Refrigerant loss – sporadic

Moin together. Today, the climate really annoyed me. With 4 men from Frankfurt to Hanover and the climate doesn’t do. For this, the fan constantly blew at full power in order to fight against the sun at all. Before that, I read out the fault memory and there was exactly one error in it: Refrigerant loss – sporadically My research shows so far, that it can be that the pressure sensor (sporadic) has failed (wire? Sensor itself?) and therefore the compressor no longer switched on until the error is deleted. Now, however, I shrug back to just delete the error. I still have a guarantee… Tips from the experts? Otherwise, tomorrow morning I sit on the seller’s lap Edith: more did not give me the SuFu, except that apparently the amount of coolant can be a bit too low.
