Good afternoon
I own a C4GP 2010 and started getting a/c problems. the a/c works from time to time. the garage told me it was a problem with the BSM, I changed the BSM and the problem persists. they then told me to go to a Citroen service, which I did and they told me it was a problem with the ECU. I have the ECU part number 9667123380 but I can't find it cheap in Europe. are there other part numbers compatible with my engine which I can buy? thank you

What is the problem with the A/C?

sometimes it works, sometimes it doesn't, the blower works but no cold air comes thru the vents. i've noticed that it works when driving in the city (maybe due to the bumps in the road?). the compressor has been tested and is ok, the wires from the bsm to the compressor are ok, the low pressure and high pressure pipes have no leaks. i can upload a report from the garage if you are interested.
