Hardware & Design

1. Bluetooth connection for remote diagnostics

This scanner provides wireless convenience. All you need to do is plug in the Bluetooth dongle to your car’s OBD2  port.

Then you can freely move in, out, and around your car while running your tests.

Based on my tests, the Bluetooth connection works best when you’re within 30ft from the dongle.

As long as I remained within this range, there was no lag between the scanner and the dongle.

Some warning: 

It’s very easy to forget the Bluetooth dongle in the vehicle after completing a diagnostic session.

This is something to watch out for, especially if you’re a mechanic — you don’t want to forget your dongle in a customer’s car.

2. Sturdy design for lasting use

The NT809BT looks and feels well-made. It comes in a sturdy plastic carrying case.

It also has a rubberized side.

Consequently, it’s unlikely that it’ll slip out of your hands and you’ll lose your screen.

3. Sensitive Touchscreen that makes navigation easy

The NT809BT has a 7-inch touchscreen, which is pretty large. The screen is precise and sensitive — you can scroll through the menu even when wearing gloves.

The display is also easy to read, even in daylight, so you won’t have to squint your eyes when using your scanner out under the sun. 

4. Adjustable Stand

The NT809BT tablet is a handheld device.

However, it features an adjustable stand that enables you to work with the scanner without holding the tablet in your hands.

You can also use this stand to hang the scanner on your steering wheel.

1. Save you tons of money by finding your car’s problems at home

This NT809BT has a wide range of vehicle needs with functions ranging from basic to advanced compatibility. 

If you’re a full-time mechanic, you can serve a wide range of clients with this tool. 

And if you are a DIY enthusiast, the NT809BT can help you run system diagnosis on your vehicles and save the money you’d have paid a mechanic

Using the NT809BT, I did:

  • run an ABS diagnosis in less than a minute.
  • clear the airbag codes on an MK6 GTI in less than 2 minutes.
  • detect the faulty impact sensor on a 07 GMC Sierra.
  • reset the airbag light on the 2004 Honda Pilot.
  • etc.

2. An powerful reset tool, but doesn’t support the key programming function

The NT809BT includes 30 commonly-used reset functions, including:

  • EPB reset, 
  • ABS bleeding, 
  • Oil reset, 
  • SAS calibration, 
  • Injector coding, 
  • Tire size change,
  • more

Specifically, I tested the EPB reset while doing a rear brakes job on an Audi Q3, and it worked flawlessly.

It’s also convenient to use the NT809BT for resetting the service indicator. 

Unfortunately, this scan tool doesn’t support key programming.

If you’re looking for a pro scanner for programming new key fobs, buy another one.

3. Affordable bi-directional scanner

The NT809BT is a full bidirectional scanner, as it supports active tests for both ECM and doors. 

For the number of functions it supports, this scanner is a fantastic bargain for a bi-directional scanner under $600.

Some of the active tests I usually perform including:

  • locking/unlocking doors
  • rolling windows up/down
  • turning the lights, cooling fan, and fuel pump
  • turning the horn on/off
  • etc.

Price, Warranty & Update Fee

At under $600, the Foxwell NT809BT is one of the costliest bi-directional scanners you can find on the market. 

You get a one-year manufacturer’s warranty and free software updates for the first 3 years following your initial registration.

Afterward, software updates cost $160 for one year, $280 for two years, and $400 for three years. 

These updates aren’t mandatory, mind you. If you choose not to update your software, your scanner continues to run on the previously installed software.

As you’ll soon see, buying this tool might be worth it if you’re a professional mechanic or an advanced DIYer who’s often working on different cars. 

But if you’re a beginner, you’re better off choosing a less expensive (and sophisticated) tool.

Key Takeaway

The Foxwell NT809BT is a professional OBD2 scanner that can offer all the active tests you need. 

Wireless connection sets NT809BT apart from other bi-directional scanners at this price point.

Most mechanics and advanced DIYers will consider it a good bargain
