2PCS ELM327 OBDⅡ Car Auto Diagnostic Scanner, Professional Automotive Bluetooth Scan Tool and Code Reader, Universal Vehicle Interface Adapter Diagnostic Tool Scanner

It works Great !!

I had been using the Torque app with another dongle and got two of these to keep in my cars, to have just in case.Plugged it in and paired it to my phone and fired up Torque. And that's when it all went bad. I have a Chevy Traverse. Started to the car to do live monitoring... Engine light came on, traction control shut off & threw message on driver info center. Car went into limp mode. Restarted and car would no longer move at all!!! I was stranded. I guess I should have tested at home but never had an issue like this before.I had to get a ride and get another scan tool to clear the codes. Tons of communication errors, trans requested mil etc.Still have a permanent U0100 for the loss of communication. But after resetting the codes I was able to drive. Still don't know how much damage was done to ECM/ other modules. I pray I didn't ruin my car by using this module. A huge mistake buy something else.

As long as you follow the instructions, & have your phone & computer synced, this little 5$ peice of plastic will give information that only a good car guy can understand. Pay the extra 5$ for life then you can scan multiple cars, & get more information only the good car guy can understand. It's better than going to the dealer just to hear Goober tell you that you need'Blinker Fluid'. Know what's wrong ahead of time !

I'm still trying out this item

This thing may work well on Android but I couldn’t get it to work on iOS. I am giving a 1 star because of the sneaky scammish way they hide the fact it doesn’t work on iOS. It’s buried on one of the picture slides towards the end at the bottom with little contrast. (So it is hard to see) even ai multiple systems say do to protect description it looks as though it should work.

Both worked and are good for reading and clearing codes, but if left connected it will introduce communication error codes and crash the entire bus. It's not perminate. Just clear the codes and the vehicle is good again.

One does not work the 2nd one does. Buyer beware knowing you can receive one that does not work. One works as it should.

Just an add on to the dudu7 head unit best stuff ever
