Moin, I have read many articles, yet a short question: Climate cools at “normal” outdoor temperatures (e.g. 18 degrees) perfect – temperature in the air channel between 3 and 5 degrees. The clutch is coupling – compressor runs – at 3 degrees it goes out and at 5-6 degrees it is coupling again and runs along. In brutal heat it runs normally – it gets cold – after about 5 minutes and that unfortunately stays the same. After a certain service life it is the same. Can it lie on the coolant? Actually, the The plant was filled half a year ago because the LLK came new and the climate cooler was out. But I don’t trust the roasting completely. So let the first measure do a climate service, or first check something else?
