Engine oil consumption 
The  engine  in your  vehicle depends  on an ade
quate  amount  of oil to lubricate  and  cool all of  
its  moving  ports. 
In order  to  prov ide  effect ive  lub ricat ion and  cool 
ing of internal  engine  components,  all internal  
combustion  engines  consume  a certain  amount  
of oil. Oil consumption  var ies from  engine  to  en
gine and  may change  significantly  over the  life of 
the  engine.  Typically, engines  w ith  a specified 
break-in  period 
(see<=> page  80)  consume  more 
o il dur ing the  break-in  per iod than  they  consume 
after  o il consumption  has  stabi lized . 
U nder  normal  cond itions,  the  rate  of oil con
sumption  depends  on the  quality  and viscos ity of 
the  oil, the  RPM (revolutions  per  m inute)  at 
wh ich the  engine  is operated,  the  amb ient  tem
perature  and  road  condit ions.  Furthe r facto rs a re 
t h e amo unt  of o il di lution  from  wate r condensa
t ion or fue l residue  a nd the  oxidat ion level of  the 
oi l. As any engine  is subject  to  wear  as  mileage 
builds  up, the  oi l consumption  may increase  ove r 
ti me  until  replacement  of worn  components  may 
become  necessary. 
With  a ll these  variab les  coming  into  p lay, no 
standard  rate  of oil cons umption  can be estab 
li shed  or specified . There  is no alternative  to  reg
ular and  frequent  checking of the  oil level, see 
Note . 
If the  yellow engine  oil leve l warning  symbo l El 
in the  instrument  cluster  lights  up, you should 
check the  o il level as  soon  as  possible 
<=> page  32  7. Top off the  o il at your earliest  con
venience

(D Note 
Driving with  an  insufficient  oil  level is  likely to 
cause  severe  damage  to  the  engine. 
@ Tips 
-The oil  pressure  warning  display.  is  not  
an indicator  of the  oil  level.  Do not  rely on 
it.  Instead,  check  the  oil  level  in your en
gine  at  regular  intervals,  preferably  each  
time  you  refuel,  and  always  before  going  
on  a long  trip. 
-If  you  have the  impression  your  engine  con
sumes  excessive  amounts  of  oil, we recom
mend  that  you  consult  an  authorized  Audi 
dealer  to have  the  cause  of  your  concern 
properly  diagnosed.  Keep  in  mind that the 
accurate  measurement  of  oil consumption 
requires  great care  and  may take  some 
time.  An authorized  Audi  dealer  has instruc
tions  about  how to  measure  oil consump 
tion  accurately. 
Checking the  engine  oil  level and  adding  
engine  oil 
The engine  oil level can be checked in the Info 
tainment  system

- Close  the  engine  oil filler  opening  cap. 
- Close  the  hood,  restart  the  ignition  after  two 
minutes  and  read  the current  oil  level  in the  In 
fotainment  system. 
A WARNING ...__ --When  adding  oil,  do not  let  oil drip  onto  hot 
engine  components.  This increases  the  risk 
of  afire. 
-You must  secure  the cap  on  the  oil filler 
opening  correctly  so  that  oil does  not  leak 
out  onto  the hot  engine  and exhaust  system 
when  the engine  is  running,  because  this  is 
a fire  hazard. 
-Always  clean  skin  thoroughly  if it  comes  into 
contact  with  engine  oil. 
0 Note 
- The  engine  oil  level  must  not be under  the 
"min" marking,  because  this  increases  the 
risk  of  engine  damage. 
- If the  message II Please  reduce  oil level 
appears,  there  is too  much  oil in the  engine 
and  there  is a risk  of  damaging  the  catalytic 
converter  and  engine.  Do not  start  the  en 
gine.  Contact  an  authorized  Audi dealer  or 
authorized  Audi Service  Facility  to  have  ex
cess  engine  oil extracted  if necessary. 
- Do not  mix  any  additional  lubricants  into 
the  engine  oil.  Damage  caused  by such  addi-
tives  is not  covered  by the  warranty.

mend  occasiona lly  checking  the  coolant  level 
manually. 
If you  must  add  coolant,  use  a  mixture  of  water 
and  coolant  addit ive.  Mixing  the  coolant  additive 
with  distilled  water is recommended. 
Coolant  additive 
The coolant  additive  is made  of  anti -freezing  and 
corrosion  protection  agents.  Only  use  the  fol low
ing  coolant  additives . These  additives  may  be 
mixed  with  each  other.
