General notes on the injection system

Repairing the ignition µ Rep. Gr. 28.
The engine control unit is equipped with a self-diagnosis
system. Before repairs and also for fault finding, first of all
interrogate the fault memory. Also check the vacuum
hoses and connections (unmetered air).
A minimum voltage of 11.5 V is required for perfect func-
tioning of the electrical components.
If after fault finding, repair or inspection of components
the engine starts briefly and then stops, it is possible that
the immobiliser blocks the 4AV control unit. In this case
the fault memory must be interrogated and if necessary
the control unit must be adapted.
Certain inspections may cause the control unit to detect
and store a fault. It is therefore necessary to interrogate
the fault memory after having completed all inspections
and repairs, and if necessary erase µ Chapter 01-1.
