The Volkswagen DA is a 1,588 cc, inline‑four naturally aspirated petrol engine produced between 1975 and 1983. It features a cast‑iron block and head, single overhead camshaft (SOHC), and 8 valves. In standard form it delivered 55 kW (75 PS) at 5,200 rpm and 123 Nm of torque at 3,000 rpm, providing dependable performance for compact VW models of the era.
Fitted to models such as the Golf Mk1, Jetta Mk1, and Scirocco Mk1, the DA was engineered for economical daily driving with st…
Production years 1975–1983 meet national type approval standards predating Euro 1 .
The Volkswagen DA is a 1,588 cc inline‑four naturally aspirated petrol engine engineered for compact models (1975–1983). It combines SOHC 8‑valve architecture with carburetted fuel delivery to deliver reliable, economical performance. Designed before harmonised EU emissions standards, it complies with national type approvals of the period.

The Volkswagen DA was used across Volkswagen's Golf Mk1/Jetta Mk1/Scirocco Mk1 platforms with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Jetta and modified air cleaner assemblies in the Scirocco—and from 1980 the distributor drive gear material was upgraded, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The DA is mechanically simple and robust when maintained properly, but early models (1975–1979) are prone to distributor drive gear wear. Later revisions improved durability. Critical maintenance includes periodic carburettor servicing and using minimum 91 RON fuel. With these observed, the engine can exceed 200,000 km reliably.
Top issues are distributor drive gear wear (causing timing drift), carburettor imbalance or flooding, timing chain stretch, and head gasket failure. These are documented in Volkswagen service bulletins 01‑78‑04 and standard maintenance advisories.
The DA powered the Golf Mk1 L/GL (1975–1983), Jetta Mk1 L/GL (1979–1983), and Scirocco Mk1 L/GL (1975–1981). It was exclusive to Volkswagen and not shared with Audi, SEAT, or Škoda during this period.
Yes. The DA responds well to mild tuning: performance camshaft, twin-choke carburettor upgrade, and exhaust manifold can yield +10–15 kW. Stock internals are reliable up to ~90 PS, but avoid aggressive modifications without head work.
In a Golf Mk1, expect ~9.8 L/100km (city) and ~6.5 L/100km (highway), or about 29–43 mpg UK combined. Real-world mixed driving typically returns 32–38 mpg UK, depending on condition and driving style.
No. The DA is a non-interference engine. If the timing chain fails, pistons will not contact open valves, preventing catastrophic internal damage. However, ignition and valve timing will be lost, requiring repair before restart.
Volkswagen originally specified SAE 10W‑40 mineral oil meeting API SF/CC. Modern semi-synthetic 10W‑40 oils meeting ACEA A3/B3 are acceptable, especially with lead replacement additives if running on unleaded fuel to protect valve seats.
