Term Explanation
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
QG3 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
♦ 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)
SCR With the SCR process (selective catalytic reduction) the noxious nitrogen oxides emis‐
sions are reduced to a great extent and are converted to steam and nitrogen by the urea
solution.
A special urea solution (AdBlue®) is injected into the exhaust system upstream of a
special catalytic converter.
SD Naturally aspirated diesel engine
SDI Naturally aspirated diesel engine - direct injection
TDI Turbo diesel engine - direct injection
DP Distributor injection pump
ULEV Ultra-low emission vehicle
ESI Extended service interval
Common rail Refers to a common high-pressure injection line (rail), which supplies all cylinders of the
relevant cylinder bank with fuel.
LongLife service The LongLife service enables extremely long inspection or oil change intervals, de‐
pending 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 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 probe) universal lambda probe. The voltage of the output of the lambda
probe 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.
RDK, RKA Tyre pressure monitoring, tyre monitor display
Additive This fluid enables to attain the ignition temperature required to burn soot particles in
diesel particulate filters, which are installed at some distance from the engine.
Ash mass Is the mass which remains in the filter as waste product, when soot particles are burnt
or by regeneration of the diesel particulate filter. The permissible ash mass must be read
with diagnostic tester and is the criteria for changing the DPF.
