Choosing the right diagnostic scan tool can be a daunting task for any mechanic. Two popular options are VCDS (Ross-Tech) and Launch. This article delves into a comparison of these tools, based on firsthand experience with various scan tools including Matco, Snap-on, AutoEnginuity, and both genuine and clone Launch devices. We’ll explore their strengths and weaknesses to help you determine which best suits your needs.
A Mechanic’s Perspective on VCDS and Launch
As a professional mechanic working primarily on VW/Audi vehicles, VCDS (Vag-Com) is my go-to tool. Its deep integration with the VAG group vehicles allows for comprehensive diagnostics and coding capabilities unmatched by other generic OBD2 scanners. However, for other makes, especially BMW and Mercedes, the Launch diagnostic platform has proven incredibly versatile. While it may not handle every system perfectly (e.g., X5 air suspension requires an Autel), its coverage for modules like light control modules offers significant value. The ability to program used modules offers a cost-effective solution for both the mechanic and the customer.
The Launch’s wireless functionality is a significant advantage, maintaining a stable connection even in challenging environments filled with heavy machinery. Surprisingly, it also provides decent coverage for older Volvo models (1996-1999) and Jaguar, surpassing even AutoEnginuity and Snap-on in some cases. For domestic vehicles, it handles OBD1 GM and most Ford/Chrysler applications with ease, though Dodge Ram requires a dedicated tool like a Solus or Matco.
Launch: Genuine vs. Clone
The affordability of Launch makes it an attractive option. However, the market is flooded with cheap clones, primarily from Asian manufacturers. While these clones might offer similar functionality initially, there are significant drawbacks. Genuine Launch devices come with user accounts for online updates and support. Clones often piggyback on these accounts, leaving you vulnerable if the seller disappears or support is needed. Repairing a clone can be near impossible.
Performance and Speed
Concerns about the speed of Launch tools are often unfounded. In practice, setup time is comparable to OTC/Solus and significantly faster than AutoEnginuity. Data loading speed is on par with other leading tools. The user experience is generally positive, unlike the frustrating Snap-on Solus, which often lags. A YouTube comparison video by a New York mechanic group further validates the Launch’s performance, especially for BMW diagnostics.
Conclusion: VCDS or Launch?
The choice between VCDS and Launch depends on your specific needs. For dedicated VW/Audi work, VCDS remains the gold standard. However, Launch offers broader coverage across multiple makes, impressive wireless functionality, and excellent value. Be wary of clone Launch devices; the risks often outweigh the initial cost savings. Invest in a genuine tool for reliable performance, updates, and support. If you’re looking for a versatile and affordable scan tool, a genuine Launch device is a worthy contender.
