Hi all

Does anyone know what this code means or how I can explore further - what I need to look for?

The aircon works but on a long drive seems to occasionally then blow warm for a bit.

The code is described as “The Power Supply is too low. The signal amplitude is less than the minimum amplitude”

Could it be the clutch slipping or something?

Many thanks!
 
Just take the car to aircon outfit, new gas required?
I could try an aircon place. I topped up the gas earlier this year but will check it. The aircon does work and blows cold most of the time, it’s weird it just seems to be on longer trips when it starts to work intermittently. And I can’t seem to find what this fault code might relate to.
 
When you get the aircon fixed use it all the time hopefully no more problems.
Aircon on my 05 CLK has never been repaired/re-gas.
I think I will get tested next year as I think the performance has dropped off a bit.
