The Audi BPG is a 1,984 cc, inline-four petrol engine produced between 2008 and 2012. It belongs to the EA113 engine family and features double overhead camshafts (DOHC), multi-point fuel injection (MPI), and a variable intake manifold for balanced performance. In standard tune it delivers 103 kW (140 PS) at 5,800 rpm and 180 Nm of torque between 3,200–5,300 rpm, providing responsive mid-range acceleration for everyday driving.
Fitted to models such as the 8P A3, 8E A4, and Typ 53 TT, the BPG was engineered for drivers seeking a balance of fuel efficiency, smoothness, and urban drivability. It complies with Euro 5 emissions standards through precise lambda control, a close-coupled catalytic converter, and exhaust gas recirculation (EGR). The engine’s compact design and transverse mounting made it ideal for Audi’s C-segment and compact performance platforms during the late 2000s.
One documented concern is premature wear of the timing belt tensioner pulley, which may lead to belt slippage or fracture. This issue, highlighted in Audi Service Information Bulletin 2010-07-01, is typically associated with extended service intervals or use of non-OEM replacement parts. Audi revised the tensioner assembly in 2010, introducing a redesigned roller bearing and improved sealing to enhance durability across the EA113 engine series.
Production years 2008–2009 meet Euro 5 standards; 2010–2012 models maintain Euro 5 compliance across all markets (VCA UK Type Approval #VCA/EMS/5679).
The Audi BPG is a 1,984 cc inline-four petrol engine engineered for compact and mid-size Audi models (2008–2012). It combines multi-point fuel injection with a variable intake manifold to deliver responsive mid-range performance. Designed to meet Euro 5 standards, it balances fuel economy with smooth drivability in transversely mounted applications.

The naturally aspirated design provides linear throttle response and low maintenance complexity, but requires strict adherence to the 120,000 km or 5-year timing belt service interval to prevent catastrophic engine damage. Audi Longlife 01 (5W-40) oil is essential to maintain camshaft and valve train longevity. The MPI system is robust but sensitive to carbon buildup on intake valves over time, especially in short-trip driving. EGR and catalytic converter systems must be monitored to maintain Euro 5 compliance and prevent DTCs. Post-2010 models feature an upgraded tensioner pulley; earlier units should be retrofitted per Audi SIB 2010-07-01 to reduce risk of belt failure.
Oil Specs: Requires Audi Longlife 01 (5W-40) specification (Audi SIB 2010-07-01). Supersedes ACEA A3/B3 requirements.
Emissions: Euro 5 certification applies to all production years (2008–2012) (VCA Type Approval #VCA/EMS/5679).
Power Ratings: Measured under SAE J1349 standards. Output consistent across all markets (Audi TIS Doc. A113-8800).

The Audi BPG was used across Audi's 8P/8E platforms with transverse mounting and shared architecture within the Volkswagen Group. This engine received platform-specific adaptations-shorter accessory belts in the 8P A3 and revised ECU mapping in the 8E A4-and from 2010, the facelifted 8P LCI models adopted updated emissions calibration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block near the exhaust manifold (Audi TIS A113-8805). The 8th VIN digit indicates engine type ('B' for BPG series). Pre-2010 models have silver valve covers with black camshaft seals; post-2010 units use black valve covers. Critical differentiation from EA111: BPG has a taller intake manifold and MPI system, while EA111 uses direct injection. Service parts require production date verification - timing belt kits for engines before 09/2010 are incompatible with later units due to tensioner redesign (Audi SIB 2010-07-01).
The BPG's primary reliability risk is timing belt tensioner wear on early builds, with elevated incidence in high-mileage applications. Internal Audi quality reports from 2011 noted a significant share of pre-2010 engines requiring premature belt replacement before 100,000 km, while UK DVSA records link a notable portion of emissions-related MOT failures to EGR clogging in city-driven vehicles. Extended service intervals and frequent short trips increase valve train and EGR stress, making maintenance adherence critical.
