Best Mercedes OBD2 scanners: iCarsoft MBII, BlueDriver, or FOXWELL NT301?

OBD2 functions and system diagnostics

The iCarsoft MBII, BlueDriver, and Foxwell NT301 can perform all 10 OBD2 test modes. This means they can request powertrain and freeze frame data, conduct O2 sensor tests, read the results of onboard monitoring tests, control onboard systems, clear and reset emission-related data, request vehicle information, and retrieve pending and permanent DTCs. 

The full suite of OBD2 functionalities is useful in checking your engine and other systems and reading data about the glitches and errors that happen to them. 

OBD2 scanners have different capabilities when it comes to the number of systems they can diagnose. While some only diagnose the engine system, others diagnose more systems or all of them. 

The iCarSoft MBII and BlueDriver are powerful system diagnostic devices because they can diagnose every system in your Mercedes vehicle. Foxwell NT301 is the exception here. It can only clear codes, it can’t diagnose any systems. 

BlueDriver’s main advantage is a giant database of millions of past verified repair reports useful for beginners and pros, saving you time and money.
BlueDriver can also locate problems in all other systems including the SRS Airbag system, Steering, and Suspension (SAS) System, Battery Management System (BMS) system, and so on.

Apart from diagnosing the four main engine systems, the iCarSoft MBII and BlueDriver can also locate problems in all other systems. This includes the SRS Airbag system, Steering, and Suspension (SAS) System, Battery Management System (BMS) system, Tire Pressure Monitoring System (TPMS) system, braking system, and other systems. The only difference is that the iCarSoft doesn’t always support all systems in all vehicles.

For that reason, I recommend the BlueDriver to anyone looking for a surefire Mercedes scan tool that performs OBD2 diagnosis and full-system diagnosis.

Advanced service functions

iCarsoft scan tool has 5 advanced service reset functions, BlueDriver has 3 reset functions, and Foxwell NT301 has none.  The iCarsoft MBII scan tool’s service functions include the oil light reset, EPB system maintenance, ETC reset, DPF system maintenance, and SAS calibration. BlueDriver can perform oil light reset, TPMS reset, and battery registration. Foxwell NT301, however, doesn’t have any service functions. 

You should buy the iCarsoft if you want to perform some advanced service functions on your Mercedes.

iCarsoft MBII is an affordable, Mercedes-only scanner that will scan all your systems without the risk of messing up your ECU since it’s unidirectional.

Vehicle coverage

The Foxwell NT301 supports all 1996 and newer cars, light-duty trucks, SUVs, and minivans sold globally, including Mercedes and Sprinter Vehicles. It can also work with OBD1 vehicles from 1994 to 1995 if connected with an OBD1-to-OBD2 adapter. 

BlueDriver also supports all cars and light trucks with the model year 1996 or newer. The iCarsoft, on the other hand, is only compatible with the Mercedes brand, and it supports over 50 models in almost all Mercedes Series as long as it doesn’t use a 38-Pin connector. It also supports Smart models made in 2005 and later.

Weaknesses

iCarsoft MBII is only compatible with Mercedes cars, but it can’t reset the service reminder on all Mercedes models. It also can’t perform programming functions and doesn’t work with pre-1996 models or models with a 38-pin connection. After scanning, you’ll have to write down the resulting fault codes since the iCarsoft MBII doesn’t store them.

BlueDriver only supports Android and iOS phones, so if you have a Windows phone running Windows OS, it can’t support it. It might pair with other apps, but the process is quite tricky to pull off. It could also use some advanced features on top of its already impressive feature set, including ECU programming and bi-directional testing. 

Foxwell NT301 can be a little complicated for absolute beginners. It has poor instructions that can be difficult to follow. The menu takes some getting used to as well, but it is a joy to use once you know your way around it. The device itself could use a case, although the rubber protection around its edges offers some protection.

Best professional diagnostic scanners for Mercedes

Next, we’ll examine the best Mercedes diagnostic scanner for professionals and Mercedes enthusiasts who have some experience with in-depth repairs. These scanners have more advanced features like directional testing and more reset functions. I will compare the top three products in this category and recommend the best one for you.

Best professional scan tools for Mercedes: iCarsoft MB V3.0, FOXWELL NT510 Elite, or Autel MK808BT?

OBD-II functions and system diagnostics

The iCarsoft MB V3.0, Foxwell NT510 Elite, and Autel MK808BT support the main OBD2 protocols like CAN, ISO 9141, KWP 2000, J1850 VPW, and J1850 PWM. They can conduct the 10 OBD2 diagnostic test modes, including reading live powertrain and freeze frame data, clearing emissions-related data, reading pending and permanent trouble codes, etc. Additionally, Foxwell NT510 Elite supports OBD1 protocols.

The same goes for their system diagnosis capabilities. The iCarsoft MB V3.0, Foxwell NT510 Elite, and Autel MK808BT are full-system scanners, so they can check any system in your Mercedes for errors. The list of systems they can diagnose includes, but is not limited to, the engine, HVAC, transmission, electronic, ABS, SRS, TPMS, and exhaust systems.

If those are your needs, you can pick up any of these scanners for in-depth OBD2 and system diagnosis, but I would recommend the Foxwell NT510 Elite.

FOXWELL NT510 Elite
4.1
FOXWELL NT510 Elite is a user-friendly yet powerful tool that performs both basic and special functions to ease your repairs.

Advanced service functions

Autel MK808BT has 25+ service functions, the highest of all the three scanners. It is loosely followed by Foxwell NT510 Elite, which has 15 service functions. Lastly, the iCarsoft MB V3.0 has 11 service functions.  These functions allow you to service and maintain your vehicle on your own, saving you multiple trips to the mechanic and associated costs. 

Autel MK808BT’s service functions include oil reset, EPB reset, throttle reset, Headlamp, SAS reset, Window Door Roof, ABS Bleed, DPF Regeneration, Battery Registration, Injector Coding, IMMO keys for some Asian cars, etc. 

FOXWELL NT510 Elite is a user-friendly yet powerful tool for Mercedes that performs both basic and special functions to ease your repairs.
Foxwell NT510 Elite can perform oil light service reset, ABS service, TPMS service, Diesel Particulate Filter Regeneration, SAS adjustments, EPB service, and so on.

Foxwell NT510 Elite can perform oil light service reset, ABS service, TPMS service, Diesel Particulate Filter Regeneration, SAS adjustments, EPB service, throttle body adjustment, Crankshaft position sensor adaptive learning, CBS condition-based service reset, airbag reset, battery registration, CAS reset, CO adjustment, IMMO keys, and adaptive headlamp reset.

iCarsoft MB V3.0 also has some special functions, including oil light service reset, control service interval reset, DPF Regeneration, battery registration, throttle body adjustment, brake deactivation, EPB reset, fuel pump activation function, air filter self-learning, SAS calibration, and ABS bleeding.

Autel MK808BT delivers multiple advanced functions over a strong Bluetooth connection along with a 1-year warranty.

Coding/programming

Foxwell NT510 Elite only supports injector coding and Autel MK808BT supports injector coding and IMMO key programming, but iCarsoft MBV3.0 doesn’t have any coding or programming capabilities. 

Although they don’t support full coding and programming, Autel MK808BT comes closest.

Bidirectional Testing

The iCarSoft MB V3.0 and Foxwell NT510 Elite both support bi-directional testing, but the Autel MK808BT does not. Bi-directional tests allow you to send commands to vehicle-specific systems, subsystems, and components, as well as read the data generated by those tests. Scan tools that can run these actuator tests increase the repair possibilities of a car compared to other scanners that only read codes. 

I recommend the Foxwell NT510 Elite for mechanics or DIY repairers who want to perform bi-directional tests on all Mercedes vehicle systems.

Vehicle coverage

iCarsoft MB V3.0 is compatible with all OBD2 Mercedes-Benz/Sprinter/Smart vehicles made between 1996 to 2019. 

Foxwell NT510 Elite for Mercedes is updated to support all OBD1 and OBD2 Mercedes vehicles to date. 

Autel MK808BT is only designed to support 80+ American, European, and Asian vehicles, some of which are Mercedes vehicles. You’ll have to message their customer support to be sure that it supports yours.

However, to be on the safe side, you should buy the Foxwell NT510 Elite. It supports the highest number of Mercedes, but you can also check with their customer support just to be sure.

Price range: $177-$187

Weaknesses

iCarsoft MB V3.0 could use more advanced service functions, although the 11 it already has is enough for most users, professionals may be looking for more. It can’t code or program your ECU. As a result, you can’t change key car settings with the tool. iCarsoft MB V3.0 also doesn’t support older models made before 1996. 

FOXWELL NT510 Elite has a lot of advanced reset functions and complete system diagnosis, which is excellent. However, it can only run those special diagnoses on OBD1 and OBD2 vehicles made in 2015 to date. It is also limited in how many cars it can support at once. FOXWELL NT510 Elite only holds up to 5 vehicle models and brands at once. 

Although the Autel MK808BT only supports 80+ American, European, and Asian vehicle makes, it sometimes has compatibility issues with some foreign cars. You get software updates for the first year, but it isn’t free after the first year.

Best Mercedes OBD1 scanners 

If you have an older Mercedes car, all hope isn’t lost. These OBD1 scanners work with any Mercedes vehicles made before the adoption of the OBD2 protocol between 1982 and 1995. Because OBD1 is so dated, these scan tools are primarily OBD2 scanners that can perform OBD1 functions through a 12-pin OBD1 to 16-pin OBD2 adapter. Below is a comprehensive review of the two best Mercedes OBD1 scan tools.

Best Mercedes OBD1 scanner: INNOVA 3120E or INNOVA 3170RS?

OBD1 diagnostics

If you have an OBD1 Mercedes, both Innova 3120E and Innova 3170RS can perform OBD1 diagnostics on your vehicle. With these Mercedes scan tools, you can check your emission systems and clear error codes from the engine system and ECU. The only difference between their OBD1 capabilities is that the Innova 3170RS can read live data from your vehicle in real-time, but the Innova 3120E can’t.

I prefer the Innova 3170RS because it can read live data aside from the usual OBD1 functions.

innova 3170rs
INNOVA 3170RS
4.5
Innova 3170RS doubles as an OBD1 scan tool and a powerful OBD2 tool with in-depth system diagnosis and many codes.

OBD2 test modes

The two devices aren’t built for OBD1 alone. They both support ISO 9141, Keyword 2000, J1850 PWM, J1850 VPW, and CAN networks and perform OBD2 diagnostics to different degrees. For instance, of the ten OBD2 test modes, Innova 3120E only supports 8 test modes. However, Innova 3170RS supports all ten test modes for full OBD2 diagnosis. 

The ten OBD2 test modes include reading live powertrain data, reading freeze frame data, requesting the results of onboard system test and oxygen sensors tests, controlling onboard systems, accessing vehicle information, clearing emissions-related data, and finally, requesting stored, permanent, and pending DTCs. Innova 3170RS can do all the above. 

On the other hand, Innova 3120E can do all that except controlling onboard systems and requesting the results of tests conducted on onboard systems.

The Innova 3170RS is the scanner to buy if you want to run complete OBD2 checks as well.

innova 3120e
INNOVA 3120E
4.6
Innova 3120E reads all possible diagnostics in your OBD1 Mercedes with great accuracy and has a memory back-up for later review.

System diagnosis

Diagnostics devices can pull and clear codes from different systems in your vehicle. Innova 3170RS can scan all your Mercedes vehicle systems for a full system diagnosis, but the Innova 3120E can only scan the Anti-lock Braking System (ABS). Innova 3170RS can diagnose your engine, ABS, SRS, powertrain, HVAC, fuel, chassis, fuel, and other systems.

Innova 3170RS is the obvious choice for system diagnosis.

Advanced reset functions

Innova 3170RS has 8 advanced reset functions, which is a lot more than Innova 3120E that only has one. Innova 3120E can only reset oil lights, but the Innova 3170RS combines multiple maintenance functions. Innova 3170RS does ABS brake bleeding, battery tests/resets, oil light reset, TPMS tests, EPB resets, transmission temperature resets, hybrid battery cell voltage diagnosis, and SAS calibration.

Innova 3170RS is my top pick for advanced service reset functions, and I recommend it easily.

Price range: $271-$281

Vehicle Coverage

Innova 3120E and 3170RS support both OBD1 made between 1982 and 1995, and OBD2 vehicles made 1996 till date. Support for Mercedes on the Innova 3120E is an optional upgrade, but it comes with Innova 3170RS.

The Innova 3170RS is best if you want to use an OBD scanner that natively supports Mercedes.

Weaknesses

Innova 3120E is pretty limited in the advanced features it offers. It is only perfect for beginners or casual users who want to diagnose OBD1 features only. It can’t read live data on those OBD1 cars, but the tests it conducts are good enough. When it comes to OBD2 cars, Innova 3120E can only perform 8 of 10 test modes, and it can’t show live data graphs as well. You can’t use Innova 3120E for advanced diagnostic of non-OBD2 protocols, as it isn’t an all-system scan tool, and it only has one reset function.

Innova 3170RS has a lot of great features, from system diagnostics to advanced system functions, but it does not support bi-directional testing and actuator tests. This means you can’t diagnose your vehicle by activating different parts in real-time, such as the wiper, door locks, etc. Also, Innova 3170RS can’t code or program your vehicle’s ECU.

Best Mercedes diagnostic software: StarCOM 

OBD-II functions and system diagnostics

StarCOM supports K-Line multiplexor, CAN-BUS interfaces, and SAE J1850 bus (both PWM and VPW). With that, it can perform all ten OBD2 functions seamlessly on any Mercedes. The team behind the software is also actively working to improve its live data logging capabilities. It can do everything from reading codes to clearing DTCs, requesting onboard system test results, controlling onboarding systems, and other much-desired OBD2 functions.

Speaking about onboard systems, StarCOM can perform system diagnostics on every single system in your Mercedes vehicle. It offers manufacturer-level diagnostics to further improve your car system for optimum performance. 

Advanced service functions

This is another area where StarCOM excels. It offers over 50 service functions to help you maintain your car. In the engine system alone, it offers DPF reset, EGR valve reset, zero quantity calibration, engine idle speed test, and 8 other functions. For Mercedes with convertible top, it offers rain sensor test and panoramic sliding roof calibration.

Coding/programming and bi-directional testing

StarCOM software supports coding and programming on Mercedes vehicles. It allows you to program configurations to your control unit and through its customer support, you may be able to write configurations to read-only ECUs. It also supports coding in some electric/hybrid vehicles. Additionally, it can activate actuators for bi-directional testing. This means you can control the actuators from the software to test for issues during operation.

System requirements and connection cable

StarCOM works on Windows Vista, XP, 7, 8, or later. Its easy-to-follow installation process is detailed in the software manual. It also supports GNU/Linux systems. You’ll need a Linux 2.6+ with USB support, USB CDC driver, and Wine 1.0.1 or newer, since the program was created through Wine. In both cases, you’ll directly connect the StarCOM interface to the OBD2 connector. 

Vehicle coverage

StarCOM is made specifically for Mercedes and Smart vehicles, so it works on all OBD2-compliant Mercedes vehicles from 1996 till date. It also has some useful functions for some of the electric and hybrid vehicles. 

Download: obdtester.com/starcom

Weaknesses

StarCOM only supports Mercedes vehicles made after 1996, which leaves out the many models made before in and before 1995. Essentially, it doesn’t support OBD1 vehicles, but it would have been great to see some OBD1 features on such a powerful scanner. StarCOM is also only available to Windows users because the developers don’t have a version compatible with macOS. Windows users must install the latest service pack to use the software. The developer’s website and manual could use more regular updates, so new users can navigate them easily.

Final thoughts

Diagnostic scanners are a must-have for everyone who owns a Mercedes. They save money on repairs and time waiting on your mechanic. Regardless of your experience with them, there is a diagnostic scanner that you can use to get the results you want.

5 Steps To Choose The Best Mercedes Scan Tools

Step 1: What scan tool brand should I go for?

There are three major dominant brands for Mercedes Benz: iCarSoft, Autel, and Foxwell. Below I have put together a short introduction and information analysis of each of these three leaders.

iCarSoft

iCarSoft is a provider of executive indicative equipment for a range of different motorized vehicles. They are the first on the planet to hone in on unique brand DIY analysis equipment using multiplied systems, computed software design, and testing the performance of vehicles.

Step 2: What type of scan tool suite me?

Are you a regular Mercedes Benz owner? Or are you an enthusiast or automotive vehicle technician?

This question will determine which kind of scanner is best suitable for you.

If you are just an ordinary owner who wants to get into the nitty-gritty of motor repairs or someone who likes only to do it themselves, then a standard code reader will be more than enough for you to get started with. Using an ordinary code reader will give you a whole range of functions needed to diagnose your vehicle. For example, you may need to reset your TPMS (Tire Pressure Monitoring System) or put out your CEL (Check Engine Light) or MIL (Malfunction Indicator Light).

Also, you will be able to do the obvious things like:

  • reading and clearing diagnosing trouble codes that cause your EML (Engine Management Light) to come on,
  • locating faulty sensors, and checking things like your fuel pressure, air intake,
  • checking your VIN, or
  • finding out your wheel speed when they are in rotation via the wheel speed sensors.

A good entry point for you to embark on your journey as an analyzer would be Foxwell NT301. This code reader can do all the tasks mentioned above, plus many more, including reading freeze frames and live data, checking graphs, and carrying out evaporative emission control system tests (or EVAP for short).

If your knowledge advances those of the everyday customer or regular car DIYer, and you insight some technical experience towards motor vehicles, let’s say you are an enthusiast or a mechanical technician. Unquestionably, you will look for a connotative communicator that gains more ground, keeping the tires on the road kind of deal.

You will have full access to all systems, get into the vehicle’s internal organs, the modes and moderations of the ECU, and delve into ABS, airbag system, Lighting Systems, Fuel, or Transmission systems, etc. This enables and authorizes you to read and clear enhanced technical codes. Examples of this kind of system checking scanning tool would be either the iCarsoft I980 or the Autel MaxiLink ML629.

Another example of a useful utensil that accompanies you with these advanced service functions is the iCarsoft MBII. With this, you will come into contact with systems and carry out special service functions such as SAS (Steering Angle Sensor), EPB (Electronic Parking Brake). If your vehicle has an electronic parking brake, you will need this kind of DTC reading tool to rewind the pistons in your calipers without any damage! I have seen somebody try to do this manually, and the piston pops out of the caliper. Trust me, it is messy and not an easy thing to pop it back in!

iCarsoft MBII is the Mercedes Diagnostic Tool works like a charm since it supports a wide variety of functions.
iCarsoft MBII help user come into contact with systems and carry out special service functions such as SAS (Steering Angle Sensor), EPB (Electronic Parking Brake).

So keep yourself clear by knowing which scanner is best fitted to your vehicles and your needs.

Step 3: Is my Mercedes covered?

When considering compatibility and vehicle coverage, you should be aware of the enhanced available features of Bluedriver; some may only be available for specific makes and models; conversely, other features work healthily with any car that has an OBD2 port. Please make sure to follow up on the advanced features before buying your desired instrument.

An additional example will be if we talk about the iCarsoft MBII and the iCarsoft I980. In the light of compatibility, these two diagnosable contraptions are compliant with Mercedes models from 2005 to 2014. If you are an owner of a more modern model or a model of the previous years, please be aware that you will have to contact the company to check that your vehicle is accommodating to the code reader. It would be best to note to acquire information about this dilemma before you purchase the scanning implement.

Step 4: Should I buy something pricey?

So here comes the question we all dread! How much should I expect to spend? Well, this depends on your current skill level when it comes to vehicle diagnostics. If you are only a novice badge holder, then your sacrifice will not be too high, as you will only need to use the fundamentals. Yet, with essential features, your expenditure will be around the price point of 50 to 100 dollars. Not too bad, ey!
