Technical Bulletin
Service
When diagnosing a vehicle with the fault P0401 perform the following:
 Remove the EGR filter from the DPF and swipe the inside of the exhaust pipe at the EGR filter connection
point using a clean cloth or your finger. See figures 1 and 2 below.

Figure 1

Figure 2

If your finger or the cloth comes out with black soot, replace the DPF & EGR filter together.
If there is no soot on your finger or the cloth, continue with GFF diagnostics, this bulletin does not apply.

Note:
When replacing the DPF for the fault P0401 it is important to replace both the DPF and the EGR filter together, as
soot accumulation in the EGR filter is undesired. It is NOT necessary to replace any other components for this
fault (i.e. NOx Storage Catalyst, Sulfur Catalyst, Exhaust Flap, EGR Cooler), these components should be
reinstalled in the vehicle with the new DPF and EGR filter.
Refer to Tech Tip 2035501 (TT 26-13-02) if you are unable to perform a regeneration after the repair. The
soot level adaptation may need to be reset.
After installing the new DPF and EGR filter, ensure that the ECM has been programmed to the latest version. The
updating of the ECM should be charged to the appropriate UPDATE or Technical Bulletin.
