A5 2019 2.0TDI - P2002 error

[Thomson_adam]

Hello all

i have recently purchased a 2019 Audi a5 2.0tdi 190 with 106k on the clock.

i bought the vehicle from a colleague who used it for motorway miles. 

recently I have had an engine management light come on and with my basic code reader I can see it’s a p2002 error. After a reset the code came on after around 250 motorway miles.

my friend isn’t a car guy but he did say he’s had a sensor changed recently and I can a turbo pressure sensor and exhaust pressure sensors have been recently changed via invoices. Do you think it’s the EGR cooler ?

If the code is relating to a egr cooler then it could be.

Is says the dpf is below efficiency but after reading the forums it seems to come back to the cooler
