Hello, I will describe here my problem, which should probably be known to many, or already there are some threads to it. I noticed with my S60II D3 already last winter the coolant missing, or has a loss. This was 2015/2016 in the winter. Haber thought nicely after thought ok will be ok. About the meagre spring,summer until autumn was nothing…Now now on the cold days, for a few weeks, I have again coolant loss… When I open the lid slowly,zie The hose is also very hard, and after pressure check after Volvo say immediately, no D3 engine is known with ZK problems…If the first…wanted to make ZKD immediately,without CO2 testing. In addition, I have the feeling that the Volvo does not pull asoo as before…come up to 200 km/h…with ach and krach…wasn’t like that before… Then I went to the workshop around the corner…This one has a little leaky it tested….negative Then CO2 test done….negative…. now I should just drive like this… Or do I just want to have ZKD done for expensive things like this? Since it could not be determined… Therefore my question: has someone possibly had the same symptoms? Is what known? Am really desperate with the cart… For answers and advice I am grateful… Gruss Enekin….
