Concerns:

DME control unit:

- Fault code P2080/2081/2082/2083 (exhaust temperature sensor).

Information:

- Complaint: Low engine power,

- Maintenance and/or repair work,

- Vehicle diagnosis using PIWIS Tester 9718.

It is possible that the fault codes specified above will be displayed in the DME fault memory during vehicle diagnosis in the course of maintenance and/or repair work.

In addition, the customer may find that - in conjunction with the fault codes - the engine does not have enough power.

The fault memory entry is caused by the exhaust temperature sensor (referred to below as sensor").

Action Required:

Until further notice, the following procedure applies in the event of a complaint:

Disconnect the electric connection between the sensor control unit and the DME control unit at the sensor control unit and fit an "empty" connector housing on the wire harness on the DME side. Do not replace the sensor.

This measure has no effect on the engine's emissions, power or component protection.

We will let you know what further action is required at the relevant time.

Installation Position:





The sensor control unit is installed in the rear left of the engine compartment (-arrow-).

Material:

The following parts from the cable repair set Nr.155-1 Pos.1 are required for this measure:





Cartool No. 96 0 131, 4-pin housing (1 required) (-A-).
Cartool No.96 0 453, dummy plug, green (4 required) (-B-).

If your cable repair set does not include the specified parts, you can order them from the parts department under the following part numbers:
