I think I know the answer to my problem and I think it’s bad but I am hoping someone can offer a more optimistic analysis of my problem.
After a year of inactivity I wanted to take my 2017 320s for a weekend of camping. I checked to be sure all valves were set correctly, filled the fresh water tank, turned on the pump and started to check for any leaks when I heard water streaming underneath the camper. I saw green colored water (glycol) streaming from a drain on driver side behind the wheel. I opened the Alde compartment and saw green water flowing through the clear plastic tubing. I then opened the panel to the Glycol reservoir and saw that the reservoir was full to the top, I thought that was strange since I always maintained it at the Max level line. I pumped out some of the fluid and when I turned the water pump back on I saw the reservoir fill up again. I did that couple more times with the same result. Any thoughts?
