U480 1.5" LCD Universal CAN-BUS OBD2 Car Diagnostic Code Reader Memo Scanner

Pros: - Works ok with my 2006 VAG car. Can read the failure codes - shows also the OBD self-tests, whether they have been passed or not. It is very useful to check these before inspection - clears correctly the failure codes and turns off the annoying yellow engine symbol from dashboard - good manual, describes the fault codes - very easy to use - no need for battery - well build, feels solid

Cons: none

Other: Works ok with newer VAG cars (VW, Skoda, Audi, Seat)

Pros: Very easy to use and has good manual which lists all kind of codes (hundreds of them). It supports many diagnostic protocols. When connecting to car, it goes thru the diagnostic protocols and uses the matching one. It worked even with a ten years old Lada Samara (amazing) and listed all the engine and ignition problems it had. Build quality is good, it feels solid. Works also fine with VAG cars.

Cons: A bit expensive as it's basically a simple device.

Other: You should have one in your glove box.

Pros: This was the cheapest OBD2 I could find that looked like it might have some nice features. Easy to clear CEL codes by erasing them.

Cons: Has minimal features. Shows only generic codes, it is best to look up the code specific to your car

Other: I bought it when it was $35, now its $22, so you can't find anything cheaper at a car shop or hardware store here in North America
