Hello, I hope you can help me.. I’m looking for a way to read the error memory of my two cars cheaply (local workshops sometimes want horrendous prices for it). I don’t want to spend too much money, as I said a look into the error memory is really enough for me completely. Whether cable+software for the laptop or an app and an adapter etc. is really relative to me. I have a Polo 6N with new ZE and a Golf 4 both have OBD 2 plugs, but an old protocol which drives all workshop masters regularly to white gluten. Auto 1 Golf 4 bj 99 1.6 SR AKL Auto 2 Polo 6N1 bj 97 1.4 AKV Hope you have an idea what could come into question for me. Thanks already
