As a car enthusiast and DIY mechanic, I’ve gone through my share of OBD2 scanners. Like many, I started with the idea of saving money and finding the “best cheap OBD2 scanner.” In 2017, the market was already full of options, each promising to be the perfect tool for diagnosing car problems without breaking the bank. My experience, however, taught me a valuable lesson: cheap doesn’t always mean cost-effective, especially when it comes to car diagnostics.
My Journey with OBD2 Scanners: From Basic to Advanced
Initially, I opted for a very basic handheld unit, the Autophix 7610. For simple code reading, it seemed sufficient. It was indeed cheap and did the job of pulling basic trouble codes. However, when I encountered a more complex issue with my car – specifically with the headlights module – the limitations of this basic scanner became apparent. I needed more diagnostic capability.
Seeking an upgrade, I was drawn to the OBD-Eleven Bluetooth dongle. The appeal was strong: wireless connectivity, smartphone app interface, and a seemingly affordable entry price. I even went for the PRO level access, thinking it would unlock advanced features. And it did, to some extent. The OBD-Eleven allowed for more in-depth diagnostics and even some basic programming.
However, the catch with OBD-Eleven, and similar app-based scanners like Carista, is the subscription model. To truly utilize the “PRO” features for coding and more advanced diagnostics beyond just reading codes, you need to pay an annual fee. What initially seemed like a cheap OBD2 scanner option started to look less appealing with this recurring cost. Moreover, in my specific headlight module issue, the OBD-Eleven fell short. It incorrectly diagnosed the problem, suggesting a replacement module was necessary, which would have been a costly and unnecessary expense.
This led me to invest in a Ross-Tech VCDS (VAG-COM Diagnostic System). While the initial outlay was higher than the “cheap OBD2 scanner” category I was initially targeting, it proved to be a game-changer. The VCDS is specifically designed for VAG vehicles (Volkswagen, Audi, Skoda, SEAT) and offers unparalleled diagnostic and coding capabilities. And crucially, it has no subscription fees. Using the VCDS, I was able to correctly diagnose and fix the headlight module issue, saving myself a significant amount of money and frustration.
The Pitfalls of “Cheap” OBD2 Scanners: Understanding Paywalls
My experience highlighted a crucial point about so-called “cheap” OBD2 scanners, especially the Bluetooth dongle type with smartphone apps. Many of these devices operate on a freemium model. The initial cost of the dongle might be low, making them seem like the best cheap OBD2 scanner option. However, to unlock their full potential, particularly for more advanced diagnostics, coding, and adaptations, you are often pushed towards subscription-based access.
These subscriptions can quickly add up, and over a few years, you might end up spending more than you would have on a more capable, albeit initially more expensive, system like VCDS. The constant upselling and paywalls can be frustrating, especially when you realize that basic functionalities are locked behind these paywalls.
Why VCDS is the Best Long-Term Investment for VAG Car Owners
For owners of VAG vehicles who plan to keep their cars for the long haul and are interested in DIY maintenance and repair, the Ross-Tech VCDS is, in my opinion, the best investment. While it might not be the “cheapest OBD2 scanner” upfront, its comprehensive capabilities, lack of subscription fees, and strong community support make it incredibly cost-effective in the long run. It offers dealer-level diagnostics, coding, and adaptation options, empowering you to tackle a wide range of car issues yourself.
Basic Code Readers: When “Cheap” is Enough
Of course, not everyone needs the advanced features of a VCDS. If you simply want a cheap OBD2 scanner to read and clear basic trouble codes, a basic handheld unit or a simple Bluetooth dongle (without paying for subscription upgrades) can suffice. These are convenient for quickly checking engine codes and getting a general idea of potential problems. Just be aware of their limitations when it comes to more complex issues or vehicle-specific diagnostics. And remember, smartphone-based scanners might not work if you are in an area with poor or no internet connectivity.
Conclusion: Investing Wisely in Your OBD2 Scanner
In the search for the best cheap OBD2 scanner in 2017, and even today, it’s important to look beyond the initial price tag. Consider your needs, the type of car you own, and your long-term plans. While truly “cheap” options exist, they often come with limitations or hidden costs like subscriptions. For VAG car owners seeking comprehensive diagnostics and long-term value, investing in a system like VCDS, despite the higher initial cost, is often the most economical and effective choice in the end.
