AutelOBDII OBD2 Code Reader Diaglink (DIY Version of MD802) All Systems/Modules Diagnostic for ABS, SRS, Engine, Transmission, EPB, Oil Reset

I have a box full of scanners, bluetooth OBD plugs and a laptop full of both OEM and aftermarket software. All of them fill a need and some can do far beyond what this scanner can do, BUT they are a PITA to use or very limited compared to what this unit does.I got this because my E39 has an intermittent no crank start problem. I did a bunch of old school electrical testing and the problem remained elusive. I got this unit, downloaded the BMW module and plugged it in. I saved and cleared a boatload of codes (sort of normal for a 17 year old car) and set about looking at the immobilizer module. I go in and click on about 5 items having to do with the key codes and starter inhibit values and I'm off to the races. The first day the car starts every time so since this doesn't draw much power I leave it plugged in. The next day it says no communications but I can quickly select my 5 items again and it's ready to monitor. The second start attempt I see that the key ID is correct (key 7) but it's code is not OK so the starter is inhibited. I grab another key (3) and the car starts right up. Turn it off and put the first key (7) in and it starts. So I know the problem is in the immobilizer key code process and not something like wiring except possibly the antenna coil. It may be the easy fix is to remove the key completely and far enough away for it to be re-recognized when it is re-inserted or maybe have two keys or remove the chips from the keys and keep a couple of chips around. Still too soon to tell. Apparently if you try a bad key code several times the immobilizer shuts the start process down for a period of time. Trying to troubleshoot this without the insight to the immobilizer values was maddening. Now it's just a matter of figuring out what sequence of events causes the no crank condition. Leaving a laptop up and running for the time periods involved would be very difficult and might result in a broken window and a stolen laptop!Well done Autel!

It doesn't come with instructions for using the product if a regular person ordered this product they would not know how to use it ...

I've been waiting a while to review this! I decided to buy this when my WIFI OBDII dongle started acting up, but was hesitant on choosing this over the higher-priced version that included the data packages for all vehicle makes. It's one of those things where you try to think ahead to which buddies or family members are going to ask you for car help one day, and when you'll need a scanner that works with their car.But then, I realized I'm a Nissan guy. And then rest of the family is either Hyundai, Kia, or VW. I figured the cost of the scanner plus 2 more data packages (1 comes free) that covered all of our cars and trucks (7 to be exact) was a bit cheaper than the full-data version. So, I bought this version.The scanner came nicely packaged, and it just seemed like a very professional tool. I was pleased by that. I started the software install on my Windows 7 machine, and from there didn't have a very pleasant experience. My computer didn't seem to have a suitable driver, and the application looked a little antiquated, and could access the scanner. Now, to be clear, my career has been in computer/IT, so setting up and troubleshooting this stuff is trivial to me. I fussed with it for about 2 hours and had grown tired of the effort, but was still determined. After reading through some other Amazon reviews, I found the best advice: use an external USB card reader for the microSD card. (I realize not everyone probably has one of these!). The software recognized the card, and the Autel application loaded successfully! From there, there were already product updates, and those product updates seemed to fix all my previous issues. Thumbs up!I 'purchased' my free vehicle pack for Nissan, which included Infiniti models, too. I have an 04 Pathfinder and a 98 Frontier, and was particularly interested in checking the ABS codes for both vehicles, and specifically for cycling the solenoids on the ABS module. Unfortunately, the ability to use these particular diagnostic modules depends on the vehicle, which don't support those, but it does have some other useful parts (for instance, real-time monitoring of ABS speed sensors). So, that was a bummer, but realistically not a limitation of the tool, but instead of the vehicle age. Not a big deal, though, since I can pull specialty codes manually from the vehicle, but this scanner definitely compliments that info.I did explore all the functions for the Nissans, and was pleased by the unit. Maybe a little sluggish as it sweeps through systems, but was thorough enough for my needs. At that point, I downloaded the Kia and Hyundai package (again, one data package includes those for both makes) and tested on my 11 Sorento. Being a newer vehicle, it supported a few more diagnostics features of the tool, and I was pleased with that.The real test was for an 06 VW Touareg, which I was troubleshooting a terrible misfire for. Interestingly enough, the VW data package included Bentley, Bugatti, Skoda, Audi, and SEAT vehicles...not that I'll ever work on those vehicles. Not only could this read all the OBDII codes, but it could diagnose every electronic system on the Touareg...yes, it can tell you what the status is of the buttons on the power seat, if you really want to know. I used it to read diagnostics of the headlight system. While I've not personally used the VW VAG-COM diagnostic tool, I imagine this is probably a very capable substitute for it. For sure, this is both cheaper and not some bootleg. For troubleshooting the misfires, this was able to display real-time misfire data (cylinder, counts) and several other user-selectable data monitor points, like timing advance, various temperatures, RPM, etc. Definitely came in handy for this vehicle issue. For this particular vehicle, it was able to read and reset the status for various systems: steering, brakes/ABS, transmission, transfer case, lighting, climate, seats, and a few others.Bottom line is that I found the unit to be quite capable. Your particular vehicle will determine how much functionality is available. I think if you have more electronically-advance cars, this will be more useful for testing and resetting non-OBDII systems. It has other functionality that my vehicles don't have (resetting the engine oil maintenance light, for example), but appears to be a very well-rounded unit. Purchasing the additional vehicle packages was very easy. The Autel software application has seen some significant updates since purchasing, and those updates have definitely improved the interface and speed of the application. At this point, I do not need to use the microSD in a card reader; it works just fine with the included USB cable. If it weren't for the initial setup issues, this would probably be a 5-star unit, but consider it somewhere closer to 4.5 stars.

Received this scanner the other day, and was really excited to try it out when i got back from a business trip...After un-boxing the scanner I tried to plug it into my computer and noticed that the USB connection to the device was very loose and wiggly, "It was Broke to be blunt about it.." So since the USB connector on the device was broke i already knew this was going back for a replacement. However since I had it, I figured I would go ahead and download the install drivers and update the Scanner. I provided my credentials to the main web page and downloaded the update App to my Laptop. I navigated to the Update Icon on the scanner and selected it to update the unit. So after a few minutes i noticed the scanner still had the USB connection window up basically showing me that it was connected to USB. I then realized it had been setting there not doing a thing, so i re attempted to update the scanner, which this time a window popped up asking for me to install the micro SD card and to provide the registration number into a box that clearly was grayed out. So after 4 attempts I gave up. The scanner i received ended up having multiple defects with it. It had a loose USB connection that fell off when i removed the cable, the scanner did not see the Micro SD card it had pre installed in it, & the device would not update or communicate at all with none of the 3 PC computers i have. So as for now this device is not shaping up to be a good device. I am going to ship this back & see about having this replaced ASAP. If the next device works I will provide a updated review. Crossing my fingers and hoping that the next one I receive from this seller does not have a handful of issues like this one does
