If you are familiar with Autel diagnostic tools, the OTOFIX D1 Lite is almost identical but with a more affordable price tag. Being a “Lite” model, it’s a car diagnostic tool that targets DIY mechanics who want to carry out repairs and services on their own cars. Of course, if you require more advanced functions, there is a “Pro” model, but for the average car owner, it really isn’t worth paying the extra for, and it’s the reason why the Lite model is far more popular.

As we have access to a range of vehicles, we’ve had the chance to test the OTOFIX D1 Lite thoroughly. From VAG cars (Volkswagen, Audi and Skoda) to Mercedes, we’ve carried out full system diagnostics, viewed live data, made adaptions and carried out some of the tool’s “Hot Functions”, such as the DPF regeneration and opening of the EGR valve.

Our Review

To thoroughly test and assess the OTOFIX D1, we’ve been using it on various OBD2-compatible vehicles.

In this review, a 2017 Volkswagen Tiguan 2.0 TDI (R-Line) was the test vehicle with some stored error codes, and it was also a car where we wanted to view the DPF filter content as it’s mainly used for short journeys.

Is The OTOFIX D1 Lite For Me?

When it comes to choosing an OBD2 scanner, you have hundreds of tools to choose from. Therefore, in such a crowded market, OTOFIX has made sure their D1 Lite stands out with its features, build quality and the backing of the Autel brand.

From OEM-level diagnostics to viewing live data, even as a novice user, you’ll quickly get to grips with navigating the various menus and functions. It really is a scan tool that’s suitable for all experience levels, and with its wide vehicle compatibility, you won’t need any other tool (unless you are a professional mechanic requiring advanced functions).

What Is In The Box?

  • Main tablet
  • Power adapter
  • USB Cable
  • Three-way USB adapter
  • Carrying case

How Easy Is It To Use?

As the D1 Lite has been designed for all experience levels, it has to be easy to use, and in short, it is.

To begin using the tool, you need to plug the V1 device into your OBD2 port, which is usually underneath your steering wheel. As shown in the photos below, the V1 is compact, and it also comes with a useful torch that helps you find the OBD2 port (we love this feature!). Once plugged in, it’ll light up, and you can proceed to use the scan tool.

Review of Otofix D1

As long as the V1 is correctly plugged into your car’s OBD2 port, you’ll be able to navigate your way to the diagnostics on the tablet, where the device will then attempt to “Auto-Detect” your vehicle (as shown in the photo). If, for some reason, it didn’t automatically detect your car, you can manually input your car’s data.

Once the connection is successful, you can go straight into full systems diagnostics, service functions, viewing live data, and so much more. It really is as simple as using any other tablet (i.e. an iPad), and the brand has done an excellent job with the user interface.

If you haven’t used a diagnostic tool before, we highly recommend reading our guide on how to use OBD2 scanners.

How Good Is The Diagnostics?

The main part of any OBD2 scanner is the diagnostics, and the OTOFIX D1 enables you to carry out an OEM-level full systems diagnostic test in just a few clicks. According to the brand, the D1 Lite is compatible with 99% of cars worldwide and with the diagnostics, you can read codes, erase codes, view freeze frame and live data, and ECU information. It also benefits from bi-directional active tests, meaning you can verify component input and output values.

As shown in the photos (and video) below, the diagnostic test runs through all control units and indicates whether there are any error codes. Once the test has finished (it takes 1 to 5 minutes, depending on the car), you can click on any error codes to read the stored code and erase it. If, after rerunning the diagnostics, the error code still exists, you’ll need to rectify the issue before you can erase it.

A great feature that’s worth mentioning is that the D1 Lite provides historical diagnostics tests, and this is useful because you can see past error codes that you may have forgotten about but are still present.

Below is a video we posted on our YouTube channel that displays just how quickly and easily we were able to carry out the diagnostics with the V1 plugged into the OBD2 port.

Other Functionality

As well as comprehensive diagnostic reports, the OTOFIX D1 Lite offers 38 service functions such as resets (i.e. oil, airbag and much more) to DPF regeneration. Unlike other scanners we’ve tested, these functions aren’t hidden in various menus but instead can be carried out quickly in just a few clicks.

Otofix D1 Functions
Otofix D1 Reviews

As shown in the photos above, the functions are clearly labelled with an icon and large text, and when carrying out any of these service functions, the tool guides you through each step to avoid any mistakes.

As well as walking you through the process, the terminology used isn’t filled with technical jargon that novice users may find too complex. For example, in the above service function, we wanted to know if the DPF required a cleaner to keep the filter clean. Therefore, before regenerating the DPF, the tool read the current oil ash volume (which was at 30% capacity) and clearly stated that the filter didn’t need a replacement.

The Build Quality

As the OTOFIX tool is part of the Autel brand, it uses many of the same components, and as with Autel’s scan tools, the D1 Lite is just as high-quality.

As you can see in the image, the D1 Lite is very thin and lightweight, but it certainly feels robust in your hand. Although we haven’t dropped the scan tool yet, we are confident it will survive without a scratch.

However, it’s not just the tablet that is built to a high standard because the V1 and even the carry case are built just as well. The rugged case has compartments for each scanner component and even a sturdy strap to hold the tool in place during transport.

OTOFIX D1 Lite vs D1 Pro

You may or may not be aware, but the brand offers several versions of the D1 with the Lite, Pro, Plus and Max models. However, the two most popular models are the Lite and Pro, with the Pro being the more expensive.

In a nutshell, the main differences include the fact that the Pro features a larger tablet (10 inches instead of 7 inches), dual cameras and a newer Android operating system. In terms of diagnostics, the Pro also has further functions and programming abilities that may be required for more advanced users.

Regarding which one you should buy, we firmly believe that the D1 Lite offers everything you need as an enthusiast, DIY mechanic, or as a secondary diagnostic tool if you are a professional. However, if the additional functions are a dealbreaker, paying the extra for the D1 Pro may be the better option.

OTOFIX D1 Lite Pros & Cons

  • Very easy to use (Bluetooth connection) for the average car owner who wants a diagnostic tool that offers more than the basic alternatives
  • OEM level full system diagnostics and bi-directional active tests
  • Over 38 maintenance service functions and compatibility with 80+ manufacturers and 10,000+ vehicle models
  • High-quality, stylish and robust 7-inch tablet that runs on the reliable Android 9.0 operating software
  • Desirable cloud-based report management for convenient access to diagnostic data and test results
  • Comes in a sturdy carry case with straps that hold the tablet in place
  • Every component is built to last and it comes with a two year warranty
  • Powered by Autel diagnostics and features their excellent technical support
  • Comes with a 2-year subscription but after that period, you'll need to pay for the renewal for further updates (these updates aren't required to use the tool but you won't have access to new features that are released by the brand)
  • Doesn't come with an integrated stand

YourCar's Verdict

If you are in the market for a mid-range OBD2 scanner that offers OEM-level diagnostics and plenty of functionality, the OTOFIX D1 Lite is the tool for the job.

Compatible with most cars on UK roads, you can perform a full system diagnostics in just minutes with a few clicks. There are also several functions, such as DPF regeneration, oil level resetting, and so much more, that can be performed just as easily.

For the average car owner who repairs and services their cars, the OTOFIX D1 Lite is everything you need and more. At its price point, we haven’t tested any other scan tools that come close in terms of vehicle compatibility, features, usability, build quality and technical support. Apart from lacking a stand and there being a subscription for further updates, it’s the best mid-range OBD2 scanner on the market.
