The Audi ANK is a 1,984 cc, inline — four petrol engine produced between 2008 and 2012. It features naturally aspirated design, double overhead camshafts (DOHC), and FSI direct fuel injection, delivering 125 kW (170 PS) at 6,000 rpm and 225 Nm of torque at 3,200 rpm. FSI technology enables precise fuel delivery for improved combustion efficiency and performance.
Fitted to models such as the 8P A3, 8E A4, and 3B A6, the ANK engine was engineered for balanced performance and ref…
Production years 2008–2012 meet Euro 4 standards .
The Audi ANK is a 1,984 cc inline-four petrol engine engineered for compact and mid-size models (2008-2012). It combines FSI direct fuel injection with DOHC valvetrain to deliver responsive throttle characteristics and smooth operation. Designed to meet Euro 4 emissions standards, it balances performance with fuel efficiency in naturally aspirated configuration.

The Audi ANK was used across Audi's 8P/8E platforms with longitudinal mounting and shared architecture with Volkswagen Group EA113-derived units. This engine received platform-specific adaptations-shorter accessory drives in the 8P A3 and revised coolant routing in the 3B A6-and from 2010 the facelifted 8E B7 A4 adopted revised intake manifolds, creating interchange limits. Partnerships enabled shared service tooling across VW, Seat, and Skoda applications. 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The ANK engine offers solid performance when properly maintained, but is prone to intake carbon buildup and fuel system wear. Later models (post-2010) show improved durability with updated engine management. Regular use of premium fuel, consistent oil changes with Audi Longlife 01 oil, and periodic intake cleaning significantly improve long-term reliability.
Primary issues include intake valve carbon buildup, high-pressure fuel pump wear, ignition coil failures, and valve cover oil leaks. These are documented in Audi service bulletins and are typical of FSI engines under mixed driving conditions. Preventative maintenance greatly reduces the risk of major repairs.
The ANK engine was used in the Audi A3 (8P), A4 (8E B7), and A6 (3B C6) from 2008 to 2012. It was also shared across Volkswagen Group models including the VW Golf Mk6 and Passat B6. It typically powered 2.0 FSI variants in front-wheel-drive and Quattro configurations.
Yes, the ANK responds well to ECU remapping, with safe gains of +25-35 kW achievable on stock internals. However, due to its naturally aspirated design, significant power increases require forced induction upgrades. Tuning should include fuel system inspection and cooling upgrades to maintain reliability.
In combined driving, the ANK achieves approximately 7.8–8.5 L/100km (36–30 mpg UK). Highway efficiency is better at ~6.5 L/100km (~43 mpg UK), while city driving can exceed 9.5 L/100km (~30 mpg UK). Real-world consumption depends heavily on driving style and fuel quality.
Yes, the ANK is an interference engine. If the timing chain fails or skips, piston-to-valve contact can occur, resulting in severe internal damage. Regular inspection of the chain tensioner and guides is essential to prevent catastrophic failure.
Audi specifies 5W-40 synthetic oil meeting Audi Longlife 01 specification. Oil changes should be performed every 15,000 km or annually to protect the high-pressure fuel pump and valvetrain. Using correct oil prevents sludge formation and maintains optimal engine longevity.
