I have a B180 CDI - 2008 (W245), the A/C stopped blowing cold and was regassed, it worked fine. When the hot weather came I noticed it was no longer blowing cold again, in between the regass and it stopping again, the battery had died as the lights were left on.

I had the garage look at it and they said everything is fine, but the compressor is not receiving a signal to start and that they believed it likely needed a mercedes diagnostic device to reset it.

I found instructions online for several Mercedes models but non that matched the B180 W245. I tried to hold the defrost and recycle button at the same time, but the led's never lit up and flashed as per the instructions.

Anybody know how I could reset it myself?
