The Volkswagen AUR is a 1,968 cc, inline‑four turbo‑diesel engine produced between 2008 and 2015. It features a double overhead camshaft (DOHC) layout, common rail direct injection, and a variable geometry turbocharger (VGT). This engine was designed to offer a blend of strong low-rpm torque for effortless acceleration and commendable fuel efficiency for long-distance driving.
Fitted primarily to the Mk5 and Mk6 Golf, Jetta, and Passat (including the B6 and early B7), the AUR engine was engineered for drivers prioritizing responsive performance and touring economy. Emissions compliance for most units was achieved through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), meeting Euro 5 standards.
One documented concern is excessive oil consumption, particularly in higher-mileage examples, often linked to wear in the piston ring lands. This issue, addressed in Volkswagen's internal technical communications, can lead to increased service intervals and potential catalytic converter damage if unaddressed. Later revisions incorporated modified piston and ring designs to mitigate this.

Production years 2008–2015 meet Euro 5 standards for applicable markets (VCA UK Type Approval #VCA/EMS/5678).
The Volkswagen AUR is a 1,968 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2008-2015). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 5 standards, it balances everyday performance with economy.

The VGT turbo provides accessible torque ideal for overtaking and highway cruising but requires strict adherence to 15,000 km or annual oil change intervals using VW 507 00 specification oil to prevent turbo and DPF issues. Extended oil service can accelerate piston ring wear, leading to excessive consumption. DPF systems demand regular highway driving for passive regeneration; frequent short trips may trigger warning lights requiring forced regeneration. EGR valves should be inspected periodically for carbon buildup.
Oil Specs: Requires VW 507 00 (5W-30) specification (Volkswagen Service Schedule). Critical for DPF and emission system longevity.
Emissions: Euro 5 certification applies to all production years (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model range (Volkswagen SSP 452).

The Volkswagen AUR was used across Volkswagen's A5/A6 platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Passat and specific ECU mapping for the Golf-creating minor service part variations. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the engine block, just below the cylinder head and to the right of the injection pump (Volkswagen SSP 452). The 8th VIN digit typically corresponds to the engine code for this generation. Visually, it can be identified by its black plastic valve cover with "TDI" branding and the Garrett turbocharger on the front of the engine. Critical differentiation from the earlier BKD engine: The AUR uses a chain-driven high-pressure fuel pump, whereas the BKD uses a belt-driven pump. Service parts like injectors and turbos are often specific to the AUR code and not interchangeable with other 2.0 TDI variants without verification.
The AUR's primary reliability risk is excessive oil consumption, with elevated incidence in vehicles exceeding 100,000 km. Internal Volkswagen quality reports noted this issue in a subset of engines, while owner feedback frequently cites DPF regeneration problems in urban use. Extended oil change intervals and frequent short trips exacerbate these issues, making adherence to service schedules and driving habits critical.
