V60 adblue - matuuu - 06-02-2026
Hello,
I have an issue with the AdBlue system on my V60.
At first, I got fault code P20EE. I checked the injector and found that it was crystallized. I cleaned everything as thoroughly as I could using warm water. A few months later, the fault code appeared again, and I discovered that the injector was also leaking externally.
I bought a new injector, reset everything, and after that the system worked perfectly for about 4 months with no fault codes at all.
However, yesterday the fault code returned again, and when I removed the injector, I found the same situation as before. What could be causing this? How can I properly clean the AdBlue catalyst/SCR catalyst? Is it safe to simply flush it with warm water?
Thanks in advance for any advice.

The problem is the fluid itself - it crystalizes very fast. The same problem have all Euro6 cars, even trucks. One of possible solutions which usually I recommend for my customers to use ADBlue decrystallizer, for example this one: https://www.wynns.eu/product/crystal-clean-protect-125/

Thanks for the reply, it's worth a try.
Is it safe to simply flush the AdBlue (SCR) catalyst with water? I'm attaching photos showing what it looked like 4 months ago.
So, does this mean the injector should be cleaned every 6 months as part of regular maintenance?
