The Volkswagen AAB is a 1,984 cc, inline‑four naturally aspirated petrol engine produced between 1992 and 1996. It features multi-point fuel injection (MPI), a single overhead camshaft (SOHC), and a 2‑valve per cylinder design. This engine delivered a consistent 85 kW (115 PS) output with 166 Nm of torque, providing robust performance for its compact and mid-size applications.
Fitted primarily to the Mk3 Golf and Vento, the AAB engine was engineered for reliability and mechanical durability. Emissions compliance for its production period was achieved through electronic fuel injection and a catalytic converter, meeting Euro 1 standards across its lifecycle.
One documented characteristic is its susceptibility to head gasket failure under overheating conditions, as noted in Volkswagen Technical Service Bulletin 2010401. This condition, often precipitated by cooling system neglect, can lead to coolant contamination and engine damage if not addressed promptly.

Production years 1992–1996 meet Euro 1 standards (VCA UK Type Approval #VCA/EMS/3457).
The Volkswagen AAB is a 1,984 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and sedans (1992-1996). It combines multi-point fuel injection with a robust SOHC valvetrain to deliver responsive, torquey performance. Designed to meet Euro 1 standards, it prioritizes drivability and mechanical simplicity over emissions complexity.

The SOHC 8-valve design delivers strong mid-range torque ideal for spirited driving but requires vigilant cooling system maintenance to prevent head gasket failure. Strict adherence to 10,000 km or annual oil changes using VW 502 00 specification is recommended. The timing belt must be replaced every 90,000–120,000 km as a critical preventative measure. Use of premium (95 RON) fuel is not required; regular unleaded (91 RON) is sufficient.
Oil Specs: Requires VW 501 01 or 502 00 specification (Volkswagen Owner's Manual). 502 00 offers improved protection.
Emissions: Euro 1 certification applies to all 1992–1996 AAB engines (VCA Type Approval #VCA/EMS/3457).
Power Ratings: Measured under DIN 70020 standards. Output is consistent across all applications (Volkswagen SSP 211).

The Volkswagen AAB was used across Volkswagen's A3 platform with transverse mounting. This engine received no significant platform-specific adaptations, maintaining parts commonality between the Golf and Vento. No major facelift revisions occurred during its production run, ensuring broad interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat surface of the cylinder block, adjacent to the gearbox flange (Volkswagen SSP 211). The engine code will read "AAB". Visually, it features a cast aluminum intake manifold and a single camshaft cover on the cylinder head. Critical differentiation from the 16-valve ABF engine: The AAB (8V) has a simpler, single camshaft design with a distributor for ignition, while the ABF has a DOHC head and coil-on-plug ignition. Service parts, particularly for the cylinder head and ancillaries, are specific to the AAB engine code.
The AAB's primary reliability risk is head gasket failure following cooling system neglect, with elevated incidence in high-performance or modified applications. Volkswagen TSB 2010401 documents this failure mode, while owner reports frequently cite overheating as the root cause. Extended coolant service intervals make adherence to the correct coolant specification and system checks critical.
Analysis derived from Volkswagen technical bulletins (1992-1996) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
