Exhaust emissions test for petrol en‐

gines without OBD

Note

♦ All test conditions and data required for exhaust emissions

test: ⇒ Data sheets for exhaust emissions test

♦ The ignition timing is determined by the control unit and cannot

be displayed. Adjustment is not possible.

♦ Idling speed and CO content are not adjustable (check only).

For deviations from test value: carry out repair measures.

♦ The CO content is regulated by the lambda regulation. Faults

in the lambda regulation are detected in self-diagnosis and

stored in fault memory.

♦ Faults identified (engine electronics) when fault memory is

read must be rectified and the fault memory then cleared.

♦ To prevent injuries to personnel and/or damage to ignition and

injection system, the ignition system wiring (including high

voltage wiring) should be connected and disconnected only

with ignition switched off.

Special tools and workshop equipment required

♦ Exhaust emissions station - VAS 6300-

♦ Adapter for older vehicles - VAS 5051/2-

The visual check is displayed with the request to connect the di‐

agnostic connector -arrow A-

– Follow instructions on display -arrow A- and -arrow B-.

– Connect diagnosis cable connector to EOBD connection.

Conditioning:

– Start engine.

In the conditioning phase the engine and, if necessary, the emis‐

sion control systems are brought to operating temperature by

throttle bursts and are prepared for the exhaust emissions test.

– Follow instructions on display.

– Maintain engine speed in required engine speed range.

If no conditioning is necessary, press → button -arrow- for the next

measurement.

Measuring engine temperature:

5. Exhaust emissions test

Lupo 1999 ➤ , Lupo 3L 1999 ➤

Maintenance - Edition 03.2018

It is automatically switched to display for measuring engine tem‐

perature.

– Follow instructions on display.

Note

♦ This is only indicated on display if engine temperature has not

reached 80℃.

♦ Do not insert emission probe into exhaust tail pipe.

♦ Using button “Alternative input” -arrow- other measured value

inputs can be selected to measure the engine temperature.

The measured value must then be entered by hand. At end of

exhaust emissions test the measured value is marked by # in

the evaluating mask and in the log print-out.

♦ The button “Alternative input” is only active, if previously a dif‐

ferent method has been selected at specified data input for

EET for “Engine oil measurement”.

Caution

Measuring the engine temperature is normally carried out via

the oil temperature probe. The engine temperature must not

be determined with engine running, otherwise the engine and

probe could be damaged!

– Bring engine to required temperature.

Measuring idling speed:

It is automatically switched to display for measuring the idling

speed.

– Follow instructions on display.

Measurement starts when the engine speed has reached the re‐

quired level.

Note

♦ Do not insert emission probe into exhaust tail pipe.

♦ Measurement can be skipped using → button, i.e. the exhaust

emissions test has failed.

♦ Measured values are reset using ← button, and the test can

be repeated.

– Maintain engine speed in required engine speed range.

The remaining time to perform measurement is displayed

-arrow-.

Measuring rev limit:

Lupo 1999 ➤ , Lupo 3L 1999 ➤

Maintenance - Edition 03.2018

It is automatically switched to display for measuring rev limit.

Measurement starts when the engine speed has reached the re‐

quired level.

– Operate throttle until the measurement is carried out. To do

this, immediately depress accelerator pedal.

The remaining time to perform measurement is displayed

-arrow-.

Note

♦ Do not insert emission probe into exhaust tail pipe.

♦ Measurement can be skipped using → button, i.e. the exhaust

emissions test has failed.

Air quality check:

An air quality check is carried out before starting the free accel‐

eration. When doing this, no emission probe must be in the

exhaust tail pipe. Otherwise measuring errors or faulty signals

could occur during further measurements.

– When the air quality check is carried out, insert emission probe

into exhaust tail pipe

Free acceleration:

It is automatically switched to display for “Free acceleration”.

During “Free acceleration” the engine is revved up to rev limit

without load as quickly as possible.

The “Free acceleration” test consists of at least four throttle

bursts.

Free acceleration - phase 1:

– Follow instructions on display -arrow A- and -arrow C-.

– Maintain idling speed in engine speed range indicated

-arrow D-.

The remaining time to perform measurement is displayed

-arrow B-.

Note

♦ The emissions probe must be in the exhaust tail pipe.

♦ If the speed deviates from engine speed range indicated, the

measurement starts again.

♦ Measurement can be skipped using → button, i.e. the exhaust

emissions test has failed.

Free acceleration - phase 2:

5. Exhaust emissions test

Lupo 1999 ➤ , Lupo 3L 1999 ➤

Maintenance - Edition 03.2018

– Follow instructions on display -arrow B-.

– Depress accelerator pedal fully when prompted and hold until

the prompt for idling is shown on display.

Free acceleration - phase 3:

– Remove foot from accelerator pedal as soon as the prompt for

idling is shown on display -arrow B-, and run engine at idling

speed.

The test results and information on the latest “Free acceleration”

are shown on display -arrow A-. If the measured values are not

OK, here you can obtain information why the “Free acceleration”

has failed.

Note

♦ If the field is coloured white the measured value is within tol‐

erance.

♦ If the field is coloured red the measured value is outside tol‐

erance.

♦ If the field is coloured yellow the measured value is outside

tolerance, but can be assessed by the operator.

Further throttle bursts:

– Follow instructions on display -arrow B-.

Now the next throttle burst follows, starting with phase 1 of “Free

acceleration”.

Many “Free accelerations” can be carried out until:

♦ Three “Free accelerations” have been completed in succes‐

sion and the range of acceleration is OK.

♦ All values are OK, with the exception of range of acceleration,

and the test is continued by pressing the → button -arrow C-.

(In this case, the operator assesses if the value is OK).

♦ The values are not OK and the measurement is terminated/

skipped by pressing the → button -arrow C-.

If the measured values are OK after three throttle bursts in suc‐

cession, i.e. all fields are coloured white, the exhaust emissions

test is completed.

Evaluation:

When the exhaust emissions test has been performed, the log is

shown on display.

The test result is displayed.

Now remarks concerning the exhaust emissions test can be en‐

tered -arrow A-. They will then be included in the test log.

– When the exhaust emissions test is classed as passed, select

-arrow B- “EET sticker issued” in drop-down menu and date.

– Then confirm with “Yes” -arrow C-.

The exhaust emissions test log is shown on display and can be

printed out as often as required in the menu “Print preview” using

“Print” button -arrow A-.
