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

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.

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.

Screen flickers now, device sropped working, even after I Updated it. Only used for around 15 to 20 times in 2 years to just read codes. Never EVER detected the VIN for 2003, 2005, 2006, or 2008 Mercedes passenger cars.Very bad quality. Not worth the money.

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 was receiving the visit workshop message on my car, which is not a normal error so I wasn't sure if it would pick up anything. This pulled a fault that got me looking in the right place. Fixed the issue then used it to clear the fault. For awareness, the tool is cheaper than the local dealership visit. Happy with this purchase.
