Audi Q5: General Information
Vehicles with a high-voltage system (hybrid vehicles)
Extremely Dangerous Due to High-Voltage
The high-voltage system is under high-voltage. Death or serious
bodily injury by electric shock.
- Individuals with electronic/medical life- and health sustaining
machines in or on their person cannot perform any work on high-voltage
systems. Life- and health sustaining machines are for example pain
killer pumps, implanted defibrillators, pacemakers, insulin pumps, and
hearing aids.
- Have the high-voltage system de-energized by a qualified person.
There is a Risk of Injury from the Engine Starting Unexpectedly
On electric - hybrid vehicles an active ready mode is difficult to
identify. Parts of the body can be clamped or pulled.
- Turn off the ignition.
- Place the ignition key outside of the vehicle interior.
Risk of Damaging the High-Voltage Cables
Misuse can damage the insulation of high-voltage cables or
high-voltage connectors.
- Never support objects on the high-voltage cables and the
high-voltage connectors.
- Never support tools on the high-voltage cables and the high-voltage
connectors.
- Never sharply bend or kink the high-voltage cables.
- When connecting pay attention to the coding of the high-voltage
connectors.
- For all procedures on vehicles with high-voltage system pay
attention to the additional warning message for these vehicles.
Refer to
→ Chapter "Warnings when Working on Vehicles with High Voltage
System".
- If procedures are necessary near components of the
high-voltage system "perform a visual inspection of the damage
of the high-voltage components and lines". Refer to
→ Chapter "Performing a Visual Inspection of Damage to High
Voltage Components and Cables".
- If work on the components of the high-voltage system is
necessity, de-energize the high-voltage system. Refer to
→ Rep. Gr.93; High-Voltage System, De-Energizing or
→ Electrical Equipment; Rep. Gr.93; High-Voltage System,
De-Energizing.
- Charge the vehicle battery, for example, using the Battery
Charger -VAS5904- in the battery support mode to minimize the
number of automatic starts during the test- and measuring
procedures while the ready mode is active. Refer to
→ Electrical Equipment General Information; Rep. Gr.27; Battery;
Charging the Battery and
→ Electrical Equipment; Rep. Gr.93; General Notes for Working on
the High Voltage System.
- Move the selector level into position "P", activate the
parking brake and arrange the necessary tools for testing and
measuring procedures that require the ready mode to be active or
that require the ignition to be on, so that they cannot come
into contact with the turning components in the engine and so
that they are not in the vicinity of the turning components of a
running engine.
Note
- Also move the selector lever into position "P" and activate
the parking brake for testing and measuring procedures which
require the ignition to be on, but do not require the ready mode
to be active.
- The ready mode is displayed in the Instrument Cluster
Control Module -J285- above the "powermeter". Refer to Owner's
Manual.
- Activate and deactivate the ready mode. Refer to Owner's
Manual (consult the display in the Instrument Cluster Control
Module -J285-).
Vehicles with Start/Stop System
There is a Risk of Injury from the Engine Starting Unexpectedly
The engine can start unexpectedly on vehicles with an activated
Start/Stop System. A message appears in the instrument cluster
indicating whether the Start/Stop System is activated.
- Deactivate the Start/Stop System: Turn off the ignition.
All Vehicles
Caution
- If it is suspected that chemicals were added to the
refrigerant circuit to seal leaks, chemical substances
to seal leaks in the refrigerant circuit (leak stop
additive), do not connect the A/C service station and do
not extract the refrigerant.
- Chemicals that seal leaks in the coolant circuit
form deposits that affect the function of the A/C system
and lead to failure of the A/C system and the A/C
service station.
- Inform that customer that there are substances in
the A/C system that are no approved by Audi.
Note
- The chemical materials (stop leak additive) for sealing
leaks in the refrigerant circuit offered on the market are not
approved by Audi AG. There are no permanent- ,validity or
material compatibility tests. Therefore, damage or malfunctions
in the A/C system or the A/C Service Station cannot be excluded.
- The stop leak additives offered on the open market have
different physical and chemical properties, which can impair the
function of the A/C system and the A/C Service Station and can
even shut down the system completely.
- Audi does not approve the use of chemicals to seal leaks in
the refrigerant circuit (leak stop additives).
- Chemical materials (leak stop additives) to seal leaks in
the refrigerant circuit react with air or the moisture in the
air and form deposits in the refrigerant circuit (and in the A/C
service station) that lead to malfunctions in the valves and
other components that come into contact with such chemicals.
These deposits cannot be removed completely from the components
(also not through cleaning/flushing with refrigerant R134a).
- It is not possible to recognize chemical substances to seal
leaks in the refrigerant circuit (leak stop additive) and the
label that is supposed to come with them is usually not there.
Therefore be careful when working with if you do not know its
service history.
- Accessories offer containers used to separate out these
chemicals (used to seal leaks in the refrigerant circuit). Since
Audi does not know composition and the physical and chemical
properties of these materials, it is not possible to make a
statement about their effectiveness and the deposition rate of
these filters.
- The Filter for Sealants -VAS6592- offers a certain
protection for the A/C service station. This filter is
incorporated between the A/C service station and the Service
connection on the low pressure side of the refrigerant circuit
in a vehicle (the A/C service station may not be connection to
the service connection of the high pressure side of the
refrigerant circuit for draining, evacuating and measuring).
This filter separate certain materials that were added to seal
leaks in the refrigerant circuit. It prevents these materials
from getting into the refrigerant and refrigerant oil in the A/C
service station unchecked and doing damage. For the protection
to work, it is necessary that the filter be changed in regular
intervals and exactly according to the manufacturer
specifications (described in the instructions provided). Audi
does not support using chemical materials (stop leak additives)
for sealing leaks in the refrigerant circuit. There are many
different formulas of these chemicals (stop leak additives),
that are offered as "sealant for refrigerant circuits" and it is
not possible to make a statement about the effectiveness of the
Filter for Sealants -VAS6592-.
If the refrigerant circuit gets filed with a chemical
material (stop leak additive) to seal any leaks (or if there is
a suspicion of this) and if it then necessary to perform a
repair to the refrigerant circuit, then it is necessary to
inform the customer of the following:
- It is not possible to evacuate the refrigerant from the A/C
system due to the stop leak additive that has been added to the
system because it will damage the A/C Service Station. It will
necessary to hire an outside company the can evacuate the
contaminated refrigerant with a suitable device and then dispose
of it (for example, a local waste management company that
specializes in disposing of refrigerant).
- It will be necessary to replace any refrigerant circuit
components that have come in contact with the stop leak additive
in order to repair the A/C system properly. Certain refrigerant
circuit components may already be damaged by the stop leak
additive (for example, the A/C Compressor Regulator Valve
-N280-) or will get damaged if they are used over again and will
fail after a short amount of time. In addition to this, if there
is any sediment from the stop leak additive still in the
circuit, it could come loose at a later point and cause the A/C
system to fail again (currently it is not possible to clean
these components with any workshop tools).
