update.

Anyone else seeing this? Any known fix?

Are you using a particular app to connect to your vehicle?

The OBDLink app does not have access to OEM data, which you more than likely will need.

We would recommend trying Carista, which should have OEM data for your vehicle.

Hi everyone,

I'm currently developing an OBD2 diagnostic app for BMW vehicles and I've run into a roadblock during the App Store review process. Apple rejected my build under Guideline 2.1.0, requesting authorization for the following MFi protocols: com.obdlink.protocol, com.obdsol.obdlink, and com.stn.protocol.

I am aiming to support OBDLink hardware. For those who have successfully published apps using these adapters, what is the best way to obtain the PPID (Product Plan ID) or authorization from OBD Solutions?

Does anyone have a specific contact point or a form that needs to be filled out for third-party developers? Any guidance on how to phrase the App Review Notes to satisfy the reviewers would be greatly appreciated.

Thanks in advance!

General OBD Questions / VW Tiguan R-Line 2021 Remote start not working

« Last post by immortalsoul on February 07, 2026, 02:17:06 am »

Hi everybody,

I have a VW Tiguan, and since the day I bought it, the remote start system hasn’t been working. I consider myself a handyman and a car enthusiast, so I started digging into the issue. I got a scan tool (I’m not familiar with these devices — I borrowed it from a friend).

I scanned the car and started looking for modules responsible for the remote start system, but I didn’t find the exact module. I compared my results with the same car on which the remote start works perfectly, and everything looked the same. I also compared the fuse boxes and the components inside — everything is similar.

I checked the key fob battery (replaced it with a new one). The car has gasoline (full tank). All of the doors are closed, and the car battery is in good condition. When I press the lock button and then the key fob button twice, the car’s emergency lights blink twice, but nothing happens. I tried all the different combinations I found on the internet to start the car.

Is there anyone who can give me some hints or instructions on what else to check or how to fix it? I’d really appreciate it.

OBDLink CX / Re: obdlink mx+

The Kia enhanced add-on that is available is limited to manufacturer-specific diagnostic trouble codes (DTCs) only.
At this time, we do not support live OEM sensor data or manufacturer-specific parameters for Kia/Hyundai vehicles, so enhanced data such as live engine or actuator values will not appear even though the add-on shows as installed.

ECUsim / Re: Can not connect to ECUsim 2000 from ECUsimcommander

Is FT_Prog (a utility from the USB IC manufacturer) able to detect it?
Link to download FT_Prog

Download, install, and run FT_Prog.
Unplug as many USB as you can, except for the ECUsim.
Click the magnifying glass icon to scan for FTDI devices.
Post a screenshot of the results.
