by the looks of things if it's not the sensor in the first thread i posted it needs a new compressor which can get expensive if you don't want to go down the 2nd hand route

You need to check that the compressor is working or not, run a wire from it straight to the battery if it engages its ok you may have a wiring problem. I did I took it to auto elec to sort out it was not cheap. If not the compressor may need replacing you can get a second hand one for a reasonable amount .

Repeated cycling of the compressor is most usually low gas in the system. It might be a faulty low pressure switch but much more likely that the switch is tripping as the pressure is actually low.....

The system has got gas in it.If not this could be the cause
