AutelAutoLink AL519 Car OBD2 Scanner, Classic Enhanced Mode 6 Engine Fault Code Reader OBDII CAN Diagnostic Scan Tool, One-Click Smog Check, DTC Look, Upgraded of AL319

Saw a good review on YouTube and decided to try it it's a great scanner for the price

Have to smog a vehicle (its been a while since I've done that) and my Bluetooth adapter finally died. I was looking for a complete all in one so I didn't have to link it up and mess with the adapter, this scanned both vehicles and quickly connected to live data and IM's readiness. The user interface is really slick, and easy to read on the color screen. I remember when this level of functionality was way pricier! Didn't even have to look at the manual or look up codes they had a little help menu with each meaning right on the screen at the touch of a button, O2 wasn't ready (IM's) and found a dead clutch pedal switch, easy part swap and easy to see that the O2 was responding appropriately via live data graphs. I was able to read up on how to set it and with a little driving from the manual it set everything and the switch replacement worked as well. Now the car is all ready to go in. The interface is super easy and it picked up a few other things reported that didn't show on a cheep-o scanner. I was able to get all readiness codes set and verified and all the other things fixed up with out wasting a trip. Its a little pricy for the feature set, but they seem to have done a good job with this one, so I'd say just for the easy of use / navigation, and stored lookups and help, this was a good grab and go tool. For a basic scanner it helped for my use case so if that's all you need this one made it way easier. Graphing data was a huge plus! Graphs are a little slow but perfectly good enough for a handheld tool (look its not a Textronics scope here). I was able to capture O2 stream data and changes reasonably quickly with a good sample rate, that I could verify it was in spec and wasn't having to guess. It graphs most PID's smoothly on the ODBII port. If you need some other feature sets you'll probably pay more, but this was worth it for just being easy to see, ready, and troubleshoot with out looking up anything in a tiny booklet or having to go in and google. Autel FTW!

The code scanner came in the mail (USPS) in two days. The user manual seems not to the point because all I wanted to do was to be able to hook up the tool and find out what caused the check engine and VSC lights to come on an '01 RX300 a day after I charged up its battery. I kind of muddled through and in the end just hit the clear all codes button figuring the reason was not life threatening since only the yellow exclamation mark lit up. I wish the manual would show a pictorial step by step on checking and clearing the check engine light including whether the car needs to be started or not. It will be nice if there is a Youtube video on using this scanner model but there was none. Also I couldn't find Lexus listed among the manufacturers so I chose Toyota and it came up with a code saying something about air-fuel mixture but really not a detailed explanation on what it is and how to act on it. The CD doesn't show anything new except to show the scanner model and code version. Mine says the code was burned in August this year. The updating tool was strange since it asked for files in your computer folder so I figured that meant one has to first download files from the Autel web site. I did click on the Update mode and the scanner page came up with "Program Mode" which seemed to be stuck as I couldn't go back to other pages until I unplugged the USB cable. Its also not clear what I/M stands for or what to do with a page of spreadsheet like display. So if you know how to work with this tool I'd appreciate a simple tutorial. Other than that I expect good things from this tool.

Exactly what I needed to read the codes from our '14 MB G550 and '15 Honda Fit. Tested and the tool communicated with both of these vehicles. Haven't had any issues, but made this purchase to diagnose my cousin's '10 Lexus RX350. It found the fault code and interpreted the fix. Replaced the O2 sensor, cleared the code and all is back to normal.This Autel 519 cost $65. The replacement part (Denso 234-4509 Oxygen Sensor) was $72. My cousin bought the part and split the cost of the Scan Tool. He saved $340 vs. going to the dealer (Lexus labor rate in our area is $125/hr.). They quoted him $450 for parts and labor. Took both of us about 3 hours to do this install plus clean the engine bay, change oil/filter, rotate tires, change the cabin filter, replace the front brake pads and bleed the brakes!!! Although my labor was FREE, we enjoyed the rest of the day chugging down a couple 6-packs of my favorite lite beer!!!!Seller shipped from TX. as indicated on the listing. Although Prime not mentioned, it arrived in two days!The AL519 is a few more dollars than Autel's other models, but they won't do the enhanced Mode6 which most new Euro cars now have. Am liking the color-screen and the "beep" function when buttons are depressed.. Gives that "professional" feel when performing diagnostics. Length of the supplied cable is more than enough to comfortably reach from any OBDII port to the driver's seat.As with most scanners, operation is similar: without turning over the engine, turn the key to "start" position (or push "start-button" to start mode w/out stepping on the brake) and the Autel starts communicating with the vehicle's CPU once the corresponding button is pressed from the menu!!!Described as "used-like new". Nevertheless, it came with the original box, instruction manual, storage bag and accompanying cables (2). IMO, this is a new item! The original screen protector still was on the unit. No marks anywhere. It's as if no one even touched it. I highly recommended YIT-BathroomOutlet as one of Amazon's trusted sellers.UPDATE: Installed LED DRL's for the 2015 Honda Fit and initially used the factory DRL fuse junction (#25). That made all the lights go on and shut down the instrument cluster. The Autel stored the codes and showed U0155 (Lost communication w/ instrument panel Cluster). Erased the code and re-scanned. No more codes and all the yellow warning lights are off. What a time-saver this tool is, plus, saved $'s from going to the dealer to have it diagnosed.UPDATE 2: Just diagnosed our nephew's 2002 MBenz C240 Wagon. It had a check engine light on. Cause faulty gas cap!!!!
