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)…

Production years 2008–2015 meet Euro 5 standards for applicable markets .
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 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.
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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The AUR offers strong performance and efficiency, but its long-term reliability is often linked to the known oil consumption issue. Well-maintained examples that have had the piston/ring update or show minimal consumption can be very dependable. Strict adherence to oil change intervals using VW 507 00 oil is paramount for longevity.
The most frequent issues are excessive oil consumption, DPF regeneration failures (especially with city driving), clogged EGR valves, and failing turbocharger actuators. These are well-documented in Volkswagen's service information and owner communities.
The AUR 2.0 TDI was used in the Volkswagen Golf Mk5 (2008-2009) and Mk6 (2009-2013), Jetta Mk5 (2008-2010), and Passat B6 (2008-2010) and B7 (2010-2015). It was a common engine for these models during the late 2000s and early 2010s.
Aftermarket ECU tuning is common on the AUR platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Excellent for its era. In a Golf or Jetta, expect real-world figures of around 5.5-6.0 L/100km (47-51 mpg UK) combined. The heavier Passat will return slightly less, typically 6.0-6.5 L/100km (43-47 mpg UK) on mixed driving, depending on conditions and driving style.
Yes. Like virtually all modern engines, the AUR is an interference design. If the timing chain fails or jumps, the pistons will collide with the open valves, causing catastrophic engine damage. Fortunately, the timing chain is generally very durable on this engine.
Volkswagen mandates the use of oil meeting the VW 507 00 specification, typically a 5W-30 synthetic. This low-ash oil is critical for protecting the DPF and emission control systems. Using the wrong oil can lead to premature DPF clogging and expensive repairs.
