 Foxwell NT644 Pro review:

The diagnosis offered by Foxwell NT644 Pro is typically accurate. Furthermore, I had an easy time using it. I mean the tool is not complicated to use. I think any car owner can use it. But you are supposed to understand the readings and know how to interpret them. Nevertheless, it does have some shortcomings that I will mention in the article.


  • NT644 Pro VS NT624 Pro VS NT414

Compared with NT624 Pro and NT414, All these scan tools will perfectly work on most car models. However, the Foxwell NT644 Pro has an upper hand compared to the three.

It is the only model, among the three, which can deliver car battery configuration and Diesel Particulate Filter functions.

  • Foxwell NT644 Pro Highlights and Functionalities
  1. Plug-and-Play

One thing that I liked about Foxwell NT644 Pro scan tool is that it is a Plug-and-Play type of tool. As long as I plug it into the OBD port in my car, it will display the features accordingly.

The features and functions are also well-arranged for easy accessibility.

When I click on the Enter button, it will automatically connect to your engine. The buttons are also quite responsive.

2. NT644 Pro Diagnostic Functions

What I am impressed is that it can reset the oil light, as well as read and clear error codes from most systems on the vehicle.

I used it to diagnose the Engine Control Unit, traction control, transmission, entertainment, Tire Pressure Monitoring System, navigation, and the stability control systems.

Moreover, I can view live data with NT644 Pro. The Diesel Particulate Filter and battery configuration features are other unique features that are in this tool.

The tool offers live graphing too, which I think can be useful for mechanics.

The tool automatically retrieves the VPN when you want to connect it to the internet. Though you can also enter the VPN manually.


What it can’t do: it doesn’t clear airbag codes. Actually, it didn’t even list the airbag codes..


  • Foxwell NT644 advantages & disadvantages:


. The live data feature allows you to view most data, even the wheel speeds.

. The keypad on the tool is easy accessible {and well-arranged} for easy usage.

. It runs fast as soon as you plug it to your car.

. The rugged sides guarantee that it won’t slip off your hands as you use it

. The Foxwell NT644 Pro can do graphs too

. You can connect it to the internet to upgrade the vehicles, parameters, and bug fixes.



.It may not work with some vehicles, like Volvo

.The scan tool failed to read/list airbag codes

. Cannot update the software directly with the USB cable


  • Target user:

Honestly, anyone can use the Foxwell NT644 Pro. No matter who you are a car owner that wants to know the detailed condition of your vehicle, or you are a mechanic with further experience, the tool will serve you well. Its ease-of-use makes it a good DIY tool.


On the other hand, the extra functionalities make it a good choice for mechanics.

  • Foxwell NT644 Pro test reports:

Have an Autel MS906TS. I find scan tools interesting, and I love to own and use them. The Chinese brands give so much value for money (Autel, Launch, Foxwell). Among Chinese made scanners, I know least about Foxwell. But so far yours seems like the best compact scanner out there for a DIY. And even live data graphing, wow. I’m really curious about the GT80 Mini more than the Plus version. That’s their newest scanner with Win10Pro. The Plus has Win8.1Pro and I don’t think it’s wireless like the Mini. And last I wanna say, dont buy Launch Diagun IV, I did as it is a compact Android based scanner. The newest model from Launch. But it is more expensive and with a lot less live data functions that the Foxwell NT644 Pro.

-I bought an nt644 last week and I am really happy with it. I bought it as its able to register new batteries as needed in newer bmws etc and also the park brake reset as more and more cars have them

Live data in the Foxwell NT644 Pro scan tools are great. Every bit of information are sometimes greatly useful.

It is actually a great tool, I’m a user of this tool from past couple of months.

– it has TPS settings

The difference between TPS settings and throlle body adjustment or alignment: when you replace to send to you have to calibrate it the Foxwell will allow you to calibrate it so the car knows where it is and what it is doing

– has throttle relearn on some cars, worked a threat on the misses mk4 golf.

– Can do SRS reading

– Been very impressed with every Foxwell tool I’ve used, for the money and for what it can do no complaints my end.

– it does do graphs.
