My air con history is as follows:
New compressor
All sensors changed
Climate computer replaced
Re-gased numerous times (no leaks)
No visible alarms

WHY DO I HAVE NO AIR CON?

Just a thought, have any fault codes relating to the A/C been cleared.
Sure I read somewhere this had to be done to get it functioning again.

Who diagnosed what was needed, who fitted the parts and what guarantee did you get with the work?
You say air con history so I guess this has been dione at different times. Was is by the same company or various?
Were you ever shown it working after a repair was completed?
Sorry for the questions but I can't see why you have that history and still not working, assuming that you paid for the completed work.
I was wondering if you did the work yourself but not sure changing a compressor is DIY stuff.

It couldn't be tested the last time as it was too cold (just a month ago)
I'll be contacting the workshop again on Monday. As you can imagine, I'm really disappointed.
Gonna check a few more things this weekend ie,
Is compressor actually engaging, is there a fuse and maybe clean the condenser.

Update. This morning I proved that no power is going to the compressor. When I applied 12v manually, it activated and I get air con. Fuse is Ok so I guess my next hunt is for a relay or a broken wire.
Does anyone know if there's a relay and if so where is it?

Having a similar issue myself, no fault codes, I can hear the compressor anyway , regassed the end of last year. Just not getting cold!
Might let MB loose on it since it’s under warranty, see how clever they are ;)
