1.1 General notes on self-diagnosis
♦ The engine control unit has a self-diagnosis capability. Before
carrying out repairs and fault finding, read fault memory. Also
the vacuum hoses and connections must be checked (unme‐
tered air).
♦ Fuel hoses in engine compartment must be secured only with
spring-type clips. The use of clamp or screw-type clips is not
permissible.
♦ For trouble-free operation of electrical components, a voltage
of at least 11.5 volts is necessary.
♦ Do not use sealants containing silicone. Particles of silicone
drawn into the engine will not be burnt in the engine and dam‐
age the Lambda probe.
♦ Vehicles are fitted with a crash fuel shut-off circuit. This is in‐
tended to reduce the danger of a vehicle fire in a crash as the
fuel pump is switched off by the fuel pump relay.
♦ The system also improves the starting characteristics of the
engine. When the driver's door is opened, the fuel pump is
activated for 2 seconds in order to build up pressure in the fuel
system, note safety measures
