Hi everyone, on Monday night night when driving we got an engine management light pop up, followed by the ad blue light and “emissions fault” then about a day later it all disappeared, on Thursday it reappeared, then yesterday disappeared again. Having googled it , seems the most likely resolution is to have the whole tank replaced. Seems really crazy to have such a big issue on a car that has only done 32,500 miles. Is it possible the issue could be anything else? I have attached the error codes from the code reader. Thank you
P20A2 - DeNox system circuit - bleed fault - intermittent
P20E8 - pressure of the urea fluid. Urea fluid pressure too low - intermittent.
