Good afternoon all, I have a question re a couple of OBD2 codes encountered on a C3 Picasso 1.6 Blue HDi (16 reg): P20F6 Denox System Circuit and P3053 Urea Line Pressure. Any thoughts of what could be the cause of both of them appearing simultaneously would be much appreciated. Many thanks in anticipation.
Cheers

Hi, and to the forum. I am not familiar with the C3, but the Nox and Urea errors look like they are to do with the AdBlue system. However, if you wait a while somebody with far more knowledge than I will be able to give you more information.

Yes, I am paranoid, but am I paranoid ENOUGH?

Thanks a lot James, and in anticipation indeed to anyone who might have seen these two before simultinaneously or have any further thoughts on the matter. In particular could these two be symptomatic of a blocked AdBlue diffuser (or worse, something to do with the AdBlue tank - although I have never had the AdBlue topup indicator on)? Cheers

Is the engine management light on, or is it saying top up in x miles?
You need a bit more to go on than just the fault codes, you need to be able to see the live data to see what is (or isn't!) going on.
