"To increase the power output and torque of
the 1.8-ltr. 5V engine to 165 kW, it was neces-
sary to make various design modifications to
the basic engine of the Audi TT Coupé
developing 132 kW.
A characteristic feature of the engine is its
higher air demand, making it necessary to
enlarge the diameter of the intake port and
exhaust gas turbocharger.
Since the previous charge air cooler was no
longer capable of effectively cooling down the
increased air flow through the exhaust gas
turbocharger, it was necessary to accommo-
date a second, parallel charge air cooler on
the left-hand side of the vehicle.
The secondary air system in the 1.8-ltr. 5V
engine developing 165 kW ensures that the
exhaust emissions comply with the EU III+D3
standard.
A probe will be installed downstream of the
catalytic converter to meet the requirements
stipulated in EU III."
De APX heeft trouwens ook een andere versnellingsbak dan de AJQ. In je serviceboekje kun je zien met welke motor en bak je auto uit de fabriek is gekomen. Wat op de motor staat is normaal gesproken wel wat het is...
