Thread: P2BAE-00 and 02 NOx Exceedence Faults

Hi all, An orange engine light appeared the day following a service and the diagnostics shows P2BAE-00 NOx Exceedence and P2BAE-02 Nox Exceedence errors. Service centre reset the faults however they re-appeared the following day. I note the service incl. an Adblue top up however I had not had any low Adblue warnings recently (I topped up about 6 weeks / 2,500km ago). The car seems to be performing normally, no smoke etc. Google suggests that this is either a wiring fault, a DEF pump fault or simply an overfill of the Adblue tank? I think it very odd that this all happened within a day of the service... Any thoughts and feedback appreciated. Thanks,
