  • Unbeatable value, works for foreign cars well
Size: S
The Autel MS309 is one of those tools every car owner should have. It was super easy to use, quickly read my check engine code, and saved me a trip to the mechanic. Compact, reliable, and perfect for basic diagnostics at home.

  • Good product/QR code bad
Size: S
Was going to write (with one star): MaxiScan MS309 is not on the manufacturer website. It is not listed in the current products nor in the legacy tab, which means no user manual. But, I was using the included QR code on my phone, and that site must be outdated? Went to their webpage on laptop and MS309 is supported with downloadable user guide. I have a new gas cap and had Trac Off and Check Engine lights on Tacoma. MS309 gave me 2 codes related to that (P0441 and P0455) with description. MS309 worked great and easy and on first try. ... show more

  • Must Buy/Have Item for Everyone Who Owns a Vehicle(s)
Size: S
This device is a must have! Self sufficiency is power. I have an exotic foreign vehicle and the OBD2 scanner works perfectly. I don’t have time to go to the dealer or wait on anyone. I detected the issue, cleared the check engine light - since I know it’s safe to drive temporarily until I get to the dealership. This tool is great for everyone - especially women and first time car owners. It will save you money and time because you know exactly what the issue is that needs repairing. No one will be able to pull wool over your eyes again. Durable and easy to connect. Great purchase! ... show more
