Background
Driving in a combination of high external air temperature and high altitude can result in a too high turbo speed. This can in turn cause permanent damage
to the turbo. In order to protect the turbo, new software with improved overspeed protection has been developed.
Symptom description
Turbo damage
Procedure
Before proceeding, check box B4 of the modification identity plate. If the box is not marked, proceed as follows.

SPS programming Trionic 7
12 Volt current requirement for programming
It is essential that the battery is in good condition in order to carry out successful SPS programming. Before work is begun the status of the battery must
be checked. This is done with 86 12 525 Battery tester. Follow the battery tester instructions. Remove the car's main fuses by the battery in order to
eliminate system noise during the test. Fit the main fuses after the battery test has been carried out.
If necessary, charge the battery with low level current (less than 15 A) at the same time as SPS programming is carried out. Avoid rapid charging (above
20 A) as this can disrupt SPS programming.
