Hello, I delete all the errors, then go to make a turn and recheck the errors that remain. probably you have some problem with the electrical system, I was on my audi a4 I had a lot of stupid mistakes type, the ecu is not recognized, the climate would not give diagniosi etc... I got by cleaning the contacts and the masses around the car and gave me the most problems.
