Trip to Iceland: Time to get the engine code reader

I am leaving in a few weeks on a road trip from the UK to Iceland in a campervan. You may have read prior posts about tyres. Now I am working on other important things. I bought car chains already as there may be snow and ice in areas in late October. I have always been interested in the engine code reader and thought it would be a helpful addition.

As I do with many research tasks these days. I will partner up with Claude Sonnet and ChatGPT 4o to help me get kickstarted with my research.

Prompt:
Trip to Iceland: Time to get the engine code reader
I have been meaning to get one of these readers. I want to better understand how to evaluate what is a good option to use. I have a volkswagen T5.1. What do I do?

To use it:

1. Locate your vehicle’s OBD-II port (usually under the dashboard)
2. Plug in the scanner or connect wirelessly
3. Turn on your vehicle’s ignition
4. Follow the scanner’s instructions to read codes or perform diagnostics

Would you like more details on any specific aspect of choosing or using an engine code reader?

Getting an engine code reader (also known as an OBD-II scanner) is a great idea, especially if you’re planning a road trip to a place like Iceland, where you might be far from service centers. Here’s a step-by-step guide on how to choose a good option for your Volkswagen T5.1 and how to use it:

1. Understand What You Need

• Compatibility: Make sure the OBD-II scanner is compatible with European vehicles, especially Volkswagen. The T5.1 should use a standard OBD-II port, but some Volkswagen vehicles may require a scanner that can read VW-specific codes.
• Functionality: Decide what features you need. Basic scanners only read and clear codes, while more advanced models can provide real-time data, freeze frame data, and more. Some can even perform manufacturer-specific functions like ABS, SRS, or transmission diagnostics.
• Portability: If you’re going to be traveling, a compact or Bluetooth scanner that works with your smartphone might be more convenient.

2. Types of OBD-II Scanners

• Basic Code Readers: These can read and clear generic OBD-II codes. They are usually inexpensive and simple to use.
• Enhanced Code Readers: These provide more detailed information and can access additional systems like ABS, airbags, and transmission.
• Professional Scanners: These are more expensive but offer in-depth diagnostics, including manufacturer-specific codes and advanced functions like coding or programming.
• Bluetooth/Wi-Fi Scanners: These connect to your smartphone or tablet, allowing you to use an app for diagnostics. They are portable and offer a lot of functionality, but they depend on the quality of the app.

3. Recommended OBD-II Scanners for Volkswagen T5.1

• OBDeleven: This is a popular choice for Volkswagen and Audi owners. It’s a Bluetooth scanner that works with an app, offering both basic and advanced functions. It’s user-friendly and offers specific support for VW vehicles.
• VCDS (VAG-COM): This is a professional-grade diagnostic tool specifically designed for Volkswagen, Audi, SEAT, and Skoda vehicles. It’s a bit more complex to use but offers comprehensive diagnostics and is highly recommended if you want deep insights into your vehicle.
• Autel MaxiCOM MK808: This is a mid-range option that offers a lot of features for its price. It’s a standalone device, so you don’t need a smartphone to use it, and it offers a good balance between price and functionality.

4. Where to Buy

• Online Retailers: Amazon, eBay, and specialized automotive sites often have a wide selection. Make sure to read reviews and confirm the compatibility with your Volkswagen T5.1.
• Automotive Stores: Stores like AutoZone or local auto parts stores might carry basic and enhanced code readers.
• Direct from Manufacturer: Sometimes buying directly from the manufacturer’s website ensures you get the latest version and access to proper customer support.

5. How to Use the OBD-II Scanner

• Locate the OBD-II Port: In the Volkswagen T5.1, the OBD-II port is usually located under the dashboard, near the driver’s side.
• Plug in the Scanner: Insert the scanner into the OBD-II port. If it’s a Bluetooth scanner, connect it to your smartphone.
• Turn on the Ignition: Most scanners require the ignition to be in the “On” position, without starting the engine.
• Run Diagnostics: Follow the scanner’s instructions to run diagnostics. For smartphone-based scanners, use the app to read codes.
• Interpret the Codes: The scanner will display error codes. Look up these codes online or within the app to understand what they mean.
• Clear Codes (If Necessary): After addressing any issues, you can use the scanner to clear the codes.

6. Tips for Your Trip

• Bring a Backup: Consider bringing a basic code reader as a backup, just in case your primary scanner fails.
• Keep the Manual: Having the scanner’s manual or a reference guide can be helpful on the road.
• Update Software: Ensure your scanner’s software or app is up to date before your trip.

By selecting the right OBD-II scanner and familiarizing yourself with its use, you’ll be better prepared for any unexpected issues during your trip to Iceland.

Next step

With some basic information I felt ready now to do a basic thing which is to check that I had easy access to the code reader slot in the vehicle and see if there were any differences. The Transporter is 2015 and I also have a VW Caddy from 2008 so it could be good if the reader supports both.

I took pictures of the connectors on both vans. ChatGPT was able to help me confirm these connectors were the same and the ones uses as standard for on board diagnostics

Yes, both connectors in the images you provided are OBD-II (On-Board Diagnostics II) ports, which are used for engine code readers. These connectors allow diagnostic tools to access the vehicle’s onboard computer system to read error codes, monitor vehicle performance, and perform other diagnostic functions.

The pink-colored connector in both images is consistent with the standard 16-pin OBD-II interface commonly found in modern vehicles, particularly those manufactured after 1996.

Decided to give https://obdeleven.com/products?carBrand=Volkswagen a try. I also thought the company concept of building one click apps and helping make customising vehicle settings easier something that I am interested in learning more about.
