Best Car Diagnostic Tools and Scanners
Car diagnostics explained
Are you continually seeing error lights pop up on your cars dash? Orange or green lights indicating something is wrong with your engine, electrical system, ABS or airbags? A car diagnostic tool will show you exactly what is wrong and give you the power to fix it yourself and remove the error light and code.
With a car diagnostic scanner you can get peace of mind and the most important thing is, if you are getting work done on your car, it’s a great idea to run the diagnostic tool on your car to see what errors are showing up, if any. This way, when you send it in to the garage for an MOT or similar check up you can be sure that there aren’t any real errors.
The great thing about this is that you wont get ripped off by your local garage and if it’s not a real problem or something you can fix yourself, you can save even more money and sort it out without having to pay anyone else. Usually with just a check you can pay more than £20-£30 for a car diagnostic check. If you get one of the cheaper diagnostic tools you’ll be saving money as soon as your car is checked more than once by a garage.
These diagnostic tools are not cures for your cars problems, they merely let you know what is happening, sometimes you have an error that isn’t even a problem, this is where these devices shine. You can see what it is and clear the fault and remove the light on your dash.
Will The Diagnostic Tool Work For My Car
Works on most Standard OBD2/EOBD protocol cars, SUVs, mini-vans(12V) .European and Asian from 2000 year, US from 1996 year, Japanese from 2008 year.
As long as it has the OBD-II interface or on board diagnostic ii connector then you should be good, we have included below how to find this in your car. You can even use this link to check where the connector is on your car.

Make sure you double check your car has an OBD interface so that you can check the diagnostic tools work with your car. Another point is that OBDII is NOT for use on pre 2003 ford diesels they are OBD1 not OBD2.
Where is OBD-II/OBD2 port?
The most common place to find the OBD2 port is under the dashboard on the driver’s side beneath the steering wheel column. Most vehicles have the connector under the dashboard on the driver’s side, but some can be found near the center console area or even on the passenger’s side of the car.
What Other Things Can You Use A Diagnostic Tool For
As well as checking your current car, you could even use this scanner on a new car you would like to purchase to check everything out and make sure there are no real problems.
What Do All These Car Fault Acronyms Mean?
- OBDII
- EOBD
- OBDI
- DTC: Diagnostic Trouble Codes
- I/M: Inspection and Maintenence
- ECU: Electronic Control Unit
- PID: Proportional-Integral-Derivative
OBD-II is an onboard computer that monitors emissions, mileage, speed, and other data about your car. It’s connected to the Check Engine light, which illuminates when the computer detects a problem. The OBD-II onboard computer features a 16-pin port under the driver’s side dash.
Something We Thought We’d Need, Batteries
Do you need batteries for your devices? No, all of the car diagnostic devices run off of the cars power, you need to have your car powered to obviously see the error on your dash and this will also run the device you use to check errors and remove them.
If you want to read all the code faults your car, van or truck can muster, we’d recommend nothing but the Topdon, it can read ABS and SRS Airbag fault codes as well as any engine faults and show you emission graphs too, it does it all.
It costs a bit more than the others, but is a great piece of equipment. Just behind it comes the BlueDriver Bluetooth OBD2 Connector that you use with the Android or BlueDriver iOS Application that you download for your phone. An amazing little bit of kit, it doesn’t do everything the Topdon does but doesn’t come far behind it. That is helped by its relatively low price and that you can use your phone you already own to navigate the errors or see live engine information.
If you are working on your car quite a lot and want a dedicated OBD2 diagnostic tool and don’t want to use your phone and want to work out why that engine light is showing we would recommend both the Foxwell NT200 and OM123 Mate, also known as the Intey Phinx depending on where you buy it. They have a great simple interface, not too many buttons and will have your errors showing in a matter of seconds once plugged in.

Review of BlueDriver OBD2 Bluetooth Smart Phone App Diagnostic Tool
This is a review of both the BlueDriver OBD2 Bluetooth Device that you plug in to your car and the diagnostic tool application that you download to sync with this little device.
Wait, what? I can plug this little bluetooth device in to my OBD2 connector in my car and then view all of my cars diagnostics using an application? Yes, yes you can.
So here is the gist of it:
- CLEAR DASH LIGHTS – If your light pops up on your dash, you can sort it with this little device and your smart phone, magic!
- EASY INSTALL – If your car was made in the last 20 years it should be compatible, we have included an obd2 search above to see if your car has one
- EASY APP SETUP – Just download this application using your Android phone or iPhone or tablet
- SIMPLE TO CONNECT – Get the app, plug the adapter in to your OBD2 connector, put the code in to the app and you’ll be flying
- FREE 12 MONTH WARRANTY – You get a 1 year warranty on this, if you use it more than twice, you would easily have saved money compared to going to your local garage.
Thats basically it, it’s an amazing little piece of kit and if you already own a smart phone or tablet, which i’m guessing you will, just buy the adapter. You’ll get a great colour info read out compared to some of the other diagnostic tools.
It doesn’t clear all the codes like the Topdon Diagnostic Tool does but it does enough and shows you vital car information that you may also want to check out.
Do You Race Cars or Other Vehicles
You can see real time data on your smart phone and record it, unlike other diagnostic tools, which means that as you are doing a lap, you can record this data and look at it later. You get important stats on the screen such as your rpm , air fuel ratio , shift light etc.
Pros
- You only need to buy the bluetooth adapter and fit it to your obd2 connector
- It’s a lot cheaper than some of the other alternatives
- You can use your smart phone and tablet with it to read error codes and delete them, which means you can use tech you already own
Cons
- Doesn’t read or delete all error codes, only engine faults
- You have to download the application on your phone to use this and enable bluetooth, you get the free app with the purchase but there is also a pro version which you might to pay for
Verdict
It’s just a really simple to use gadget that does exactly what it promises. Really insightful information is shown on your phone and if you have any errors you can delete these as well! It’s a great little product and easier to use than most of the other car diagnostic tools because you just have to learn the user interface on your phone, rather than a whole brand new menu system built in to a separate diagnostic tool, like the others we have reviewed.

Review of Foxwell NT301 Car Diagnostic Tool & Code Scanner
This is a review of the Foxwell NT301 Car Engine Scanner and code reader tool.
We received this product, like the others, unboxed it and plugged it straight in to our OBDII connection in our Panda. We didn’t have any warning lights on our dash but we thought we’d see what we could check with this diagnostic device.
Here is what the product offers, we’ll go through each bit in our review below mentioning how it works.
The Foxwell NT301 is an advanced engine fault sensor it will not read faults from other parts of your car, if you have warning lights for ABS or airbags, this will not be able to see them nor remove the warnings. This is stated in the product description and we thought best to highlight this. We didn’t have an ABS or airbag warning so didn’t need to test for this.
What this is perfect for is checking how your engine is running, we have a little bit of crud in the top of our engine where we add new oil, this is due to the previous owner only doing short distances and we wanted to see if anything would come up and nothing has, which is great. We’ve since changed oil filter, oil and do nothing but big miles in our little car now.
In addition this model comes with a battery scanner that can read battery voltage, analyze battery healthy status, view charging status and detect faults and bad cells. It allows you to check battery condition of 12V 100-1100 CCA regular flooded, AGM flat plate, AGM spiral, as well as GEL batteries, and give you a test result display in about 3 seconds.
Car Compatibility for Foxwell NT301
Engine management diagnostics on ALL* 2001+ petrol and 2004+ diesel UK-sold cars
(* – Passenger cars sold from new within the EU, with fewer than 10 seats and a gross vehicle weight rating of less than 2500kg)
If you tick all of the above boxes, this device will work with you.
Overall, the Foxwell NT301 is a really nice looking diagnostic tool, even with all of its buttons it is simple to use but feels a bit plasticy and not thoroughly durable, who knows what would happen if you dropped it. Saying that, you will only be using it for a few minutes at a time and then putting back away and it will more than withstand this.
If you are after a device to check engine problems, check codes, car information and remove faults specifically for the engine, then this device will do just that.
After that, it gets a bit difficult to use, it has a lot more buttons than others and the menu system is quite intensive. It doesn’t help the instructions you get with the device don’t offer much more.
Pros
- Great looking device which will show you all your engine fault codes
- Can clear engine fault codes using this diagnostic tool
Cons
- Doesn’t show and cant cancel error codes for everything, only engine faults
- A lot of buttons which it may not need, some others are a lot simpler to use and do just as much
- Instructions are poor, don’t really instruct, only show you what you’re already looking at
Verdict
A nice little device for any engine fault or check that you may want to do, you have quite a few options regards emission checks and car info but it doesn’t do everything and costs a bit more than others.
