You get into a friend’s car and immediately notice. When locking, their mirrors fold in. The lights stay on a bit longer to illuminate the way. And the speed is displayed large on the dashboard. “How did you do that?” you ask. The answer is a small device: the OBDeleven. Many of those features are already in your own car. They’re just turned off at the factory. With the OBDeleven 3 ULTIMATE Pack, you activate those hidden features yourself. No garage needed and no coding knowledge required. Below you’ll read how it works, why this is the ideal diagnostic device for daily use, and which cars you can read and code with it.
What is the OBDeleven 3 ULTIMATE Pack?
The OBDeleven 3 is a small, smart OBD2 diagnostic device. You plug it into your car’s OBD2 port, usually under the dashboard. Via Bluetooth, it connects to the free OBDeleven app on your phone. Do you drive a Volkswagen, Audi, Škoda, SEAT, or Cupra? Then it’s an affordable alternative to VCDS (also known as VAG-COM). The ULTIMATE Pack gives you everything to start reading and coding right away:
The OBDeleven 3 adapter · the latest generation, fast and stable via Bluetooth.
The ULTIMATE plan (12 months) · the highest subscription, with all features unlocked and unlimited One-Click Apps.
A handy storage case · so you can neatly store your diagnostic device in the glove compartment.
In short: a ready-to-use package. You read your car yourself, code it, and customize it. Without expensive dealer equipment and without a laptop.
Activating hidden features: that’s what you buy OBDeleven for
Your car can probably do much more than you think. Manufacturers build in handy features as standard. But they turn them off at the factory. With OBDeleven, you activate those hidden features yourself. No garage needed and no technical knowledge required. For most people, this is the main reason to buy an OBDeleven. A few popular examples:
Comfort & Appearance · folding mirrors when locking, coming home and leaving home lights, and a smooth sweep of the needles when starting.
Driving Experience · a digital speedometer, your fuel consumption or RPM displayed larger, or a lap timer for the track.
Remove annoyances · disable the start-stop system by default, turn off the seatbelt signal (beep), or hide notifications.
The nice thing: you can just as easily reverse any adjustment. So you can experiment calmly. Your car remains yours.
How does it work? With One-Click Apps
Activating hidden features sounds complicated. It’s not. In the OBDeleven app, you find One-Click Apps. These are ready-made adjustments you turn on or off with one tap. You don’t need coding knowledge and you can’t break anything. You choose the function, tap execute, and done. OBDeleven has thousands, neatly organized by brand and model.
This is where the ULTIMATE Pack shines. With the ULTIMATE plan, you use the One-Click Apps unlimited. With PRO, you pay per adjustment with credits. With ULTIMATE, you enable as many functions as you want without extra charges. Want to activate many hidden features? Then the ULTIMATE Pack is by far the most cost-effective.
Also ideal for daily use and diagnostics
The OBDeleven is more than a coding tool. It’s also a handy diagnostic device for everyday use. Does the engine light come on? You’ll know what’s going on within a minute.
Read and clear fault codes · read fault codes (DTCs) with clear descriptions. Have you fixed the problem? Then clear them again.
Watch live with your car · view live data such as temperature, RPM, and battery voltage while driving.
Always at hand · the Adapter stays in your car. You already have your phone with you. No laptop, no hassle.
What else do you get with the ULTIMATE Pack?
Besides unlimited One-Click Apps, the ULTIMATE plan unlocks more than PRO or the basic plan:
Coding & SFD unlock · manually code and unlock secured features on newer models (2020 and later).
Extra checks · check a hybrid battery and the mileage. Useful when buying a used car.
Priority support · your questions are handled with priority.
Which cars does the OBDeleven read?
The OBDeleven works on almost any car with an OBD2 port, roughly from 2008 onwards. How many hidden features and coding options you have depends on the brand. There are roughly three levels:
New in 2026: Mercedes-Benz now fully supported. Mercedes has been added as a full brand, with diagnostics, One-Click Apps, and coding, just like the Volkswagen group. Many OBDeleven guides do not mention this yet.
| Level | What it can do | Brands |
| Complete | Diagnostics + One-Click Apps + coding | Volkswagen, Audi, Škoda, SEAT, Cupra, Bentley, Lamborghini, Mercedes-Benz |
| Apps + diagnostics | One-Click Apps + fault codes | BMW, MINI, Rolls-Royce, Toyota, Lexus, Ford |
| Diagnostics | Fault codes + live data | Many other brands |
Most hidden features are found in the Volkswagen group: Volkswagen, Audi, Škoda, SEAT, and Cupra. New is that Mercedes-Benz is now fully supported as well. But BMW, Toyota, and many other drivers also enable plenty of functions with it. Want the full overview per brand? Then check out our blog OBDeleven: which cars, what it can do, and which plan.

Frequently Asked Questions
Can I enable hidden features?
Yes. For most people, that is the main reason to buy an OBDeleven. With One-Click Apps, you can turn functions on or off with a single tap. No coding knowledge needed.

Yes. For many VAG drivers, OBDeleven is an affordable alternative to VCDS (also known as VAG-COM).
