I am currently driving a 2019, 2.0 tdi Superb with 77k on the clock.
The vehicle has been regularly serviced and runs perfectly.
Every 400 miles or so the engine management light comes on with the following codes:
P2002 and P20EE.
They relate to nox emissions, bank one.
The dpf seems fine according to the vag dpf app and the differential pressures look ok.
Regen's are every 170 miles or so with town driving and complete with around d 5% soot content left.
I am thinking it may be possibly be one of these three issues:
Faulty nox sensor
Partially blocked adblue injector,
Worst case scenario is blocked egr cooler although there are no codes showing to suggest this.
Has anyone else encountered these codes as I am reluctant to pay the dealer £120 for a diagnostic.
Looking through other forums regarding these codes some cars have had many parts replaced only for the codes to still be there.
