Reason for block
Complaint:
- Engine warning lamp in instrument cluster
- Reduced engine power
- Fault code current/stored in CDI control unit
Cause:
Cause 1:
Iodomethane degassing from the pressure differential hoses (rubber) can be deposited on the differential pressure
sensor. Lifting (arrow) of the chip in the differential pressure sensor from the circuit board caused by the degassing of
iodomethane from the pressure differential hoses (see picture: 02.jpg).
Cause 2:
Contact fault in electrical connection of diesel particulate filter differential pressure sensor.
Cause 3:
Cooler of exhaust gas recirculation system blocked (see picture: 06.jpg).

Remedy:
Remedy for cause 1:
Safety notice: Risk of injury to skin and eyes when handling hot or glowing objects. Gloves, protective clothing and safety glasses must be worn when working in the vicinity of the exhaust system.
•
Replace differential pressure sensor (see: AR07.04-D-0006SD).
•
Replace all pressure differential hoses.
Note: The new hoses do not contain iodomethane.
Note: Disconnect pressure differential hoses from differential pressure sensor carefully to avoid damage.

In all cases the pressure differential hoses must be replaced and reordered! Do not use pressure differential hoses
from old stocks!
Remedy for cause 2:
1.
Remove air filter housing (see: AR09.10-D-1150SF).
2.
Separate electrical connection (1) (see picture: 03.jpg).
3.
Replace diesel particulate filter differential pressure sensor (B28/20) (see: AR07.04-D-0006SD).
4.
Replace all pressure hoses with hose clamps between diesel particulate filter differential pressure sensor
(B28/20) and diesel particulate filter (see: AR09.10-D-1150SF).
5.
Cut off wiring harness (2) approx. 10 mm before electrical connection (1) (see picture: 03.jpg at arrow).
6.
Cut new lines (3), to length "a" (approx. 150 mm) from the electrical connection (9) (see picture: 03.jpg).
Note: Fabricating the new lines (3) in the workshop is not permissible, as this can lead to more contact faults.
7.
Attach new lines (3) to wiring harness (2) with solder connector sleeves (5) (see picture: 03.jpg).
Note: Refer to the circuit diagram when connecting the new lines (3) (see pictures: 04.jpg and 05.jpg).
Special tools: Use special tools 220 589 01 99 40 (wire stripper), 220 589 04 99 00 (wiring harness repair kit
supplement for passenger cars) and 129 589 01 98 00 (welding pearl catcher).
Commercially available tools: Hot air gun.
8.
Insulate wiring harness (2) and new electrical lines (3) with fabric tape (see picture: 03.jpg).
9.
Plug in new electrical connections (9) (see picture: 03.jpg).
Note: The electrical connection (9) must lock correctly.
10.
Fasten new electrical wiring harness with cable tie (8) (see picture: 03.jpg).
Note: The cable tie (7) already on the electrical connection (9) must not be removed.
11. Install air filter housing (see: AR09.10-D-1150SF).
Remedy for cause 3:
1.
Check cooler of exhaust gas recirculation system.
Condition: Only if fault code 170400 is still present.
Note: If the cooler of the exhaust gas recirculation system is blocked, continue with step 2 below.
2.
Create a TIPS case.
Note: In this case a photo of the cooler of the exhaust gas recirculation system must be forwarded to the MPC.
