VW A4 A3 1.8T AEB APT

The VW A4 A3 1.8T AEB APT is built around the AEB, a 1.8L Inline-4 petrol engine with a DOHC, 20-valve cylinder head and turbocharged. Well-known 20-valve 1.8T used widely across the VW/Audi range. This unit is supplied by Tovesageneral Motors as a tested, ready-to-fit replacement for workshops and owners who need genuine factory characteristics rather than a generic substitute, and every engine is pulled from a running donor vehicle rather than sourced blind from an unknown history. Choosing a like-for-like AEB over a cheaper mismatched substitute avoids the wiring, mounting and ECU-calibration headaches that come with swapping in a different engine family.

Key Specifications: Configuration - Inline-4, 1.8L displacement. Valvetrain - DOHC, 20-valve. Fuel System - Petrol injection. Aspiration - Turbocharged. Power Output - approximately 150 hp (112 kW). Torque - 210 Nm. These figures reflect the factory-rated output for the AEB in its most common calibration; individual market tunes, transmission pairing and emissions equipment can shift the exact number slightly from one production year to the next, so always cross-check against the specific model year of your vehicle.

Performance Highlights: Well-known 20-valve 1.8T used widely across the VW/Audi range. Buyers should expect the driving character typical of a turbocharged petrol inline-4: strong mid-range pull with the power delivery concentrated once boost builds, and a noticeably flatter torque curve than a comparable non-turbo unit. As with any used engine, a full service history and a compression/leak-down check are recommended before installation, along with inspection of the timing components, seals, mounts and ancillaries such as the alternator, water pump and turbocharger (where fitted) prior to fitment.

Common Applications: The AEB was factory-fitted to VW Passat/Golf, Audi A4. If you are sourcing this engine for a different chassis, confirm the exact engine code stamped on the block and the wiring/ECU variant before ordering, since several body styles shared this family across multiple model years and markets. Our team can help verify fitment against your VIN before dispatch so the engine you receive matches your loom, mounts and transmission bellhousing pattern.
