AutelAutoLink AL329(Upgraded Ver. of AL319/MS309) Code Reader with AutoVin, One-Click I/M Readiness Smog Check, OBDII Scan with Live Data, DTC Lookup, Engine Fault OBD2 Diagnostic Tool

This is an excellent tool for determining your "check engine" light issue before heading to your friendly car repair shop. However, I think it's important to address some of the issues I had upon first-time use.(1) The "directions" (I am being polite) are quite small and the images virtually useless. They stress the need to first download the free Maxi software, which must be installed on a computer before first use. That software (PC and Mac) is available on the Autel site. The software is easily downloaded, but cannot be used with the unit unless you have registered on the Autel site. Nothing indicates that registration is required to use the software. I found out through trial and error.(2) Once downloaded and installed (and after registration), one opens the application and plugs the unit into the computer with the provided USB cable. The unit then notifies about firmware updates, which are easily applied, but nerve-wracking. (As a systems administrator, I wondered while it updated: "What happens if the firmware update bricks the unit?" But all went without a problem.)(3) I attempted to download the user manual for the unit, but found a 404 error (page not found). That needs fixing pronto. Actually, I didn't need it.(4) Once finished with the update, the unit is ready for use. I spent more time attempting to locate the diagnostics port on my vehicle than I did getting the unit operational.(5) I am concerned that most buyers who are not savvy with computers or the Internet might find all this a bit overwhelming to do. The instructions in the box need to be seriously updated. I doubt the stockholders would agree.(6) My unit came with a free 30 day access to some guru site for expert advice; but, alas, that coupon expired two years ago.The unit works flawlessly and is fairly intuitive. I was going to give it four stars for the company's lackluster Internet portal, but decided Autel is not in the business of thinking like a system administrator. So, there's that.

Love the reader only thing I would fix is when doing a drive cycle to clear monitors it beeps have found a way to turn that off. This is great value fir the money.

Works exactly as described.

I’ve had my fair share of OBD2 scanners but this is my favorite out of the bunch also carry it around my shop van so when u do long distance runs, I make sure everything is running smooth! But for overall usage I recommend

Great Product!

Works on a 2011 Subaru, 2020 ford f-150 it does not recognize the transmission module. Overall pretty good for the money.

I like this model because I do most of my own auto repairs. This gives me a read on what problem to look for, whether it's something with the engine or the brakes. Easy to use and so far dependable.

Good buy
