Mercedes OBD2 Scanner Comparison Table (2025)
1.FOXWELL NT710 for Mercedes-Benz
I’ve used the NT710 on both my E-Class and Sprinter, and it honestly feels like dealer-level power packed into a slick touchscreen tool. With a 5.5″ HD display, built-in Wi-Fi, and Android 9.0, it boots fast and handles full-system scans without lag. I loved how it reads every module—engine, air suspension, TPMS, even the fuel pump—and lets me run active tests like toggling the fan or triggering the windows. It performs exactly like some of the best bidirectional Bluetooth OBD2 scanners I’ve tested. It’s saved me hundreds in garage visits already, especially with its 30+ service reset options built in.
Features
- Full-system diagnosis for 20+ modules (engine, SRS, ABS, TPMS, etc.)
- Bidirectional control (active tests for windows, fans, mirrors, etc.)
- 30+ service functions: DPF regen, battery registration, SAS reset, oil light reset
- 5.5″ touchscreen (1280×720), Android 9.0 OS, 32GB storage + 4000mAh battery
- Supports all 10 OBDII modes (live data, EVAP test, freeze frame, etc.)
- Auto VIN detection, Wi-Fi updates, and printable health reports
What Works?
The live data graphs helped me track sensor failures in real time. I ran active tests on the sunroof and cooling fan, which saved time and narrowed down the issue fast. I also completed an air suspension reset on a 2016 GL450 without needing a trip to the dealer.
What Doesn’t Work?
Some older models (pre-2000) don’t support all functions even after updates. The interface can feel slightly sluggish if you don’t update it regularly. Also, it only comes with one Mercedes software license—you’ll need to pay extra for other brands.
Who Should Buy This?
If you own a Mercedes from 2000 or newer and want pro-level diagnostics without visiting a shop, this tool is gold. It’s perfect for DIYers, small shop owners, or Benz enthusiasts who want full control. If you value bidirectional testing and live data in a single unit, the NT710 is 100% worth it.
2.iCarsoft I980 – Best Entry-Level Scanner for Mercedes
I picked up the iCarsoft I980 when I needed something simple, fast, and Mercedes-specific. For a scanner under $100, it impressed me with its ability to read and clear codes from major systems like the engine, ABS, airbag, and transmission. It’s definitely not loaded with advanced features, but for basic use—it gets the job done. It reminded me of a few picks I saw among the best OBD2 scanners under $50—basic, reliable, and built for quick scans. I tested it on a 2014 C-Class and a friend’s ML350, and it connected within seconds.
Features
- Reads & clears codes on full systems (engine, SRS, ABS, transmission)
- Supports 10 OBD II/EOBD test modes: CANBUS, ISO9141, KWP2000, J1850
- Live data stream + freeze frame + O2 sensor + EVAP test
- Compatible with all OBD II-compliant vehicles
- Lifetime free updates via USB 2.0
- One-year warranty, multilingual support
What Works?
It pulled ABS and airbag codes from both my C-Class and a Sprinter without any hiccups. The live data loaded quickly, and I was able to reset a check engine light in under a minute. For something this small and affordable, it gives surprisingly accurate feedback.
What Doesn’t Work?
It doesn’t support any service resets—no oil light, no EPB, no SAS. The display feels a bit outdated, especially compared to tablet-based scanners. And if you’re dealing with more complex modules or coding, this won’t cover it.
Who Should Buy This?
If you drive a Mercedes and want a plug-and-play tool to handle basic diagnostics, this is a solid starter. It’s ideal for DIYers who don’t need reset functions but still want real-time data. Anyone looking to stay under $100 and avoid trips to the mechanic will appreciate this.
3.iCarsoft MB V2.0 — Best for Full-System Access on Mercedes
I tested the iCarsoft MB V2.0 on my 2013 E-Class and immediately saw the depth this tool offers. It scans over 650 systems in Mercedes alone—including things like TPMS, Parktronic, suspension, and ignition modules. I didn’t just read codes—I could run full resets, calibrations, and even battery tests. It reminded me of the kind of access I had when testing tools on BMWs in this OBD2 scanner guide for BMW. It felt like having dealer-level access in my own garage, and the updates come free for life.
Features
- Full-system diagnostics: 650+ modules on Benz, 286 on Sprinter, 71 on Maybach
- 9 reset services: Oil, EPB, ABS Bleeding, TPMS, Injector Coding, BMS, DPF, ETC, SAS
- Auto VIN & full OBD2 functions including freeze frame, live data, CVN/VIN read
- Real-time battery voltage monitoring & BMS recalibration
- Works on Mercedes, Maybach, Smart, and Sprinter models from 1996–2023
What Works?
It scanned over 60 systems on my E-Class without a hiccup. I was able to recalibrate the steering angle sensor, reset the EPB, and run an injector test all in one session. The live data graphs were clear and helped me catch a fuel trim issue quickly.
What Doesn’t Work?
Not all features are universal—some functions depend on your exact model and year. You’ll also need a separate 38-pin adapter for older Benz models like W202 or W210. The screen isn’t touchscreen, so navigation can feel a little outdated.
Who Should Buy This?
If you drive a Benz and want pro-level diagnostics without relying on a mechanic, this tool is for you. It’s ideal for DIYers who want to do oil resets, BMS tests, or read hidden modules themselves. I’d especially recommend it for anyone working on multiple Mercedes vehicles.
4.iCarsoft MB II OBD2 Scanner — My Go-To for Mercedes
I’ve used the iCarsoft MB II on everything from a Sprinter to my old E-Class, and it’s easily one of the most reliable scanners I’ve tested for Mercedes. It doesn’t just scan the engine—it taps into the transmission, ABS, SRS, and even weird stuff like AC and window modules. What really sold me was the reset capability. I’ve used it to clear oil lights, reset the EPB, and even run injector coding. It reminded me of a few tools featured in the best Bluetooth OBD2 scanners for 2025 list—versatile, easy to update, and packed with functions. Once I realized it came with lifetime software updates and worked on nearly all Benz and Smart models after ‘96, I stopped looking for anything else.
Features I Use Regularly
- Full-system scans for Mercedes, Sprinter, and Smart
- Includes 7 resets: oil, SAS, EPB, ETC, DPF, injector, ABS bleed
- Works with OBD2 on other brands (engine only)
- Live graphing, freeze frame, VIN reading, and emissions readiness
- Supports most post-1996 models
- Comes with lifetime software updates and hardware repair support
What Works?
It reads deep codes my cheap scanner couldn’t even touch—like airbag faults and transmission issues. I reset my oil light after a DIY change, and the EPB function saved me a trip to the shop. The live data streams were smooth, and I could graph everything in real time during a test drive.
What Doesn’t Work?
Some older models need a 38-pin adapter, and that wasn’t included in the box. A buddy tried it on his early 2000s CLK and couldn’t access all the resets. The interface is a little clunky at first, but I got used to it pretty fast.
Who Should Buy This?
If you’ve got a Mercedes and want to handle your own diagnostics, this thing is gold. It’s ideal for DIY folks, home mechanics, or even indie shops that deal with Benz models often. If you’re tired of “one-size-fits-all” scanners that barely scratch the surface, this one goes deep.
5.CGSULIT SC530 Pro OBD2 Scanner for Mercedes Benz
I got this scanner expecting basic diagnostics—but it really surprised me. For just around $115, it offers OE-level scans across all major Mercedes systems and over 20 reset services. I tested it on a 2015 E-Class and a 2019 GLE; both worked great. Setup was quick, and the AutoVIN grabbed all the car info instantly. It performs like tools you’d expect to see in the best professional car diagnostic tool category. Plus, the free lifetime updates mean I’m not stuck with outdated software.
Features
- Covers all systems: Engine, ABS, SRS, Transmission, BMS, Fuel, Suspension

- Supports AutoVIN with deep module detection
- Free lifetime updates – no subscription or registration needed
- Fast scanning speed, enhanced hardware
- Compatible with most 1996–2025 Mercedes-Benz models (except Sprinter/Smart/38-pin for now)
What Works
I saved around $130 avoiding the dealership for an ABS code reset. It reads deep systems—like body and chassis modules—that most generic tools miss. I also love that updates are free forever, so I don’t get nickeled and dimed later.
What Doesn’t Work?
It won’t connect to Sprinter, Smart cars, or 38-pin models yet, which is kind of a letdown. There’s no bidirectional control like active tests. And while it’s fast, the interface still feels a bit basic compared to tablet-style scanners.
Who Should Buy This?
If you drive a post-1996 Mercedes (except Sprinter/Smart) and want real diagnostics for $115, this is a win. It’s great for DIYers who want to reset warning lights and do basic repairs at home. I’d recommend it if you’re tired of paying shops for stuff you can fix yourself.
5 Buying Guides for Best OBD2 Scanner for Mercedes
1. ✅ Make Sure It Supports Full-System Diagnostics
I learned this the hard way—many cheap scanners only read engine codes. With Mercedes, you need access to ABS, SRS, transmission, and even suspension. I now always look for “all-system coverage” or OE-level diagnostics before buying.
2. ⚙️ Check for Key Reset Functions (At Least 10+)
If you’re doing oil changes, brake jobs, or battery swaps at home, reset functions matter. I always check that the scanner includes things like oil reset, EPB, SAS, and throttle relearn. Anything with fewer than 10 service functions isn’t worth it in 2025.
3. 🧠 Look for AutoVIN and Module Detection
I prefer scanners with AutoVIN—it saves time by pulling up your car’s info instantly. Bonus if it also detects individual modules like BMS or TCM. Trust me, this feature makes diagnostics smoother, especially on newer Mercedes models.
4. 💸 Don’t Get Trapped by Paid Updates
I avoid scanners that charge for updates or require subscriptions. In 2025, there are plenty of great tools—like CGSULIT or iCarsoft—that offer lifetime updates free. Over time, that saves you hundreds.
5. 🚫 Know What It Can’t Do (Before You Buy)
Before grabbing any scanner, I always check the “not supported” list. Some tools still don’t support Sprinter vans, Smart cars, or bidirectional controls. If you own one of those or need active tests, double-check compatibility first.
Final Thoughts: Best OBD2 Scanner for Mercedes
After testing these scanners on multiple Mercedes models, I can honestly say not all tools are created equal. Some just read engine codes, while others dig deep into every module. For me, having something that can reset ABS or throttle after a repair is a game-changer. If you’re tired of overpaying at the shop, investing in the right OBD2 scanner will pay for itself fast. Just make sure it’s Mercedes-compatible, updateable, and built for more than just basic code reading.
FAQs: Best OBD2 Scanner for Mercedes
❓Will Any OBD2 Scanner Work on a Mercedes?
Not really. I’ve tried generic ones that couldn’t read anything beyond engine codes. Mercedes systems are more advanced, so you need a scanner that supports full-system access—especially for ABS, SRS, and transmission modules.
❓What’s the Difference Between Full-System and Basic OBD2 Scanners?
Basic scanners only read engine trouble codes (like a check engine light). Full-system scanners, like the ones I use, go deeper—reading data from brakes, airbags, battery systems, and more. That’s crucial for Mercedes diagnostics.
❓Can I Reset Warning Lights Myself with These Scanners?
Yes—if the scanner supports service resets. I’ve used mine to reset oil change reminders, clear SRS faults, and even perform throttle relearns. Just make sure the tool lists those reset features for Mercedes.
❓Do I Need to Pay for Software Updates?
Most good ones don’t charge. Tools like the CGSULIT SC530 Pro and iCarsoft MB II offer free lifetime updates, which is why I recommend them. Some high-end brands charge yearly fees, so always double-check that before buying.
