Servotronic® - advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort .
The advanced Servotronic® power steering system senses the road
speed and ele ct ronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
veh icle speed .
Power steering will not work if the engine is off . As a resu lt, the
steeri ng wheel will be hard to turn.
T he power steeri ng fluid level is checked du ring the sched uled main ­
tenance services .
0 Note
If there is an electronic malfunction, servotronic will still function
like a conventional power s teer ing system, provid ing a cons tant
steering support force that is no longer proportionate to the vehicle
speed. This is most noticeable when t urning the s teer ing wheel at low
speeds (for example when park ing) , - more effor t will be required
than us ua l.
• Be aware of the d ifferent than usual steering response and adjust
your stee ring force accord ingly .
• Have the prob lem checked and set r ight by an Audi dealer as soon
as possib le.
[ i ] Tips
• When the e ngine is running, neve r hold the stee ring whee l turned
all the way to the rig ht or to the left for longer than 15 seconds. The
powe r steering pump wi ll overheat the hydra ulic fluid if yo u keep
holding the steering wheel turned all the way . This is likely to damage
t he power s teer ing system . •
If the power steering system s hou ld fa il entirely, or if the engine
is no t ru nning (fo r examp le, while be ing towed), you will st ill be able
to steer the vehicle. However,
considerably more effort will be
req uired to do so .
• If the power steering system should have a leak, or is not func­
tioning prope rly, con tact your au thor ized A udi dealer immedia tely.
• The power steer ing system requires a specia lly formulated
hyd raulic fluid. The power steer ing rese rvoir is the one loc ated
farthest to the rear on the left s ide of the eng ine compartme nt
