Hi Yani,

Have you solved this problem in v3.3?

Ok, we are waiting

I faced to the same problem on same car.

Hi, Glad to upgrade FES to 3.2 version, because there are more options for climate control unit. But I'm not able to do actuator tests. I received message 'test failed'. What I'm doing wrong?

I purchased registered version of FES and I'm disappointed. There is no possibility to see climate control parameters or to make some actuator tests. I'm talking about AR 156 '02.

It would be nice to have such possibility.

I'v got 2003 Alfa 156 JTD. Is it possible to connect to climate control unit?
