Engine control system

(EOBD) failure

(optional for versions/

markets where applicable)

Normally, when you turn the ignition

key to MAR, the warning light must

come on but must switch off when the

engine is running. It initially lights up to

indicate that the warning light is working.

If the warning light stays on permanent-

ly or comes on when the car is moving:

1) With a fixed light - indicates

that the supply/ ignition system is mal-

functioning that could cause high exhaust

emissions, possible loss of performance,

bad driveability and high consumptions.

In these conditions, you way continue

to drive while avoiding asking a lot from

the engine or high speeds. The prolonged

use of the car when this warning light is

on could cause damage. Contact an Alfa

Romeo Authorized Service Station as

soon as possible. The warning light turns

off if the malfunction disappears, howev-

er the system stores the warning anyhow.

U

2) Flashing light - indicates that the

catalytic converter could be damaged

(see paragraph on “EOBD System” in

this chapter).

If the warning light is on and flashing,

take your foot off the accelerator and dri-

ve at low speeds until the warning light

stops flashing; continue travelling at a

moderate speed trying to avoid driving

conditions that could cause the warning

light to flash again. Contact an Alfa

Romeo Authorized Service Station as

soon as possible.

If, when turning the ig-

nition key to MAR, the

U

warning light does

not switch on or if, when dri-

ving, the light flashes or emits a

fixed light, contact an Alfa

Romeo Authorized Service Sta-

tion as soon as possible.

Engine control system

(versions for markets where

applicable)

1) In normal conditions, turning the ig-

nition key to MAR, the dial warning

light turns on but it should go off when

the engine has started. The initial turning

on indicates that the warning light is

working properly.

2) If the warning light stays on or turns

on when travelling, it indicates a fault in

the supply /ignition system which could

cause high exhaust emissions, possible

lack of performance, poor handling and

high consumption levels.

In these conditions, it is possible to con-

tinue driving without however demanding

heavy effort or high speeds.

Prolonged use of the car with the warn-

ing light on may cause damage. Contact

an Alfa Romeo Authorized Service as

soon as possible.

The warning light turns off if the fault

disappears, but it is still stored by the sys-

tem.
