Our KW850 full-function obd2 diagnostic scan tool is capable to identify the O2 sensor issues, in our diagnostic menu, you will see the O2 sensor test results status and how many O2 sensors are supported as well, so i'm sure our obd scanner KW850 will help you to locate which sensor need to be replaced. Many other scanners may only shows a trouble code but did not refer to which part is failed, but our scan tool includes more function like O2 sensor test, On-board monitoring test, Evap test, which is quite useful at some time, by the way, KW850 is supporting your bmw 328i from 96' and after universal obd2 vehicles. **Q: Does it test car batteries?** A: You need a battery tester to test a battery actor. It can tell you if it's charging but that's about it not tested. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Dummy proof *by G***R on August 6, 2021* Awesome scan tool that anyone can use to check and clear the dreaded check engine light. I've owned the more advanced much more expensive scan tools and this one def gives you more bang for your buck!!! It does everything one 3x's the cost does with complete ease. Large screen that is very easy to read, easy to follow directions, a complete library of codes, a search option, will provide graphs if desired, has a print featureand real time data you can track while driving! I couldn't be happier!!! I'm gonna be sending some out as gifts!! ### ⭐⭐⭐⭐⭐ Great Product! *by X***N on October 5, 2019* I searched many similar products and decided to buy this one for its features/price/good review. This tool is a must have for old car owners. It is easy to use and provides more useful functions and features than the OBD2 Scanner I had before. It is a handy tool when your car's check engine light turns on. It will save you time and money. One feature I like the most is the I/M Readiness, which will tell you if your car is ready for Smog Check. I also like the Battery Test function and the extra-long cable. I tested it on my Camry and Odyssey. It worked great! ### ⭐⭐⭐⭐⭐ good quality, reads accurately! *by B***M on April 15, 2018* My husband was so excited when this showed up! We have a Passau with a gas engine, and it has been acting up a lot lately - moreso it seems on his way to work, so he has been doing some easy fixes on his lunch breaks. That being said he has to know what is wrong, so we got this to he in his car so he can read codes. The great thing is this one displays both the code and what the code means. It also is quick and easy to use. He does wish it had a battery operated option, but that's not a big deal in the end. It seems to be good quality. It read accurately on our latest issue, was quick, the rubber and plastic seem to be nice quality. Also, the screen is very clear. My husband's favorite feature is the nice carrying case. The details matter. :) ## Frequently Bought Together - KONNWEI KW850 Professional OBD2 Scanner Auto Code Reader Diagnostic Check Engine Light Scan Tool for OBD II Cars After 1996(Original) - KONNWEI KW208 12V Car Battery Tester, 100-2000 CCA Load Tester Automotive Alternator Tester Digital Auto Battery Analyzer Charging Cranking System Tester for Truck Marine Motorcycle SUV Boat - KONNWEI KW310 OBD2 Scanner Full OBDII Functions 10 Modes Automotive Engine Fault Code Reader Scan Tool for All 1996 and Newer Cars (Red) --- ## 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.be/products/83652821-kw850-professional-obd2-scanner-auto-code-reader-diagnostic-check-engine](https://www.desertcart.be/products/83652821-kw850-professional-obd2-scanner-auto-code-reader-diagnostic-check-engine) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-28*
