Complaint:
Active engine diagnosis warning lamp.
The following fault codes are stored in the engine control unit:
•
Fault code P245997
The regeneration frequency of the diesel particulate filter is not OK. System function is restricted.
•
Fault code P246397
The soot content of the diesel particulate filter is not OK, "The system function is restricted" is stored in the engine
control unit.
•
Fault code P245900
The regeneration frequency of the diesel particulate filter is not OK.
•
Fault code P246309
The soot content of the diesel particulate filter is not OK. There is a component fault.
•
Fault code P246385
The soot content of the diesel particulate filter is not OK. There is a signal above the permissible limit.
Cause:
The following causes may produce these fault codes.
For example:
•
Deviation detected in emission sensor system or sensor wiring.
•
Deviation detected in a component, which results in an excessive amount of engine soot development. (For example, intake air system, injector, HFM-SFI).

•
The fault codes for the regeneration frequency of the diesel particulate filter (DPF) appear when the vehicle is
regenerated unusually often or for too long. Normal regeneration intervals (driving distances between two regeneration periods) are 250 km urban and 500 km inter city. The duration of a regeneration period generally lies
between 15 and 25 minutes.
•
The fault codes for the soot content of the diesel particulate filter appear when the engine timing has calculated
an excessively high soot load. A high soot load does not necessarily actually exist. It could also be that faults in
the sensor system erroneously detect a high soot level, although the loading of the diesel particulate filter is actually OK.
Remedy:
For these fault codes there are guided tests in XENTRY, which have to be fully processed.
The following test steps are to be processed for the above-mentioned fault codes:
1.
2.
3.
4.
5.
6.
7.
8.
9.
10.
Read out and document the fault freeze frame data for each fault code from the engine control unit.
Record the performance data for the CDI control unit (under "Special processes" in XENTRY Diagnostics) or the
development diagnosis sheet (DAS).
Plausibility check of component B28/8 (DPF differential pressure sensor).
Check compression pressure (see AR01.00-D-1200WE for model 906).
Check installation height of fuel injectors (see AH07.16-P-1000-01S). Note: If there are any deviations, check
whether too many sealing rings or none at all have been installed.
Check charge air system for leaks.
Check exhaust system for leaks.
Plausibility check of temperature sensors in exhaust system.
Check electrical lines and connectors for emissions sensor system.
Perform wipe test on the exhaust tailpipes. To do this, take a suitable cloth (e.g. a soft cleaning cloth) and check
whether there are any soot deposits on the inside of the exhaust tailpipes (see attachment for example pictures).
•
If the cloth becomes black or gray, open the connecting point downstream of the DPF. If the exhaust pipe at the
DPF outlet is carbon-fouled, the monolith broken out or if a white crust is visible on the monolith, create a TIPS
case and coordinate any further courses of action with your relevant market support. (Please attach all the test
results/performance data to the TIPS case).
•
If no discoloration is visible on the cloth, perform a visual inspection at the DPF inlet. If the DPF inlet is oiled up
or the honeycomb structure of the monolith is partly/completely sealed with soot, open a TIPS case all and coordinate any further courses of action with your relevant market support. (Please attach all the test results/performance data to the TIPS case).
Note:
If the diesel particulate filter is replaced, this then has to undergo teach-in with XENTRY.
Regeneration while driving is not necessary.
In a warranty case all test results should be submitted along with the diesel particulate filter.
11. If no damage can be found to the diesel particulate filter, regeneration must be performed while driving, following
the test instructions.
12. Acquisition of diagnostic performance data, acquisition of data on completion of repair work
Note:
Please note that for the complete repair the damage code must relate to the component causing the damage.

If no faults are found, Create a PTSS case to coordinate further courses of action.
Replacement of the diesel particulate filter is not permissible in this case.
