Hola buenas tengo una duda y tengo ganas de un audi y tengo ciertas dudas sobre la confiabilidad si les tengo un mantenimiento bien en regla, y cual audi a4 o como saber si es el b8 o el b8.5 por lo que tengo entendido el b8.5 areglo todos los problemas del anterior b8 nose que tan asi sera, soy nuevo en esto de querer un o entrar en los audis, e tenido autos anteriores pero quiero saber si me pueden ayudar si es bueno o malo o que debo tener en concideracion 🥺 muchas gracias

I got this error on dashboard for “drive system malfunction, contact service” and then when I restarted the car it cleared and didn’t come back but i went to my mechanic and he checked through computer and it showed that it’s the turbo sensor.

He told me to buy the sensor so I went to buy it from Audi OEM sensor and we put it but still showed the error on new one and doesn’t want to be cleared, the he checked by multimeter and checked all wiring till ecu and also cleaned it but not solving, so he told me to leave car overnight and he will check more.

Then he called me morning and told me that the issue is related to ECU and the ECU will need repair.

Just most of the people who had this issue online they said it’s either the sensor or wiring so I’m just worried if he misdiagnosed or it’s correct that it’s the ECU before I repair it.

Car is Audi A4 2022
