Foxwell NT520 BMW feedback:
1. Very helpfull tool fo diagnose car and prevent sirius damage

2. It did exactly what I needed it to and then some! I had the original index 1 injectors in the car I bought (n54) and upgraded to index 12 it coded them without any issues. Little side note it’s designed for not only Bmw and minis but I was also able to read codes on my Mercedes. Just an overall great product exceeded my expectations! So if you plan on doing your own maintenance this is a must have in your tool box.

3. Great tool for DIY guys like me… One of the best scan tools I’ve used so far..

4. Needed something that could do more than the average Bluetooth OBD scanner. Owning a BMW it’s awesome to have dealer level diagnostic. This way I know what they would see and I can fix it accordingly without paying crazy dealer prices

5. This has been worth its weight in hold for me doing various work and modifications on my MINI. It has allowed me to do the brake line test after installing braided lines, see faults I didn’t know I had that do not come up as check engine lights. If you own a MINI, BMW or fo uou own work on a Rolls Royce, buy this tool.

6. Foxwell NT520 scan tool is fantastic if you own a Mini. I have been using it for a few weeks, and it has already easily paid for itself with money saved. I’ve been able read any code, and also register a new battery ($125 saved right there) it is great. Wish I had picked one up sooner!

Foxwell NT520 Porsche feedback
1. First use: I purchased this tool primarily to reset oil service light on our ’15 Cayenne Diesel. After first updating the software to the latest version it worked great. Looking forward to testing all th features and also trying it on our ’02 996.

2. Powerful code reader: This code reader is perfect for the home mechanic. I own two Porsches so I bought the Porsche specifics version. You can also buy other vehicle modules online for about $60. I also own a couple of Chevy’s so I will probably get that module too. Ready to use and detailed information. Seems to have good online support.

For more will be updated…


Hope it helps.
