OBDeleven 3 OBD2 Diagnostic and Coding Tool
OBDeleven 3 is a palm-sized Bluetooth diagnostic tool that plugs into the OBD2 socket and works through an app on your phone. No cables, no laptop, no trip to a garage. It is officially licensed by the Volkswagen Group, BMW Group, Toyota Group, Ford Group (US models) and Mercedes-Benz — the fundamental difference between it and a generic ELM327 clone.
In short: free, unlimited OBD2 diagnostics and live data on any CAN-bus vehicle from 2008 onward. On licensed brands: full-system diagnostics, One-Click Apps for hidden features, and manual coding and adaptations on VAG vehicles. 5 CAN-FD channels, automatic baud rate detection, sleep mode and ignition detection. Works with Android 8.0+, iOS 16.6+ and HarmonyOS.
Three Steps to Start
- Plug the device into the car's OBD2 socket — usually in the panel under the steering wheel.
- Download the OBDeleven app — Google Play, App Store or AppGallery.
- Pair the phone with the device over Bluetooth. That is the whole setup.
The device has a smart power-saving mode: it sleeps with the ignition off and does not drain the battery. So it can stay plugged in permanently — which means you can look at a warning light the moment it appears.
What Changed in OBDeleven 3
The difference from the previous NextGen generation is not just speed; it is what the hardware can reach:
| Hardware | OBDeleven 3 | OBDeleven 2 (NextGen) |
|---|---|---|
| Processor | STM32G0 32-bit · 256 kB Flash · 144 kB SRAM | STM32F1 32-bit · 128 kB Flash · 64 kB SRAM |
| CAN channels | 5× Classical CAN / CAN-FD | 1× Classical CAN |
| Automatic CAN baud rate detection | Yes | No |
| Sleep mode | Yes | No |
| Ignition detection | Yes | No |
| Bluetooth Low Energy | Yes | No |
| Automatic vehicle identification | In development | No |
Five CAN-FD channels matter in practice: modules in a modern car do not sit on one bus but several. A single-channel tool reaches those buses one at a time; a five-channel tool reaches more modules faster. Full Mercedes-Benz functionality requires the OBDeleven 3 hardware — the NextGen cannot do it because of its hardware limits.
What It Does
OBD2 diagnostics
On every brand with CAN bus from 2008: read, clear and share engine and transmission faults. Free and unlimited.
Advanced diagnostics
On licensed brands, faults from all available systems — ABS, airbag, climate, body and comfort modules included.
Live data
Engine speed, coolant and oil temperature and more, on any CAN-bus car from 2008.
One-Click Apps
Enable hidden comfort and safety features and reset service reminders in a few taps. Uses Credits.
Manual coding
Channel-level coding and adaptation on VAG vehicles, including SFD-locked features. Requires PRO or ULTIMATE.
Hybrid battery check
Cell balance and temperature on Toyota and Lexus hybrid and electric vehicles — early signs of wear.
Car inspection
A checklist for buying used, likely issues by mileage, and a one-scan health summary.
Vehicle information
Year, mileage, engine code and body type from the VIN. On licensed brands, the factory options list too.
Supported Brands
The tool works at two levels, and it is important not to confuse them:
| Level | Coverage | What you can do |
|---|---|---|
| OBD2 level | Every brand using CAN bus from 2008 | Read and clear engine and transmission faults, live data |
| Manufacturer level | Volkswagen, Audi, Škoda, SEAT | CUPRA, Bentley, Lamborghini, BMW, MINI, Rolls-Royce, Toyota, Lexus, Ford (US), Mercedes-Benz | Full-system diagnostics, One-Click Apps, coding, vehicle information |
Limits worth knowing before you order. From the manufacturer's own notes: 2024+ Volkswagen Group vehicles with the SFD2 security system are not currently supported. BMW advanced diagnostics is unavailable in some countries and some functions are limited on 2024+ models. Ford features work only on vehicles built in the US. We state these up front — send us your model year and we will check it before you order.
Plans: FREE, PRO and ULTIMATE
The device ships on the FREE plan, and it is useful even there: OBD2 diagnostics and live data are unlimited and cost nothing. Advanced features need a plan:
| Feature | FREE | PRO | ULTIMATE |
|---|---|---|---|
| OBD2 diagnostics and live data | Unlimited | Unlimited | Unlimited |
| Advanced (full-system) diagnostics | — | Yes | Yes |
| One-Click Apps | With Credits | With Credits | Almost unlimited |
| Manual coding and adaptations (VAG) | — | Yes | Yes |
| Duration | Unlimited | 12 months | 12 months |
What are Credits?
One-Click Apps are ready-made recipes in the app: enable the roadside-assistance function, tie mirror folding to a speed threshold, adjust daytime running lights. Each app costs a number of Credits, bought once. The ULTIMATE plan instead gives almost unlimited access to those apps under a fair-use policy.
Use the selector at the top of the page to take the device on its own or add a Credit or plan pack; the total updates with your choice.
Which Plan for Whom?
| Situation | Recommendation | Why |
|---|---|---|
| I want to know what the warning light means | Device only (FREE) | OBD2 diagnostics and live data are already free and unlimited |
| I want to enable a few hidden features | Device + Credits | A one-off job; no plan needed |
| I will do channel-level coding on my VAG car | PRO pack | Manual coding and adaptation unlock with PRO |
| I run a workshop and will work on many cars | ULTIMATE pack | Almost unlimited One-Click Apps, no Credit counting |

Who It Is For
- Car owners who want to understand their own vehicle instead of driving to a garage for every fault
- Enthusiasts who want coding and adaptations on VAG vehicles
- Buyers checking a used car's fault history and factory options
- Toyota and Lexus drivers monitoring hybrid battery health
- Small workshops wanting a fast pre-scan tool alongside a professional device
It does not replace a professional diagnostic tool. OBDeleven 3 is a phone-based tool that goes deep on specific brands; bi-directional actuator tests, ADAS calibration and ECU programming need a workshop device such as the TOPDON ONE or THINKTOOL Expert 391. Tell us what work you plan to do and we will find the right tier together.
