Is it possible to downgrade dde ecu because after update in BMW there is always fault P2002. DPF was changed with original new one. Made some test on air mass an there is small correction between setpoint and actual, injectors are in good condition, egr is in good condition acording to ista test plans.
Everytime same fault and I think the only possible reason is that they updated software.
