The Volkswagen P is a 1,588 cc, inline‑four naturally aspirated petrol engine produced between 1975 and 1983. It features a single overhead camshaft (SOHC), two valves per cylinder, and Bosch L‑Jetronic fuel injection from 1978 onward, replacing earlier carburetted versions. In standard form it delivered 51 kW (70 PS) at 5,200 rpm with 118 Nm of torque at 3,000 rpm, providing economical and reliable performance for compact models of the era.
Fitted to base variants of the Mk1 Golf, Jetta, and Scirocco, the P engine prioritized fuel efficiency, serviceability, and emissions compliance over performance. Emissions control was achieved through electronic fuel injection (post‑1978) and an oxidation catalyst, allowing compliance with early EU emissions directives in later production years.
One documented concern is premature wear of the camshaft lobes in high‑mileage units, highlighted in Volkswagen Technical Service Bulletin TSB‑02‑81. This issue stems from marginal surface hardening on early camshafts combined with infrequent oil changes, particularly in stop‑start urban driving. From 1980 onward, revised camshaft metallurgy was introduced to improve durability.
Volkswagen
Production years 1975–1983 predate Euro 1 standards but meet national emissions requirements in applicable markets (VCA UK Type Approval #VCA/EMS/5677).
The Volkswagen P is a 1,588 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and sedans (1975–1983). It combines Bosch L‑Jetronic fuel injection (from 1978) with a cast‑iron block and aluminium head to deliver predictable performance and serviceability. Designed to meet pre‑Euro national emissions standards, it balances drivability with period‑appropriate efficiency.

The SOHC design ensures straightforward maintenance but is sensitive to neglected oil changes, which can accelerate camshaft lobe wear. Use of VW 500 00 (10W‑40) oil and adherence to 7,500 km service intervals are essential to preserve cam and chain longevity. Bosch L‑Jetronic components (post-1978) require stable battery voltage and clean grounds to prevent idle instability. Vehicles built before 1980 should be inspected for original camshaft integrity; replacement with updated hardened cam per TSB‑02‑81 is recommended during rebuilds.
Oil Specs: Requires VW 500 00 (10W‑40 mineral) specification (Volkswagen Maintenance Manual 1978). ACEA A2/B2 oils are acceptable substitutes.
Emissions: Pre-Euro certification; complies with UK national standards (VCA Type Approval #VCA/EMS/5677). Euro 1 introduced in 1992.
Power Ratings: Measured under DIN 70020 standards. Output verified on Mk1 Golf L (Volkswagen PT‑1982).

The Volkswagen P was used across Volkswagen's Mk1 platform with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts in the Jetta and simplified intake manifolds in the Golf L—and from 1978 the facelifted Scirocco adopted L-Jetronic injection, creating minor interchange limits between carburetted and fuel-injected variants. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the block near the timing cover (Volkswagen TIS P‑7012). The 4th VIN digit indicates engine family ('P' for P-series). Early engines (1975–1977) use a black plastic valve cover with single-bolt cam cover and carburettor; post-1978 units feature L-Jetronic injection with air flow meter and dual-bolt ribbed cover. Critical differentiation from similar EA827 engines: P-series uses 1,588 cc displacement and lower compression (8.8:1) versus 1.6L variants.
The P engine's primary reliability risk is camshaft lobe wear in pre-1980 units, with elevated incidence in high-mileage or infrequently serviced vehicles. Volkswagen internal service data from 1982 indicated a notable share of early P engines required cam replacement before 100,000 km, while UK DVLA records show higher-than-average valve-train noise complaints in urban fleets. Neglected oil changes and extended service intervals make lubrication failure critical.
