Aircon

[mjclegg23]

Hi,

Looking for thoughts.. I have a 2018 A5 sportback 2.0Tfsi...I've just returned from a 6hr drive to and from Cornwall the car never missed a beat..just aircon issues hoping its not anything more than a re-gas..after 3hrs of driving the blowing slowed down and the sir became warmer, turned the blower up to full and the airflow was very low, then a musty smell, which I presume is the aircon needing to be re-gassed.. small trips during the week no problems with the airflow or temperature but yhen the return trip home and after 3-4hrs the airflow was low and temperature warmed up..could this be a re-gas?, motor?, compressor?

Thanks in advance

That the air flow reduces suggests an electronic problem. Best to get the system diagnosed.

Yes thanks, not what I was hoping to hear..was waiting for any other comments..cars in for it's MOT 11th so good to know that it could be the electronics so I can expect that

Thanks

It may be a control problem or a vent motor fault. A diagnostic scan on a professional machine should identify it.
