The 1.8-liter turbo engine Volkswagen AUQ 1.8T was assembled at the factory from 2001 to 2006 and was installed on models with a transverse engine: Golf 4, Bora, Octavia and Audi A3. This power unit was slightly more powerful than its counterparts in the series, developing 180 hp and 235 Nm.
The most powerful transverse 1.8T versions were built for the first-generation Audi S3 (8L): the APY, AUL and AMK produced 210 PS and 270 Nm, and the BAM, introduced in 2001, 225 PS and 280 Nm. The 225 PS version (APX, BAM) was also used in the Audi TT and the SEAT León Cupra R. These engines differ from the AUQ in a larger K04 turbocharger and strengthened internals.
EA113-1.8T family: AGU, AWT, AMB, AWM, AUQ, AWC.

Disadvantages of the VW AUQ engine
- The main reason for the unstable operation of the engine is the constant air leakage through the crankcase ventilation;
- Numerous branch pipes of the crankcase ventilation system simply crack;
- A low resource has a hydraulic chain tensioner, which plays the role of a phase regulator here;
- Often there are leaks of antifreeze from the tee of the cooling system and failures of the coolant temperature sensor;
- Ignition coils with built-in switches fail very quickly.
