This could be a number of different things. The Klima relay, compressor speed sensor, slipping belt, bad high pressure switch, the ACC itself. if the system pressure is too high or the high pressure switch is malfunctioning, there is nothing that the low pressure switch will do to get the compressor turning. If the compressor is not engaging long enough to pressurize the system, the bubbles will persist. Troubleshooting should start with the simple stuff, belt slippage, high pressure switch, proper system charge and a good read on the pressures when and if you can get the compressor to stay engaged long enough to get a reading. A static pressure read on the low side might be useful (maybe). But, I think you might have to sub or replace the ACC to eliminate that component because it interacts with all of the other components.

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
