Hello Everyone. My wife has a 2013 Audi A1 Black Edition 2.0TDI. The air-con has stopped working.

Last year, I fitted an AC pump and got the gas replaced by a garage. It then worked fine all last year.

Now, on VCDS, I have two errors, which I would love some advice with please?

Error 1: 0051 High pressure sensor.
Error 2: 0143 Refrigerant Pressure sensor

I have attached some screenshots. Hopefully someone can tell me whether the pressure is correct or not to show whether there has been a leak or something else.

Does this mean it needs gas again, or is this another issue?
Many Thanks
Steve
