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.nz/products/83652821-konnwei-kw850-professional-obd2-scanner-auto-code-reader-diagnostic-check](https://www.desertcart.nz/products/83652821-konnwei-kw850-professional-obd2-scanner-auto-code-reader-diagnostic-check) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-05-31*
