How to code your Volkswagen and Audi after retrofits with OBDeleven
Retrofitting is a smart way to upgrade your vehicle without breaking the bank on a brand-new model. With the right tools and know-how, it can boost performance, add convenience, or even extend your car’s life.
But here's the catch: modern cars are a little more complex than just swapping out one part for another. You need to configure or program new components to work seamlessly with your car's systems. In this guide, we'll walk you through how to use OBDeleven to code your retrofits.
What’s retrofitting for cars?
In simple terms, retrofitting is upgrading your car with features it didn't originally have to suit your needs better. For instance, if you own a lower-spec vehicle without a rear-view camera, you can retrofit your car with one by installing it.
Similarly, if your car uses bulb license plate lamps, you could retrofit them with LED lamps. This can improve the car's visibility and make the lighting more energy efficient.
Why is coding necessary for car retrofits?
Car retrofits need to be coded or programmed to ensure new features work correctly with the car's existing systems. When you add new features or upgrade existing ones, the car's computer system needs to be informed of the changes so that it can adjust and optimize the performance of the new components.
Take the rear-view camera as an example. After you install it, your multimedia system needs to be told, "Hey, there's a camera now, so display it when the car's in reverse." This might involve changing car settings for the new camera to work properly.
Another common retrofit example among Volkswagen Golf owners is upgrading license plate lights from halogen bulbs to LEDs. Your car’s diagnostic system might flag this as an issue because it doesn’t recognize the new setup. This can trigger error messages on your dashboard or even cause flickering lights. Coding fixes these problems, ensuring everything integrates seamlessly.
In short, coding ensures that all retrofits are properly integrated, function as intended, and don’t show unnecessary fault codes.
How to code retrofits with OBDeleven?
OBDeleven NextGen is a small but powerful tool that plugs into your car’s OBD2 port and gives you access to its computer system. Paired with its mobile OBDeleven VAG app, it allows you to perform various diagnostic and coding tasks, including retrofits.
OBDeleven offers two main approaches to retrofitting:
1. Manual coding, where you modify all settings yourself by coding control units. This involves adjusting specific values or parameters to fine-tune how certain systems behave.
This method offers complete control over your vehicle but requires some research and technical knowledge to understand the coding options and their impact. To access these advanced coding features, you’ll need the PRO VAG or ULTIMATE VAG plan.
2. One-Click Apps – our pre-coded customization options – that allow you to enable or disable features with a single tap, no technical expertise required.
Now, let’s take a look at how each of them work.
Manual retrofits coding
Manual coding offers a wide range of possible modifications, allowing you to customize almost every detail of your car. However, it does require some knowledge and understanding since you're dealing with your car's “brain.”
1. Install components you want to retrofit
Start by physically installing new components. Follow the manufacturer's instructions or wiring diagrams carefully to ensure everything is correctly connected. Otherwise, you may cause damage to your car or components.
2. Research coding information
Once installed, the next step is to figure out the specific coding required. If your retrofit vendor doesn't provide instructions, look online for coding manuals specific to your car model. But be careful – not everything online is trustworthy. Stick to reputable forums, manuals, or video guides, and double-check every step.
3. Connect to OBDeleven app
When you're ready, connect your OBDeleven device to the OBD2 port (usually under the driver's dashboard) and open the OBDeleven VAG app. From there, tap "Connect" and wait a few minutes for the connection to establish.
4. Access control units
Next, navigate to the control unit list. If the retrofit involves installing an additional control unit, the OBDeleven VAG Android app will typically detect it automatically and prompt you to install it. On iOS, you might need to add it manually by tapping the pencil icon in the top right corner.
After connecting, use features like Long Coding and Adaptations to tweak the settings. For instance, if you've added a trailer hitch, you need to make changes in multiple control units, like the engine, brakes, and more.
Pro tip: Always create a backup of your car’s original coding settings before making changes. OBDeleven’s backup feature will help you revert settings if something goes wrong. Follow these guides to learn how: Android Backup Guide | iOS Backup Guide.
5. Test and verify
Finally, test the new feature and run a full scan to ensure there are no new fault codes. If something seems off, revisit your coding steps and adjust as needed.
Coding retrofits with One-Click Apps
If manual coding sounds too complex or time-consuming, OBDeleven’s One-Click Apps are here to simplify things. These pre-configured coding options let you enable retrofits, customize features, or disable annoying functions in seconds.
You'll need OBDeleven Credits to use these One-Click Apps, which you can buy directly in the app. Alternatively, the ULTIMATE VAG plan gives you unlimited access to Volkswagen Group One-Click Apps at no extra cost.
Here’s how to activate One-Click Apps:
1. Plug in the OBDeleven dongle to your car's OBD2 port
2. Open OBDeleven or OBDeleven VAG app and tap on “Connect”
3. After it connects, tap on the vehicle icon below
4. Open the "Apps" tab
5. Choose the "Retrofits" category
6. Select the One-Click App for your retrofit and activate it
What else can you do with One-Click Apps?
OBDeleven One-Click Apps aren’t just for retrofits. Here are some of the most popular One-Click Apps among Volkswagen and Audi drivers:
1. Oil Service Reset: Quickly reset the oil service indicator after an oil change, ensuring accurate maintenance tracking
2. Inspection Service Reset: Reset the inspection reminder to keep your vehicle’s service schedule up to date
3. Brake Pad Replacement: Activate service mode on electronic parking brake to replace rear brake pads
4. Seat Belt Warning: Enable or disable the seat belt warning chime based on your preference
5. Gauge Test - Needle Sweep: Perform an instrument cluster test by sweeping the gauge needles through their full range each time you turn on the ignition
Note: Different One-Click Apps are available for different brands. Check out our supported vehicles list to find what’s possible for your car.
Wrapping up
Retrofitting your car can be a rewarding project, but it’s not always plug-and-play. With OBDeleven, you can bridge the gap between old and new, ensuring every feature works like it was factory-installed.
Whether you prefer the hands-on approach of manual coding or the simplicity of One-Click Apps, OBDeleven gives you the tools to take control of your car. So go ahead, give your vehicle that personal touch – and enjoy the ride.
