Super Mini ELM 327 V2.1 OBD2 Bluetooth Auto Car Scanner Diagnostic Tool OBD Interface OBD Reader

It took a while to connect this little thing with the mobile app. Once done when I tried to fetch archived codes (for nexon petrol), I would get no codes found. After 3-4 attempts it did pull up the code. Extremely helpful to decode the engine light problem. Not a replacement for a technician but good to know if you really need to visit a mechanic.

Doesn't connect to any device via bluetooth. I called Amazon they said they can't help me. The whatsapp contact provided on the company website isn't replying as well. I don't know why I bought this. Don't waste your money.

A solid four-star rating has been earned by the Super ELM 327 v2.1 OBD2 scanner. Vehicle engine fault codes are quickly read and cleared by this compact device, allowing check engine lights to be turned off without a costly trip to the mechanic. Real-time engine data—including coolant temperature and engine RPM—is smoothly transmitted to smartphones or laptops via Bluetooth. ​While exceptional value is offered for routine maintenance, a slight limitation is occasionally experienced due to the v2.1 firmware, as certain older vehicle protocols or advanced proprietary systems are not fully supported. Nevertheless, a highly convenient and budget-friendly diagnostic tool has been delivered here, and it is firmly recommended for any car owner looking to monitor their vehicle’s health.

A fantastic scanner of car if someone wants to get some basic information on the engine how it's working. There is little option to fix any issue for that we need a proper scanner. It's very easy to set-up and pair with the phone. It's a plastic build and quality is good.

I bought this Super Mini ELM 327 V2.1 OBD2 Scanner to fix a high RPM issue on my Maruti Suzuki Celerio VXI (2019), and it worked perfectly! The Issue: After I cleaned the throttle body myself, my car's idle RPM shot up to 1.2 - 1.4. The car was jerking at low speeds, and the exhaust manifold was getting red hot due to the high idle. Manual reset methods (battery disconnect/key cycles) did not work for me. The Solution: I connected this OBD2 scanner and used the Torque Pro app. I forced an error code by disconnecting the throttle body coupler while the engine was running. I used the app to "Clear Fault Codes." I heard a crackling noise from the throttle body (which meant it was calibrating). After a restart, the issue was 100% resolved! The Result: Idle RPM: Perfectly stable at 700-750 RPM. Drive Quality: Very smooth idling and no more jerking. Performance: The throttle response is now very sharp and much better than before. Savings: It saved me a lot of money and a trip to the authorized service center. I did the reasearch online and chat gpt and other AI were recommended v1.5 of this tool, I still decided to ahead with this V2.1 and it solved my issue in 10 minutes. If you don't know much, I recommend you to visit local garrage.

I bought this ELM327 auto scanner and used it with my Bajaj Pulsar N160 along with an OBD2 adapter. It connected properly and worked without any issues. I was able to scan the bike and check the ECU/diagnostic information easily. For the price, it’s a very useful tool for basic troubleshooting and checking error codes. Works fine with my N160 and OBD2 adapte
