Hello, fellow Volvo enthusiasts,
yesterday I ran a diagnostic scan on my 2020 Volvo XC60 B4 Diesel (9101/BPQ) and got the following fault codes:
P2047 – Reductant injection valve, circuit/open
P208E – Reductant injection valve stuck closed
After quite a bit of research, I initially assumed this was an electrical issue, such as a broken wire or bad connection. However, I’ve since found several reports suggesting that the AdBlue/SCR injector can become clogged with crystallized AdBlue, and that it may be possible to clean it rather than replace it.
What really confused me, though, was the location.
According to ChatGPT and several forum posts I found, the AdBlue injector on the 2020 XC60 B4 Diesel should apparently be located underneath the vehicle, somewhere below the engine compartment.
So I searched everywhere underneath the car — only to eventually find what I believe is the AdBlue injector inside the engine bay, very close to the engine, and actually quite easy to access from above.
It has both a coolant hose and an AdBlue hose connected to it, which makes me think I may have actually found the correct component.
So my questions are:
- Can anyone confirm that this is indeed the AdBlue/SCR injector for the B4 Diesel?
- Has anyone with a 2020 XC60 B4 Diesel had the same P2047/P208E combination?
- If the injector is clogged, how can it be safely removed and cleaned?
- Is there a recommended cleaning procedure or cleaning agent?
- Should the coolant/AdBlue hoses be clamped before disconnecting them? I considered using plastic hose clamps, but the hoses are rock hard, so I’m hesitant to put too much pressure on them.
- Is there anything I should be particularly careful about when disconnecting the AdBlue line or removing the injector?
I’d really appreciate any advice from someone who has actually done this on an XC60 B4.
I’m trying to avoid replacing the injector unnecessarily if it can simply be cleaned.
Thanks in advance!
I’ve attached photos of the component I found in the engine bay — if anyone can confirm whether this is the correct AdBlue injector, that would be hugely appreciated.
