This engine is installed in large numbers in var-
ious Audi and VW models. Critical mistakes are
often made when changing the timing belt.
To ensure that changing the belt goes smooth-
ly, the ContiTech Power Transmission Group is
providing itters with detailed installation tips.
ContiTech experts explain step-by-step how
to change belts correctly. Audi recommends
changing the timing belt every 120,000 km and
itting a new tensioning pulley at the same time.
