I purchased this OBD2 Diagnostic Scanner device (BlueDriver OBD2 Scan Tool for iPhone and Android) a couple of weeks ago after the Check Engine light came on in my car. Plugged it in and, using BlueDriver’s iPhone companion app (also available for Android on the Google Play store) discovered immediately that the CVVT solenoid was reporting problems, code P1332.
I was able to knowledgeably speak with my mechanic rather than just dropping it off and waiting for the bad news. He confirmed the solenoid was gummed up as a result of my not having had an oil change in over two years (I’m terrible, I know) and $45 later I was on my way.
Live Scan OBD2 Diagnostic Scanner
But my favorite feature so far is its live scanning. You can plug it into your OBD2 diagnostic scanner port and leave it there. It’s only operational when you’re driving, so there is no reason to have to remove it. Then, every day on your commute you can start up the app on your phone and track the data reported by every component of your car in real-time. You can then save the date to a .CSV and email it to yourself.
It would be great if there was a companion app for the desktop, allowing you to sync your reports and compare day-to-day. But importing the file to Excel, if you’re good with Excel, can be much more powerful than a dedicated desktop app.
Following the oil change, all of my metrics improved. So not only was I able to discuss the issues reported by the engine with my mechanic, I was also able to compare the before and after data collected using the BlueDriver device.
There are a lot of these devices to compare on Amazon, but this one is the best reviewed and I’ve found it to be the top recommended item in several online reviews in automotive blogs and publications.
