Andrzej Posted June 3, 2020 Share Posted June 3, 2020 Hello Audi A6C6 2.0 tdi, 2010. There was a problem with the climate not working and the fans that run all the time. When the engine starts, they turn on when they turn off and go out. After connecting the computer he showed the error: 00256 - A / C Pressure / Temperature Sensor - G395 No signal / No communication. So I replaced the temperature sensor - nothing helped. I also replaced the pressure sensor and after this replacement the computer showed two errors: 00256 - A / C Pressure / Temperature Sensor - G395 Not A Plausible Signal and the second: 01844 ECU For Fresh Air Blower - J126 Not A Plausible Signal. Further, the air conditioning does not work and the fans run for time. Has anyone in the forum had such a case and what could be damaged. Thank you in advance for all your help.
