MB V3.0 for Mercedes-Benz/Sprinter/Smart Diagnostic Tool with auto VIN/Quick Test

Scanner did exactly what it was supposed to do. I had a minor problem finding my vehicle (2016 Metris) I emailed Barnett at tech support and he got back to me within a couple of hours with information on where my vehicle was located. I was able to scan and reset an air bag light that everyone said the vehicle had to go to the dealer.

This diagnostic scanner was shockingly better than I expected. The price is amazing and I was worried I was going to get a knock off or something that didn't work but I was pleasantly surprised. It dies everything it advertises. I was able to get my mercedes 2009 c300 4matic sport out of limp mode which is where it won't shift out of 1st gear. My car was basically unusable and this scanner allowed me to delete the diagnostic codes that were causing my car to be in limp mode and causing my engine light to be on. It was super easy to use. You just plug it in to your obd port and it's ready to go. Quick, fast, and easy. I'm no mechanic and I fixed my car all by myself. If you own a Mercedes you should own this scanner. It's worth every penny.

This scanner never worked. I would plug it onto the OBD port ans all the button did not function. This item was nothing more than a expensive paperweight. I sent an email with pictures of the non-functioning screen and the serial number. to no avail. I resent all my infor to iCarsoft and a CSR named Bruce Lea, and he told me to format a memory car in FAT32. I omly have MAC computer and no PC's.. I offered to retun my mom-functioning device for a new one that works as the 1st one I PAID FOR shoud have, Still no answer, This device is NOT RECOMMENDED

If you run the quick test, it will launch into a long stream of tests and may be doing things to your car you didn't anticipate of don't understand. At one point it set my instrument display into a mode where it was repeatedly beeping and wouldn't stop. It has been a couple months now so am recalling this from memory, but I had to do a clear faults, possibly clear all faults and let it just run and by luck it cleared the alarm. So, one has to be very careful to just turn this thing loose running all diagnostics. However, I purchased it to allow accessing the transmission computer module and was able to do so. I could see the internal transmission fault codes and once I repaired the problem by replacing the transmission shift lever module, I was able to clear the transmission fault codes. I was able to view live data. The transmission solenoid test was not clear. I ran the test and it comes back almost immediately that test ran successful. That is ambiguous. So the test ran successful; does that mean the solenoids were all ok or the just that the test ran to the end? I heard no clicking of solenoids and the instant end of the test made me doubt whether it tested anything. There needs to be explanations of what each test is actually doing. I didn't check but doubt that's on the web site. The quick test needs to allow halting the test after each module. Since this is on sale for the average mechanically inclined, but NOT an expert Mercedes specialist like me, it should be much more informative, user friendly, and less operating in the dark. Also, to get started, one has to enter the VIN. The device reads the VIN and you don't have to type it in. However, one has to repeat that each time. Can it not store the VIN at least during the session and reuse it each time so you don't have to keep passing through those entries?

I previously had a bluetooth OBDLink MX+ which is just a little cube. It was supposed to cover a bunch of protocols but it only provided Engine/ECU codes for my Mercedes E350. Disappointing. This iCarsoft MB V3.0 is super cool. I did their firmware upgrade before I tried it out and that went just fine. The upgrade was easier to do than PDF showed, it's pretty intuitive. Using the MB V3.0 is a snap, the auto VIN worked great and the quick scan pretty much does it all. My car has a power driver door lock that isn't working and that showed a code, what's more the MB V3.0 has a feature that signals the Door Control Module to test the driver door lock actuator (and the others individually too). Such a powerful tool. It seems you signal any actuator, as I did this for the AC Divider Flap. For that you can see the current position and more. Clearing codes individually is also simple to do and codes are labeled as "historic" or "historic, present" where historic codes are not a problem at the present time. During the car's battery change many modules had reported "voltage too low" which was true for just that moment in time, so that's one example of historic but not present. It might have been nice to use an iPad and BT but wired shows data immediately, way faster than the BT dongle thing, and the wire really is not a problem for me. This MB V3.0 tool is keeper for me, it works great and it has features that really help find and test problems.

I gave this scanner 3 stars because it does work (to an extent) without the user being an expert, like you would if you used a sophisticated factory scanner like MB Star Das/Xentry system. The problems with this device are many, but I will list just a few. 1). The scanner would not identify my vehicle or its VIN as advertised. (2006 Mercedes SL500 R230). I had to go thru the drill down list each and every time I used the tool. This included entering the make, the model, the series, and the year. My cheap $39 Harbor Freight code reader recognizes the VIN immediately. 2). Once I got the scanner to recognize my vehicle, the next step in the diagnostic section would be to perform the “quick test”. The scanner should automatically go thru and check for codes on all the modules on the vehicle. On my vehicle, I think there are 35 different modules this device interrogated. (there are more than 35 on this vehicle). Every time I tried this the scanner would go thru 10-15 modules fairly quickly, then it would start to slow down taking longer and longer with the later modules. Finally it would hang forever on a module like “Cell phone interface” which is an option my car doesn’t have! After waiting for 10 minutes, the scanner remained frozen until I unplugged the OBD cable. Then you have to do the entire process over, starting with the manual VIN entry. 3). Due to the scanner tending to freeze, I would simply have to interrogate each module individually and avoid the modules that tended to hang the system Very time consuming and inconvenient. 4). Once you did get the module info, the data was limited. In my case, I was interested in the Transmission Control unit. The “read-data” menu option leads you to several sub-menus that are clumsy to use. The screen only shows five lines of data at a time. Good luck with tracking data in a sub menu that has 7 or 8 lines of data. You are forced to flip back and forth between screens. Many of the data sub menus have redundant data lines like Trans oil temp. There is no option to custom pick and choose which data you want to monitor. 5). Data logging is hit and miss, at best. I did a test run trying to monitor some shift data on the TCU. Of course, the data you monitor is only the data that the sub menu prescribes. If you want more data than what the sub menu offers, you must do multiple logging sessions. This method has obvious limitations. It only records data once every second. On several logging runs, I examined the data afterwards, only to find that the 10 minute run record showed the exact same numbers for the entire 600 frames. Absolutely useless! I did manage to get one out of five sessions to actually record dynamic data. 6). On the box, they advertise that the scanner will do transmission adaptations. When I selected that option, the scanner informed me OPTION NOT AVAILABLE FOR THIS VEHICLE. Just for fun, I tried a variety of other models and years. In every case, I got the same OPTION NOT AVAILABLE FOR THIS VEHICLE. So my guess, it will not do transmission adaptations on any Mercedes. False advertising, for sure. All in all, don’t waste your time or money with this scanner unless you only want a clumsy, expensive, glorified code reader. When it comes to Mercedes, either spend the money on a real DAS/XENTRY system or go with the cheap Harbor Freight code reader. This device is an amateur “in-betweener” and is way overpriced for what it will do.

My husband needed this item to check for what issue his vehicle might be having. He has used it numerous times since purchasing and it works as described and he is happy with it.

This is a fantastic tool for the tech savvy Mercedes Benz owner. There are even activated tests you can run. So much more than just reading a code. It allows you to initialize specific modules in the order you want/need to systematically troubleshoot what or where the actual problem is. Best money I have ever spent on a diagnostic tool.
