Autel AL519 Reviews:


I am very pleased with this Autel AL519scanner. Works exactly as you would expect. I did read the manual which contains a wealth of background information on the ODBII system as well as the use of this device. The LCD color display is fantastic (bright, easy to read, nice resolution). The device feels solid in your hand (does not feel cheap) and I like the rubber bumper which protects the unit from accidental drops.

I feel this is a great value as compared to what you can find from Harbor Freight or Home Depot. Great value for the features this device contains. I am recommending this device for anyone in the market for a low cost OBD Scan Tool.


Excellent product and simple to use for domestic, Japanese and German cars. Have been using this reader for over 150 cars personally and not in shop setting.


This product is one of the best auto scan tools that I have ever used and well worth the price.
My check engine light was illuminated on my pickup and the Autel Tool read the codes and provided information as to what was wrong. The dealership read the same codes and confirmed that the problems were exactly what the Autel AL519 had indicated. After I repaired my truck, my daughter drove it down the road as I ran a complete analyses on my truck’s performance. I could not believe all the information the tool provided. Buy It!
