Review: Excellent OBD2 Engine Scanner - I bought this scanner to trace and repair a fault on my son's car that had a permanently lit engine management light. I've never used one before so I can't compare it with any others. The Scanner is good quality and comes with all the leads that you need and is easy to use. The fact that I was able to diagnose and repair the fault, and I was able to turn off the management light means that with one use the scanner it has paid for itself. Well worth the money. I needed to contact nexpeak regarding installing the drivers. Support was excellent. The driver that wouldn't install was for windows XP so not needed. Things that I think could be improved. The instructions are written by someone who's first language isn't English and can be difficult to follow, but any DIYer will quickly get the hang of it. The instructions should have a glossary of terms at the begining, for example DTC-diagnostic trouble codes, DLC,MIL,I/M etc. I kept having to search to see what they meant. It would be better if you didn't need to make a note of the fault codes and go back into a different screen to see the definition. Overall I'm very pleased I bought the scanner. Very highly recommended. Review: Great piece of kit - This is my first Scanner/Code Reader and very impressed. I did lots of searching before buying and in this price bracket, seemed to get very good reviews overall. Sturdy, good sized screen, colour screen, long connecting lead (important), lots of functions and crisp buttons. Easy to use but written instructions could perhaps be a little better. Although once you've got the hang of it, it is really easy to use Works straight out of the box. Has lots of other functions which I am yet to explore This has saved me hundreds of pounds rather than going to a garage to get them to check any fault codes. I rate myself as a good car diy'er. Scan the codes with this reader. Go online to car forums or youtube and find the most likely things which would cause the error code and nine out of ten times you can fix it yourself for very little money. At worst, you'll know what the problem is when you talk to your garage mechanic. Really good and pretty essential for any modern car. ## Features - The diagnostic scanner obd2 code reader supports most OBDII protocols cars with 16 pin interface, including Kwp2000, ISO9141, J1850 vpw, J1850 pwm and can, car scanner diagnostic tool works on most 1996 US-based, 2003 eu-based and 2006 Asian cars, and newer OBD II/EOBD & can domestic or Import vehicles including passenger cars, suv, Light trucks etc. Note: NEXPEAK NX501 only supports 12V vehicles. - NX501 car diagnostic scanner is a great upgrade from the more basic diagnostic code Reader.

This OBD2 diagnostic scanner for mokka x 2018 engine b14net. **Q: Will this work on Maserati Gran Turismo** A: If this has an OBD2 socket it should read any engine faults and other codes but it is NOT A PROGRAMMER nor a subsitute for a dealer unit which will and would be able to tell you in detail where the faults are and what is required to fix them. With a car like this you would be better off going to a Guy who has a Snap-on scanner which would give you a much better idea in detail. I have a Saab 9-3 and it does well on that hhope that helps..good luck.. **Q: will this work on 1996 Mercedes 320SL** A: To be fair I’ve got a 62 plate AMG and this box of nothing is useless. It will tell you if your battery is charging and it will put the engine light out but that’s about it. If you need it for anything else but that then don’t bother as regards to an 1996 model it should tell you in the listing. 👎 **Q: Woud it work on fiat?** A: Yes. OBD2 standard range for reference: USA Car Makes should be after 1996; EU Based Car Makes after 2004; Asia Car Makes after 2007. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent OBD2 Engine Scanner *by J***N on 8 January 2019* I bought this scanner to trace and repair a fault on my son's car that had a permanently lit engine management light.

But went through the Youtube videos on how to update the firmware ( pretty easy even though a Bit Chinglish) , and now it does at communiate with the latest firmware. Back Again, So far tried this on : A Ford cmax/Focus , and all reading data Ok A Fiat Grande Punto Diesel all reading data Ok A MG ZR ( K series) all reading data Ok An MG ZT with a Ford 4.6 V8 ( right pig normally with even the proper gear ( but now it at least comunicates and reads a fair bit of data ) Still a bit limited with My ZT diesel ( BMW motor and Electrics ) but does read some data, but this a known problem for this car . Still got the 1.8 ZT turbo ( K series) to try with it weird ECU.. So all in all seems pretty good, bearing in mind how many cars/models are out there in the world , one cannot expect 100%. compatibilty . latest 2020 ...... latest update from the nexpeak upload tool and the 501 now does NOT read anything on MG ( bmw) cars , works ok on the Ford .......also the latest car a 330 D 2010 bmw, also will not communicate . so currently a BIG failure !!! so reduces the stars .. Revised 2.. back to 4 stars ....had very good support from nexpeak customer service... sent me file to "downgrade" or backwards flash the tool and at the moment does seems to be back to reading all our cars But still will NOT talk to the newest one 2010 Bmw 330d . ## Frequently Bought Together - NEXPEAK OBD2 Diagnostic Scanner, OBDII NX501 Vehicle Fault Code Reader, Auto Check Engine Light Scan Tool for Most OBD2 Protocol Car Since 2003 - Wynn's Diesel Particulate Filter Cleaner - Cleans & Regenerates Blocked DPF Soot Filters - Reduces Soot Formation & Emissions - Compatible with Diesel & Hybrid Diesel up to B30-325ml --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/66102540-nexpeak-obd2-diagnostic-scanner-obdii-nx501-vehicle-fault-code-reader](https://www.desertcart.pt/products/66102540-nexpeak-obd2-diagnostic-scanner-obdii-nx501-vehicle-fault-code-reader) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-03*
