2016 AUDI A6 check engine

(D Note
Never use a fast charger as a booster to start
the engine . This will serious ly damage sensi­
tive electronic components, such as control units, relays, radio, etc., as well as the battery
charger.
Battery replacement
The new battery must have the same specifica­
tions and dimensions as the original equipment
battery .
Intelligent energy management in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle
¢ page 192 . The intelli ­
gent energy management system w ill keep the
engine battery charged better than vehicles with­
out this system . To make sure the addit ional
e lectrica l energy is available once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu­
facture only (the same as those installed at the
time your veh icle was delivered). Specifications
are listed on the battery housing. Your author­
ized dealer must code the battery in the energy
management system to enable you to use the en­
ergy management functions correctly after re­
p lacing the battery .
The new battery must have the same capacity,
voltage (12-volts), amperage, construction and
plug sealing .
When installing the battery, make sure the igni­
tion and all electrical consumers are sw itched
off.
(D Note
Make sure the ventilation hose on the side of
the battery is connected, otherw ise fumes or
battery acid can leak out.
- Vehicles with the Start-Stop-System* are
equipped with a special cycle-proof AGM
battery . Install ing a different type of bat­
tery can cause prob lems in the vehicle elec­
trical system. When replacing the vehicle
battery, always install one with the same
specifications as the original battery.
Checking and Filling
{® For the sake of the environment
Because of the problem of proper disposal of
a battery, we recommend your authorized
Audi dealer change the battery for you. Bat­
teries contain sulfur ic acid and lead and must
always be disposed of properly in compliance
with all environmental regulations. Disposing
of veh icle batteries improperly is very danger­
ous to the environment .

Emergency situations
Emergency situations
General
This chapter is intended for trained emergency crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
CD Note
Vehicles with an automatic transmission can­
not be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine con be started by con­
necting it to the battery of another vehicle .
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
clamps which are distinctly marked :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in­
jury. Follow the instructions below for safe hand Ling of your vehicle's battery .
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A discharged battery can freeze at tempera­
tures just below 32 °F (0 °C). Before con­
necting a jumper cable, you must thaw the
264
frozen battery completely, otherwise it could explode .
- Do not allow battery acid to contact eyes or
skin. Flush any contacted area with water immediately.
- Improper use of a booster battery to start a
vehicle may cause an explosion.
- Vehicle batteries generate explosive gases.
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not try to jump start any vehicle with a
low acid level in the battery .
- The voltage of the booster battery must also
have a 12-volt rating. The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batteries of different voltage or substantial­
ly different "Ah" rating may cause an explo­
sion and personal injury .
- Never charge a frozen battery. Gas trapped in the ice may cause an explosion .
- Never charge or use a battery that has been
frozen . The battery case may have be weak­
ened .
- Use of batteries of different voltage or sub­ stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
~page 216.
CD Note
-Applying a higher voltage booster battery
will cause expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
(+) terminals are connected.
@ Tips
The discharged battery must be properly con-
nected to the vehicle's electrical system. .,.

.... N
0 CJ ' M I.Cl ......
When jump starting or charging the battery,
never connect the negative ground cable to
the battery negative post because the battery
manager system must be able to detect the
battery's state of charge . Always connect the
negative ground cable to the negat ive ground
post of the battery manager control unit .
Use of jumper cables
Make sure to connect the jumper cable clamps in
exactly the order described below!
Fig. 214 Engine compa rtment: connec tor s for ju mp start
cables and cha rger
@
Fig. 215 Jump start ing with the battery of another vehicle:
@ -booste r battery ,@ -discharged vehicle battery
The procedure described below for connecting
jumper cables is intended to provide a jump start
for your vehicle.
Vehicle with discharged battery:
.. Turn off lights and accessories, move lever of
automatic transmission to N (Neutral) or P
(Park) and set parking brake .
Connect POSITIVE(+) to POSITIVE(+) (red)
.,. Open the red cover on the positive terminal
~fig. 214 .
Emergency situations
1. Connect one end of the red positive cab le on
the
jump start bolt~ fig. 215 (D (bolt under
the red cover = "posit ive") of the veh icle to be
started @.
2. Connect the other end to the posit ive termi-
nal @of the booster battery @.
Connect NEGATIVE (-) to NEGATIVE (- )
(black)
3. Connect one end of the black negative cable
to the negative terminal @ of the booster
battery @.
4 . Connect the other end to the
jump start pin
@ (bolts with hex head bolt= "negat ive") of
the vehicle to be started @.
Starting the engine
.. Start the engine of the vehicle with the booster
battery @. Run the eng ine at a moderate
speed .
.,. Start engine w ith discharged vehicle battery @
in the usual manner.
.,. If the engine fails to start, do not keep the
starter cranking for longer than 10 seconds.
Wait for about 30 seconds and then try again .
.. With engine running, remove jumper cables
from both vehicles in the exact
reverse order .
.. Close the red cover on the positive terminal.
The battery is vented to the outside to prevent gases from entering the vehicle interior . Make
sure that the jumper clamps are well connected
with their metal parts in full contact with the
battery term inals .
A WARNING
To avoid ser ious personal injury and damage
to the vehicle, heed all warnings and instruc­
tions of the jumper cable manufacturer.
If in
doubt, call for road service.
- Jumpe r cables must be long enough so that
the vehicles do not touch .
- When connecting jumper cables, make su re
that they cannot get caug ht in any moving
parts in the engine compartment.
- Before you check anything in the engine
compa rtment, always read and heed all
WARNINGS

Towing with a tow truck
General hints
Your Audi requires special handling for towing.
The fo llow ing informa tion is to be used by com­
mercial tow truck operators who know how to op­
era te the ir equipmen t sa fe ly .
- Never tow your Audi. Towing will cause dam­
age to the engine and transmi ssion.
- Never wrap the safety chains or winch cables
around the brake l ines .
- To prevent unnecessary damage, your Audi
must be transported with a flat bed truck.
- To load the vehicle on to the flat bed , use the
towing loop found in the vehicle tools and at­
tach to the front or rear anchorage
