2008 AUDI TT ROADSTER ECU

What do I do now? -
----------------
•
-Screw the threaded end of the alignment pin from the
tool kit hand-tight into the now vacant bolt hole
=:> page 270, fig. 177.
- Then completely unscrew the other wheel bolts as
described above.
- Take off the wheel leaving the alignment pin in the bolt
hole.
Putting on the wheel
- Lift the spare wheel and carefully slide it over the align­
ment pin to guide it in place.
- Use the hexagonal socket in the screwdriver handle to
screw in and tighten all wheel bolts slightly.
- Unscrew the alignment pin and insert and tighten the
remaining wheel bolt slightly like the rest.
- Turn the jack handle counter -clockwise to lower the
vehicle until the jack is fully released.
- Use the wheel bolt wrench to tighten all wheel bolts
firmly =:> page 268. Tighten them crosswise, from one
bolt to the (approximately) opposite one, to keep the
wheel centered.
[ i J Tips
Never use the hexagonal socket in the handle of the screwdriver to
loosen or tighten the wheel bolts.
• Pull the reversible blade from the screwdriver before you use the
hexagonal socket in the handle to turn the wheel bolts.
• When mounting tires with
unidirectional tread design make sure
the tread pattern is pointed the right way~
page 272.
• The wheel bolts should be clean and easy to turn. Check for dirt
and corrosion on the mating surfaces of both the wheel and the
hub . Remove all dirt from these surfaces before remounting the
wheel. •
Notes on wheel change
Please read the information~ page 249, "New tires and replacing
tires and wheels", if you are going to use a spare tire which is
different from the tires on your vehicle.
After you change a tire:
• Check the tire pressure on the spare immediately after
mounting.
• Have the wheel bolt tightening torque checked with a torque
wrench as soon as possible by your authorized Audi dealer or a qualified service station .
• With steel and alloy wheel rims, the wheel bolts are correctly
tightened at a torque of 90 ft lb (120 Nml.
• If you notice while changing a tire that the wheel bolts are
corroded and difficult to turn, then they should be replaced before
you check the tightening torque.
• Replace the flat tire with a new one and have it installed on your
vehicle as soon as possible. Remount the wheel cover.
Until then, drive with extra care and at reduced speeds.
& WARNING
• If you are going to equip your vehicle with tires or rims which
differ from those which were factory installed, then be sure to read
the information
~ page 249, "New tires and replacing tires and
wheels".
• Always store the tools securely in luggage compartment.
Otherwise, in an accident or sudden maneuver they could fly
forward, causing injury to passengers in the vehicle.

ARNING (continued )
• Do not attempt any of the maintenance , checks or repairs
described on the following pages if you are not fully familiar with
these or other pro cedures with respect to the vehicle , or are uncer­
tain how to proceed.
• Do not do any work without the proper tools and equipment.
Have the necessary work done by your autho rized Audi dealer or
another properly equipped and qualified workshop .
• The engine compartment of any motor vehicle is a potentially
hazardous area . Never reach into the area around or touch the
radiator fan . It i s temperature controlled and can switch on
suddenly -even when the engine is off and the ignition key has
been removed . The radiator fan switche s on automatically when
the coolant reaches a certain tempe rature and will continue to run
until the coolant temperature drops .
• Always remove the ignition key before anyone gets under the
vehicle.
• Always support your vehicle with safety stands if it is neces­
sary to work underneath the vehicle. The jack supplied with the
vehicle is not adequate for this purpose and could collapse
causing serious personal injury .
• If you must work underneath the vehicle with the wheels on
the ground, always make sure the vehicle is on level ground , that
the wheels are always securely blocked and that the engine
cannot be started .
• Always make sure the transmission selector lever (automatic
transmission) is in "P" (Park position ) (automatic transmission ) or
Neutral (manual tr ansm ission) and the hand brake is firmly
applied.
• Chang ing t he e ngine sett ings wi ll a dverse ly affect em ission
levels. This is detrimenta l to the environment and increases fuel
co nsu mp tion.
