Digital Engine Control Module DME 7.1.1

Location of DME control module







DME 7.1.1 is a proven, highly reliable engine control module, which was specially adapted to suit Porsche requirements. It is located under a cover in the right-hand part of the plenum chamber (engine compartment) and is protected against penetrating moisture.

Unlike the DME control modules used previously at Porsche, the fault memory is retained even after the battery is disconnected. It is especially important to bear this fact in mind when installing control modules as a test and then returning them to storage or installing them somewhere else. In cases such as this, the fault memory must be erased again before removing the control module.

When the voltage supply is interrupted, the following control module values are deleted:
- All adaptation values
- Learned values of the throttle adjusting unit
- Ready statuses of the individual diagnostic routines (see following chapter)
- Freeze frames stored with the faults (ambient conditions; see following chapter)

Bear in mind that programming the DME (e.g. loading a new data record) will also delete the values mentioned above.
