The Volkswagen PN is a 1,984 cc, inline‑four turbocharged petrol engine produced between 2006 and 2010. It features direct fuel injection (FSI), dual overhead camshafts (DOHC), and variable valve timing, delivering 147 kW (200 PS) and 280 Nm of torque. The FSI system enables precise fuel metering for improved efficiency and throttle response.
Fitted to models such as the Golf Mk5 R32 (limited applications), Passat B6, and Eos, the PN was engineered for sporty yet refined performance with strong mid-range pull and smooth high-rpm delivery. Emissions compliance was achieved through stratified lean-burn operation and a three-way catalytic converter, meeting Euro 4 standards across all markets.
One documented concern is high-pressure fuel pump (HPFP) failure due to insufficient lubrication from low-sulfur fuels, highlighted in Volkswagen Service Bulletin 2008‑07‑03. Early HPFP designs used inadequate cam-follower materials, leading to premature wear. From mid‑2008, revised pumps with hardened components were introduced.
Volkswagen
Production years 2006–2010 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5678).
The Volkswagen PN is a 1,984 cc inline‑four turbocharged petrol engine engineered for mid‑size sedans and coupes (2006–2010). It combines gasoline direct injection (FSI) with a single turbocharger to deliver responsive power and strong mid‑range torque. Designed to meet Euro 4 emissions standards, it balances sporty performance with acceptable fuel economy.

The FSI turbo system delivers crisp throttle response but demands high-quality RON 95+ fuel and strict 10,000 km oil changes to protect the high-pressure fuel pump and timing chain. VW 502 00/505 00 oil is essential due to its compatibility with the cam-driven HPFP. Extended idling or frequent short trips accelerate carbon buildup on intake valves (no port injection). Early HPFP units (pre-08/2008) should be proactively replaced per SIB 2008‑07‑03. Turbo wastegate rattle may develop after 120,000 km; K04 actuator recalibration is often required.
Oil Specs: Requires VW 502 00 or 505 00 (5W-40) specification (Volkswagen SIB 2008‑07‑03). Not compatible with Longlife-04.
Emissions: Euro 4 certification applies to all PN engines (2006–2010) (VCA Type Approval #VCA/EMS/5678). No Euro 5 variants exist.
Power Ratings: Measured under DIN 70020 standards. Output assumes RON 95 fuel (Volkswagen TIS Doc. 06K‑301).

The Volkswagen PN was used across Volkswagen's B6/1K platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced engine mounts in the Passat and modified exhaust routing in the Eos—and from 2008 the HPFP revision created service part splits, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the oil filler neck (Volkswagen TIS 06K‑001). The 4th and 5th VIN digits indicate engine family ('BP' for 2.0 TFSI series). PN engines feature a black plastic intake manifold with “2.0 TFSI” badge and K04 turbo with integrated diverter valve. Critical differentiation from CA/CD/CF engines: PN uses Bosch MED9.5.10 ECU with 120-bar FSI rail; later engines use MED17 with higher pressure. HPFP part number 06F 127 025 A/B indicates pre-revision; C/D/E denotes updated units per SIB 2008‑07‑03.
The PN's primary reliability risk is high-pressure fuel pump (HPFP) failure on early builds, with elevated incidence in vehicles using low-quality fuel or extended oil intervals. Volkswagen internal data from 2009 indicated a significant number of pre-2008 engines required HPFP replacement before 80,000 km, while UK DVSA records show elevated fuel system-related MOT advisories in high-mileage examples. Short-trip driving and infrequent oil changes accelerate wear, making fuel quality and maintenance critical.
