Citroen Jumper/Relay III - DPF error

Unread post by seba65310 »

Hello,
I have a problem with Citroen Jumper III, engine: 2.2 HDI 150 PUMA C
VIN: VF7**************[VIN obfuscated, can be read by forum staff]

The program reads the following errors:
P0423-92
and
P2002-7A

The DPF was washed, but it didn't change anything.
Where to look for the cause?
Will replacing the fuel injector help? Does it need to be specially programmed?

When you had the DPF cleaned, you must tell the engine ECU the DPF has been replaced - otherwise it will not know which concerns the second code, but also the first code concerns the atomiser of the fuel at the exhaust:
Fault Code: P0423 92
