Best OBD 2 dongle

[surpip]

I had the "service DEF system see dealer" message show up yesterday. I took the batt cables off and shorted them to reset the computer, and that seemed to do the trick, lights off now, but I figure I need to get something to read and clear codes now that is out of warranty. 2016 3500.
I have an I phone, but GF has a droid so I can use either system.

My obdlink MX+ works pretty solidly. Have had no problems with it. Use Alfaobd with it also to set TPMS and play with a few other settings.

I have the Bluedriver dongle. Some limited data logging and realtime sensor data along with the normal scan and clear functions. Definitely a step below a professional scanner that lets you test relays and circuits but it works for my needs.

I had a cheaper unit before that was a pain to connect, the bluedriver came with more slick packaging and marketing wank but it actually seems to work better too.

Probably the def heater went out. You can just ohm the wires to check it

I also have the BlueDriver, I got it for free and it’s ok. Pulls codes and has some data
