Foxwell NT650 reviews: Pros and Cons

Thanks to all users of Foxwell NT650, who share their reviews on what are Foxwell NT650 pros and cons. Generally speaking, Foxwell NT650 is not good at reading and clearing codes (Foxwell NT624 can do); but if you need the extra special functions, it might be worth it.


  1. I own a 2015 Passat TDI SEL Premium. I started getting the ABS/ESC/Airbag/TPMS lights on a drive to work one morning. At first, the lights would come on the go off for a brief second, then right back on. Eventually the lights became to sporadic to track but at least one was always on (this also knocks out your cruise control). I purchased the Foxwell NT650 with high hopes and the unit did not disappoint. I was able to clean all bogus codes (erroneous voltage readings, false positives, etc.) and focus in on the ones that mattered. The unit narrowed the problem right down to the left rear ABS/speed control sensor. After a quick trip to the local auto parts store, ($54USD for part) and a simple replacement, the car was back to working perfectly. The NT650 is extremely user friendly, powerful, and quick. I look forward to using the unit many times in the future!
  2. The screen is easy to read, the buttons are somewhat stiff but still work ok. The included data cable is ridiculously thick and stiff, and could have easily been made thinner, but it is still functional.

Data is stored on an SD card inside the device.

Updates are done by inserting the SD card into your computer and running the updater software that you download from the Foxwell site. It comes with a USB SD card adapter so you don’t need an SD slot in your computer.

Foxwell NT650 reviews: Pros and Cons


  1. Foxwell NT650 checks LOTS of parameters, and the real-time data and graphing are very helpful. The long connector cable allows me to drive while a passenger checks real-time data from the passenger seat. The front panel controls are pretty straight-forward as well. I wish I could get more functionality for the vehicles I currently own, and less for a Bentley, Mercedes or BMW. If I could afford one of them, I could probably afford to let the dealer do my diagnostic work for me.

Foxwell NT650 reviews: Pros and Cons

  1. Foxwell NT650 helped me diagnose check engine light that would come on. hooked up the meter and found a misfire on cylinder three, found a bad coil that had been slowly dying.
  2. I have tested many makes and models from 1998-2015. Vw, Hyundai, Ford, Nissan and it performs well for each application. Update was easy and fast as long as you read and follow the instructions. For a scanner under $300 this has to be top on the list. I previously owned an Autel OBD2 basic engine reader, if you are ready for the next step up then buy this scanner. I was originally thinking of spending $1,300 for a full system and am now realizing you don’t need it to do most of the work. The live data on this device is sufficient to diagnose problems. The Foxwell reads all the major systems you need.


Pros and cons

If you just need to read and clear codes, this is not the device you want – just get a cheap ODB reader like Foxwell NT624

But if you need the extra functions, it might be worth it since dealers can charge a fairly high cost for simple things like replacing a TPMS sensor.

Doing a firmware update is easy, be aware that this works best on Windows 10. Mac is not supported.
