For your information:

You ordered one Foxwell NT510 /NT520 BMW, Emillia may ship you a Foxwell NT530 instead, considering Foxwell NT530 can work with BMW F series that nt520 can't. nt530,nt520, nt510 are all made by foxwell, and NT530 is the best. So it's not necessary to worry that seller is trying to ship one knockoff product instead.




Where to buy Foxwell NT530, NT520, NT510 scan tool?

foxwellshop | 23 August, 2019 05:33

This article organizes the stores that foxwell NT530/ NT520/ NT510 customers often visit, as well as their reasons and experience.


Car models and years:

Two 2011 328i X-drive

One 2000 F350

One 2000 Toyota


Symptom: car went from a leaky VCG to not starting


Intentional seller:






Vote ebay seller:

Reason: cheap

NT520 with BMW software preloaded is about $150 shipped. Each additional manufacturer software is $60.

Search Foxwell on ebay and you will have answer.


Vote Schwaben:

There is no reason to like it.

Schwabben version of the NT510/NT520 costs more, for BMW diagnosing software, It the exact same thing with same BMW software preloaded.


Vote foxwelltool.com:

Reason: Works fine.

Feedback: bought an nt520 from foxwelltool.com...everything worked fine...

NT520 will register batteries but it will not code batteries. Most BMW scanners will register batteries but not code the battery. To code the battery you need BMW INPA or ISTA, both of which are 100% FREE.


Vote Foxwell NT530/ NT520 or Autel MaxiCheck MX808:

  1. Autel MaxiCheck MX808 is suitable for those who have more than 5 cars in a family. Its price ranges from $306 to $459 and not suitable for DIYers.


  1. If you have less cars i.e Two 2011 328i X-drive, one 2000 F350 and 2000 Toyota, buy one Foxwell NT530 with BMW software and pay $60 for Toyota would be more cheaper.

  1. Throttle Body Alignment (TPS/TBA)

It's very common to see a customer pull into the shop with a Volkswagen or Audi that just will not idle correctly. One of the possible causes is that the throttle position is not known. When the motion range is not known, the ECU simply has no idea where to set the throttle. The ECU must know the full range of motion of the throttle in order for it to properly control the engine. Using the throttle position sensors in the throttle body, the ECU learns the full open and full closed positions through various states (idle, part throttle, WOT) known as a Throttle Body Alignment (TBA).

  1. Gear Learning

The crankshaft position sensor learns crankshaft tooth machining tolerance and save to the computer to more accurately diagnose engine misfires. If tooth learning is not performed for a car equipped with Delphi engine, the MIL turns on after the engine is started. The diagnostic device detects the DTC P1336 'tooth not learned'. In this case, you must the diagnostic device to perform tooth learning for the car. After tooth learning is successful, the MIL turns off.

After the engine ECU, crankshaft position sensor, or crankshaft flywheel is replaced, or the DTC 'tooth not learned' is present, tooth learning must be performed.

Foxwell NT650 Feedback: cars, symptoms, test reports

foxwellshop | 28 June, 2019 04:22

Foxwell NT650 Feedback are put together in this post, in the form of cars, symptoms, test reports and using experience etc.


  1. Car model: 2005 Honda Pilot

symptom: always gives me a error light once a while

Foxwell NT650 YES:

Can easily change the oil at home, to reset the oiling sensor.

To diagnostic my error code and I can order parts online to fixed it.


  1. Car model: many makes and models from 1998-2015. Vw, Hyundai, Ford, Nissan

Foxwell NT650 YES

Update was easy and fast as long as you read and follow the instructions.

The live data on this device is sufficient to diagnose problems. The Foxwell reads all the major systems you need.


  1. Foxwell NT650: Easy to use

you need to plug it in to a car/computer for it to actually turn on) it does a lot of functions for the costs and its light weight and comes in a hard case to keep it protected in a garage/car...


  1. Car model: Bentley, Mercedes or BMW

Foxwell NT650 YES

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.


  1. Reset check engine light on

symptom: Check engine light on

Foxwell NT650 YES

Hooked up the meter and found a misfire on cylinder three, found a bad coil that had been slowly dying.


  1. Car model: Honda, Nissan, Ford, Perodua, Vauxhall, Dacia etc

Foxwell NT650 YES:

- reset TPMS (tire pressure sensor). If you have a bad sensor on your wheel, you can install a new one and link it to your car. Without a tool like this, you'll have to go a dealer and have them link the new sensor.
- reset TPS (throttle body alignment). If you've ever cleaned the throttle body, you know that it has to be reset. Many cars require a special tool, and this will do it. I recently used it on a 2007 Honda Odyssey.
- do Mode 6 testing
- run ABS (brake) tests and procedures



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.

Car models: 2015 Passat TDI SEL Premium

symptom: getting the ABS/ESC/Airbag/TPMS lights on a drive to work

Foxwell NT650 YES:

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.


That's all.




Foxwell NT650 is not a OBD2 diagnostic tool

Looking for diagnostic and service tool, go for Foxwell NT520 scanner.




2012 Benz E550 weird issue (misfires): Foxwell NT520 helps

foxwellshop | 13 June, 2019 04:21

Car model and year: 2012 Benz E550 with 70k miles



car starts to stumble

Check engine light comes on. Check engine light flashes at idle, but goes solid while driving and seems normal minus the light under light load.


Trouble code:

misfire codes cyl 5,6,7,8 but nothing else. Clear codes.

Drive car around trying to repeat issue but Cars running flawless. Wtf? 3 days goes by, no issues, non cel. Driving home today, boom. Light comes on again.


Benz scanner to use:

foxwell NT520 scanner



Don't start changing parts until you verify source of misfiring, may not necessarily be coils or even ignition.
First, check all cam phases/sensor connectors for oil.


The codes are telling you it's a series of misfires so my first suspect is a connector or wire that may cause intermittent voltage drop to a component or components. Fuel issues can also cause misfires so at this point don't rule out anything. Agree that you don't get 4 coils going out at the same time or 4 bad plugs. However there may be an intermittent drop of source or trigger voltage to the coils. But again, a series or random misfires can initially point to several things.

So next questions:
- does your scanner capture freeze frame data ? It's data the pcm captures at the time any codes are set.
- can you also see real time run data at idle and approx 2500 rpm?
- do you have any wiring diagrams?

Scan data is needed to see what other components are reporting to the pcm. Can provide valuable clues as to source issue.


Action and question:

Ok started with the phaser plugs. One plug had oil inside and on the plug itself. Other one had a little oil inside. Question. There is a similar style plug just on top of those that had quite a bit of oil on it. Not sure what it is or if that’s normal. I’ll clean plugs and see what happens before i move on.



You will see that there are essentially 2 plugs for each cam, one for the cam phaser (adjuster) and one for the cam sensor. So 4 plugs per bank, 8 plugs total for the engine pertaining to the cams. All of these need to be clean, if there is oil, the leaking component (sensor and/or phaser) needs to be replaced. Oil is not supposed to be in there and can wick into the harness, often resulting in misfires. Hopefully the oil has not penetrated into the harness too far, but you absolutely need to clean it as good as you can. Meaning very clean! Emphasizing this a lot, but oil in that harness can damage O2 sensors, pcm, all kinds of things. Worst case means a harness and/or component $$$$ replacement, so immediate attention is needed if you are finding oil. You can verify extent of oil by opening up the harness at a further point if accessible to see how far it's gotten.

Arrie, yes I had mentioned fuel delivery issue as a possibility, but I'm thinking for now that the oil may possibly be the cause of the misfiring. Just have to see, but without any freeze frame or run data it's really hard to tell anything else about where to look and internet diagnosis aren't very accurate.
There's a fuel rail for each bank, feeding the injectors for that bank, connected to a single line that usually has a fuel pressure regulator on it. Scantool (one that can do obd modes 1-10) can see the fuel pressure to verify, or most rails have a schraeder type valve that you can connect a pressure gauge to. That doesn't tell the story about injector pulse, but that's ok, that doesn't seem to be an issue since it's random misfiring. Again, it's not really feasible that several coils or injectors have suddenly gone bad.



Pics can help to better understand what I'm looking at, you can see both phasers unplugged and then this plug is just on top of valve cover:




Yes those are the cam phaser/sensor connectors. Not good at all to have any oil inside of them. They are fairly straightforward to replace and I believe places like Pelicanparts, FCPEuro, etc. sell them as kits.


What to do next and problem to meet:

I pulled all 4. 3 have oil on them. Last oil change i used an extractor and sucked it out until it was dry (or so I thought). Added the correct amount and didn’t think about it. Drove around for a couple days and though I better check the oil. It was over filled by a quart (reasons i don’t love the extractor) and drained it out until it was good. Didn’t think much of anything but now seeing this I didn’t come away unscathed. I’ll toss in 4 new ones and chalk it up to a lesson learned. Glad I caught if after just a couple days.


My Left bank map sensor was reading .01 voltage. Right side was 4.19. Figured it was an easy fix. Not so fast lol swapped sensors side to side and voltage still read .01 on left so both sensors are good. Getting 5v on both plugs and ground is .03. I’m guessing it’s the signal wire giving me fits. I’m not sure how to diagnose it from here though.



You did the smart thing by simply swapping sensors to verify operation.
Just to ensure we are talking about the same thing, are these 4 wire connectors?
You really need a wiring diagram for your vehicle/engine to be able to trace wiring and connectors from the sensor back to the assigned ECU terminal.

I've got the diagram for my V6, so I'm not sure if any of this applies, but the process may help:
On left bank sensor (identified as Hot Film MAF sensors on the WIS diagram):
Term 1 Rd/Gn wire, I believe this is + feed (but I don't see battery voltage identified), goes to term 16 of ECU
Term 2 Bl/Bn wire, shows as ground, goes to term 18 of ECU
Term 3 Bl/Ye wire, shows as 5v ref to sensor, goes to term 68 of ECU
Term 4 Bl/Gn wire, shows as ref signal from sensor, goes to term 70 of ECU

If I was looking at this, I would use a backprobe at the pins at the ECU to verify continuity and voltage readings from each terminal of the sensor itself. Using a correct backprobe kit will help ensure the connector weathersleeves are not damaged. Not an expensive item.
I think you were seeing some residual voltage at the ground, check from connector to body bolt (ground) for continuity. This will verify that the wire all the way to the ECU (and thru the ECU) is properly grounded.
You saw 5v reference, need to ensure that the 5v reference remains with both engine off and engine running,
The return voltage is supposed to vary, depending on engine run factors. Check the corresponding ECU terminal to see if that same 1.8 voltage is present and if changes at all with engine running.
Since the sensors were swapped, it's a good assumption that they are ok. I would verify that Term 1 wire voltage. Check the right side sensor to see what the voltage reading may be, Term 1 on that one too. As you already had started to do, look at a known good sensor readings to compare.

Again, this is the diagram for my car and may (probably is) incorrect for yours, but the idea is to verify that all voltage/grounds present at the ECU terminals are continuous all the way to the actual sensor.
There may be a possibility that the cam sensor oil leak may have done some damage to the wiring but lets hope that it might be a corroded or poor connection somewhere.



My car has 3 wire map sensors. I’m Hoping the oil wicking isn’t the issue and wouldn’t know where to begin on that. If i can get a diagram i can find what pin it is i could atleast eliminate that.



Getting a WIS/EPC is less than $20 and would be useful to you.


You can also simply trace the wiring color back to the ecu. If you think it's the right wire first do a simple continuity check, ecu to sensor connector. If correct wire you can then check voltage. 3 wire is pretty straightforward, should be ref volts, signal return and ground, as you found. Do this for both sides so you can compare, should be the same or very very close.
I like using my scope for that, as the voltage waveform is easily seen and compared, plus it can be reviewed in milliseconds as the sensor works. However I think a digital voltmeter should at least be able to capture voltage window for comparison.



Picked up a foxwell NT520 scanner. Did some live data and watched the front o2 sensors. Both were right around 1.0/1.2 when all of a sudden the left bank jumped really lean like 1.28/1.3. Just after that started the car started to misfire. Looks like it’s my o2 sensor after all.

Foxwell NT520 scanner reviews for Mercedes VW Renault

foxwellshop | 24 April, 2019 05:55

Foxwell NT520 scanner reviews for Mercedes VW Renault: price, delivery etc.



I live in Romania Europe and I am interested in buying NT520 for my 3 cars:
- Mercedes G400 CDI 2001
- Vw Touareg R5 2003
- Renault Megane Cabrio 1.9 diesel 2004

Can you please tell me if I can buy the NT520 and if it will work with all these 3 cars, and where can I buy it from that will ship to Romania?
I can pay with PayPal.

Thank you,


Sales FoxwellTool.com reply:

The Foxwell NT520 comes with one car diagnostic software for free, and the other two for charging 60USD per one, that is one unit 179USD plus 2 software(60USD each) 179 + 60+60 , 299USD in total including  shipping cost to Romania by DHL or YANWEN. You can choose one of them. DHL will be quicker, 3-5 working days, but you need to pay for the tax your own.

YANWEN no tax, needs 7-10 working days to arrive, no tax.


If you agreed, we can send you a PayPal invoice, and you can pay it directly.



Yanwen seems better then.

And agreed with the price, so you can send the PayPal invoice.


Finally, this user got Foxwell NT520 scanner happily.

Definition of Foxwell NT520Pro Secondary air system Monitoring (INC)

foxwellshop | 05 April, 2019 06:43

I need help with your abbreviations on the screen of my new Foxwell NT520 Pro.


I am working on an I/M readiness problem in OBD2.


The screen shows “NC” for the Secondary Air. What does this mean please? Not Connected? No connection? Or what ? I tried a google search but only got North Carolina.:-)


The Durametric I usually use shows “Pass” or ”Fail” for these results. Very unambiguous.


Thank you,


Here is the “NC” for which I asked for a definition.


It appears in the I/M Readiness screen .The section is Secondary Air.


I checked the manual online and could find no information on this issue.


So what does NC mean please?




the NC is actually the INC. It refers to INC (Incomplete) - vehicle was not driven enough to complete the monitor.


It means, the vehicle does not meet the emission requirements and needs to be inspected for maintenance.
