From 1996 until 2005, the company produced the 1.8-liter Volkswagen AGU 1.8T engine, which was fitted on well-known models like the Audi A3, the first Octavia, and the fourth Golf. Both the longitudinal AEB and this transverse power unit feature a cylinder head with large channels.
AGU, AWT, AMB, AWM, AUQ, and AWC are all part of the EA113-1.8T series.

Disadvantages of the VW AGU engine
A clogged catalyst can cause an engine turbocharger to fail very quickly;
Numerous issues arise from the crankcase ventilation system, particularly its frequently cracked pipes;
The engine speed is continuously floating because of air leaks in the intake manifold;
Here, the timing chain tensioner and oil pump have very few resources;
A malfunctioning mass air flow sensor or coolant temperature sensor is frequently the source of unstable engine operation.
