Reg 56 - Aircon Electronic issues

[Billias]

Hi,

I do have an Megane II 2.0T petrol. (not the gt). I bought it second hand, it have had some A/C Issues.
We refilled it with a specialist, and then It was not kicking in. We reset the Errors on a Renault (clip) and then everything was fine.
AFter a few days it went back to numb state (nothing was happening). The A/C pressure was ok. and from the Renault they wanted to replace a Cable connector, as they said the A/C was replying with funny messages to ECU (funny answer, from the Renault Dealer). AFter they did it, 2 months after it happened again....
Then i went to the dealer and they said: we have to replace compressor, due to a problem to the electronics of the compressos, as my ECU gets strange/funny messages.

What is your opinion on that? Is it common? (i couldn't find something)
