Catalytic converter, exhaust

Catalytic converter for petrol engines
Leaded fuel will damage the catalytic
converter and parts of the electronic
system, rendering them inoperative.
High quality fuels other than those listed on
pages 158, 268 (e.g. LRP
1)
) could damage
the catalytic converter.
Damage to the catalytic converter or the
vehicle may result if the following points
are not observed:
z
If you experience misfiring, irregular
engine running after a cold start, a
significant loss of engine power or other
unusual problems that may indicate an
ignition system fault, seek assistance
from a workshop as soon as possible. If
necessary, continue driving for a short
time at slow speeds, keeping the engine
revs low.
Irregular engine running and a loss of
engine power when the Electronic
Stability Programme (ESP®
Plus
)
3
comes
into action are the result of operating
conditions and are therefore of no
significance – see page 166.
z
If unburned fuel enters the catalytic
converter, this may result in overheating
and irreparable damage to the catalytic
converter.
You should therefore avoid
unnecessarily long use of the starter
when starting-off, running the tank dry
(an irregular fuel supply will lead to
overheating) and starting the engine by
pushing or towing.
z
If the control indicator
Z
for exhaust
gases flashes, slow down until the
flashing stops and the control indicator
illuminates. Contact a workshop for
assistance immediately. Control
indicator
Z
for exhaust gases –
see page 162.
