So I have a cts catch can installed and shortly after I notice I'm topping up my washer more frequently. I even had it to Audi to check for a leak. They could not find any issues. Now what I think is happening is that the fluid is heating up, and since it's now sealed with the new anodized filler cap, the fluid system builds pressure and gets released though the nozzle sprayers. I just want to confirm this with other people that are running the cts catch can.
