Car repairs can be unpredictable, inconvenient, and costly. But what many drivers don’t realize is that a large part of those costs comes not from the repair itself—but from the diagnostic process. Every time the check engine light turns on, a trip to the mechanic often starts with a diagnostic fee and can sometimes lead to misdiagnosed parts being replaced unnecessarily.

That’s where owning a professional-grade code reader like the VDIAGTOOL VD70S makes a significant difference. Whether you’re a DIY enthusiast or a seasoned technician, having your own diagnostic scanner puts control back in your hands—and your wallet.

Skip the Guesswork with Full-System Diagnostics

Most basic OBD2 scanners only access engine-related codes, limiting your view of what’s really going on. The VD70S takes things much further by providing full-system diagnostics—this means you can scan the engine, transmission, ABS, SRS, BCM, and more. This is critical because many seemingly unrelated problems are interconnected. For example, a bad ABS sensor could trigger a check engine light due to data conflicts with the ECU.

By reading and understanding DTCs (Diagnostic Trouble Codes) across all systems, you avoid relying on incomplete information. You’ll know exactly which components are involved, how serious the issue is, and whether it requires immediate attention. Instead of replacing parts based on speculation, you get accurate insights before committing to a repair.

Save on Diagnostics with Real-Time Data and Bi-Directional Control

One of the standout features of the VD70S is its bi-directional capability. This allows the scanner not only to read data from your car, but also to send commands back to it. For example, you can activate the radiator fan, open EVAP valves, prime the fuel pump, or cycle the ABS pump for brake bleeding—all without touching the vehicle’s controls.

Why is this important? It allows you to test components directly, verify operation, and identify root causes without dismantling anything or replacing parts blindly. If your fan won’t turn on, send a command—if it spins up, the fan is fine, and you can look elsewhere, like the relay or coolant temperature sensor.

Combined with live data streaming, you can observe values like oxygen sensor voltage, fuel trims, MAF readings, coolant temperature, and throttle position in real time. These are exactly the tools professional mechanics use to interpret engine behavior and diagnose accurately—and now they’re accessible to you.

Reduce Repair Bills and Regain Control Over Maintenance

When you understand your vehicle’s condition, you make smarter repair decisions. You’re less likely to fall for unnecessary upsells, and more likely to resolve simple issues yourself—like a loose gas cap, faulty EGR valve, or failing ignition coil.

The VD70S doesn’t just save you from diagnostics fees—it also protects you from expensive guesswork. Replacing parts based on trial and error can cost hundreds or even thousands. With this scanner, you can perform targeted diagnostics, verify repairs, and even reset adaptation data after part replacements.

In the long run, that means fewer shop visits, lower labor costs, and a better-maintained vehicle.

Final Thoughts

Professional-grade scanners like the VDIAGTOOL VD70S are no longer limited to dealership mechanics. With a user-friendly interface and broad vehicle coverage, this tool empowers car owners, small repair shops, and advanced DIYers to take control of diagnostics and repairs.

Whether you're maintaining your family sedan or managing a small fleet, the VD70S helps you save money, reduce downtime, and stay ahead of costly surprises. If you're serious about understanding your vehicle and maximizing repair efficiency, investing in a powerful code reader like the VD70S is a decision that quickly pays for itself.
