TOPDONAL400-A OBD2 Code Reader, 10 OBD2 Functions, Check Engine Light/Smog Emission Test / O2 Sensor Test/EVAP, Free Lifetime Update

Nice touch is the LED lights to make it easier to connect. Read codes and clears them and some useful info. Had a bluetooth one before which stopped working so bought this one instead and does the trick for European cars but won't read all the car info on my American muscle car

The media could not be loaded. This is great for finding out fault codes on any make and model of car (providing it has diagnostics port which all modern cars have) it’s really easy to use with very good clear and simple to follow instructions and very minimal buttons it’s made well and is rechargeable too its great for finding out what’s faulty with you car before taking it to the garage for repair so you know exactly what to expect and that way your already one step ahead it also is a brilliant bit of kit if your buying used cars because you can take this with you to check the car for sale for any known faults on the cars computer so it could save you buying a complete money pit its a really great tool to have for car owner or buyer and I would strongly recommend buying one for the small price it could save you big in the longer term highly recommended

Product works really well very quick with the code checks, however does not have the led light on the plug as advertised other than that great little piece of kit

Very good product.Not too expensive.Does everything I need it to do.Would buy again.

I purchased this item to reset airbag light in our car but after many tries I gave up, because this device was unable to scan any code. Not even engine light. Cheap is cheap but waste of time and money.

This is good quality and provides lots of information about the car ( A 2012 1.7 litre Diesel Vauxhall Astra). I bought this because I was getting a message to service the car soon, even though it had been serviced recently. Vauxhall wanted a lot of money to just read the code! I bought this and it told me there were no codes stored. I also had this problem with the first one I bought and returned. I took it to my local garage and they diagnosed it as a Glow Plug issue from the code they got. I don't know if this could not read the code because it is specific to Vauxhall or not. I'm assuming that if I had the engine management light lit on the dashboard then maybe it could have read the code. The sellers tried to help by asking me to send a video of what was happening and to let them know which code the garage saw so that they could investigate. Unfortunately, by this time the car was already being repaired at the garage and they could not remember which code they saw!

I was getting an intermittent engine management light on my 2009 Nissan Primastar 2.0 dci, which would flicker when driving along but never stayed on.Used a Bluetooth reader and apps but nothing was coming up so had no idea what was causing the fault.Tried this unit and at first it didn't find anything, so decided to leave it plugged in when driving and if the light came on I would pull over and safely run a scan.Ideally the light came on so pulled over, and straight away it pulled up a P0340 code. This was just a camshaft sensor so a £20 part and easy to replace, so saved me a few quid in getting the garage to run their diagnostic at £50 a time.The only thing with this tool is it doesn't show historical codes, so will only show codes when EML is on constantly, or (in the case like mine when the light is intermittent) if you plug in and scan before turning the engine off. But I guess that's a feature of more expensive units.Easy to use and runs very quick, glad I have it in my glove box

Good quality easy to use
