"Engine Fault: Repair needed" and Adblue warning

Unread post by Olumide »

Last December the AdBlue warning came on on my dash. Following this, I poured a large quantity of AdBlue into the AdBlue tank and everything was fine -- for about a month and then suddenly the "Engine Fault: Repair needed" and Adblue warnings come on. These warnings come on as soon the dash is powered on and are followed by three beeps.

I've taken the car to two mechanics and they say the same thing. Diagnostic shows loads of fault codes, but the most relevant is P20EE 00 (DeNOx system depollution). On both occasions the fault code was cleared but the warnings came back after a few days.

I am at a loss of what to do. Please advise.

Needs someone with a decent scan tool - and knowledge to use it! See my post in there about what it should do, which should then give a clue as to which part is at fault.
