– 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 when 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 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-.

– Press button “Close” -arrow B- to close the menu “Print pre‐

view ”.

– Follow instructions on display.
– Take emission probe out of exhaust tail pipe.

– Then press 

 button -arrow B-.

The exhaust emissions test is completed, a new exhaust emis‐

sions test can be performed.

are not necessarily generally valid!

Term

Explanation

ABS

Anti-lock brake system: the ABS is a regulating system in the brake system, that pre‐

vents locking when braking. This helps to maintain directional stability and steerability.

ATF

Automatic transmission fluid: gear oil for automatic gearboxes.

ATF level

Filling level of ATF in gearbox

CO

Carbon monoxide is produced when fuels containing carbon are not combusted com‐

pletely.

CN

Cetane number: measurement unit for ignition quality of diesel fuel

DIN

Deutsches Institut für Normung e.V (German institute for standardization)

E85

Liquid ethanol fuel for use of adapted petrol engines (ratio: 85 % ethanol to 15 % petrol)

Part No.

Abbreviation for part number

EN

European standard

EOBD

European onboard diagnosis

FAME

Fatty acid methyl ester

FSI

Fuel Stratified Injection: fuel stratified injection

TFSI

Turbo fuel stratified injection

TSI

From model year 2008 the designation TFSI is replaced by TSI. Therefore the desig‐

nation TSI is given to TSI turbocharger and TSI twincharger.
TSI turbocharger: charging only with turbocharger
TSI twincharger: charging with turbocharger and compressor

MIL

Malfunction Indicator Light: American designation for exhaust emissions warning lamp

K83

NAR

North American Region

OBD

Onboard diagnosis: the OBD monitors all components influencing the exhaust emis‐

sions quality

OBD-II

American onboard diagnosis

PD

Unit injector: injector for diesel engines

PR No.

Abbreviation for production control number. It identifies among other things optional

equipment or country-specific deviations

PM

Particulate matter: soot particulate value for diesel engine emissions

QG0

Vehicles “not” factory-fitted with components for LongLife service. For maintenance the

time and distance dependent intervals (non-flexible intervals) are valid.

QG1

Vehicles are factory-fitted with active LongLife service. This means, vehicles have a

flexible service interval display and are fitted with the following components:

♦ Flexible service interval display in dash panel insert
♦ Engine oil level sensor
♦ Brake pad wear indicator

QG2

The LongLife service is not factory-activated. This means, vehicles have a non-flexible

service interval display (time and distance dependent service intervals) and are fitted

with the following components:

♦ Non-flexible service interval display in dash panel insert
♦ Engine oil level sensor
♦ Brake pad wear indicator

Readiness code

8-digit binary code which indicates if all exhaust relevant diagnoses have been per‐

formed by the engine management.

RON

Research octane number: measurement unit of the knock resistance of petrol

SAE

Society of automotive engineers: association which creates proposals and guidelines

for implementing legal requirements (e.g. standards)

SD

Naturally aspirated diesel engine

SDI

Naturally aspirated diesel engine - direct injection

TDI

Turbo diesel engine - direct injection

DP

ULEV

Ultra-low emission vehicle

ESI

Extended servicing intervals

Common rail

English term, refers to a common high-pressure injection line (rail), which supplies all

cylinders of the relevant cylinder bank with fuel.

Diesel particulate

filter

The diesel particulate filter is installed behind the catalytic converter and filters soot

particles from emissions.

LongLife service

The long-life service enables extremely long inspection or oil change intervals, depend‐

ing on individual driving style and conditions under which the vehicle is used. For the

LongLife service a special engine oil is required.

Step-type probe

It is also called finger probe, LPH (lambda probe heating), FLP (flat lambda probe) or

planar lambda probe. The voltage of the output signal of the lambda probe jumps rapidly.

The lambda probe value is determined by a change in voltage. The probe is used as

after catalytic converter probe.

Broad-band probe Also called ULP (universal lambda probe). The voltage of the lambda probe output

nearly increases linear. The lambda probe value is determined by a change in voltage.

This enables to measure the lambda probe value via a larger measuring range (broad

band). The probe is used as before catalytic converter probe.
