The Audi BRE is a 1,968 cc, inline — four turbocharged diesel engine produced between 2010 and 2018. It features double overhead camshafts (DOHC), common rail direct injection, and a variable geometry turbocharger (VGT). Delivering 103 kW (140 PS) and 320 Nm of torque, it was engineered for compact and mid — size vehicle applications requiring strong low — end performance and fuel efficiency.
Fitted primarily to the Audi A3 (8V), A4 (B8), and A6 (C7) models, the BRE engine wa…
Production years 2010–2015 meet Euro 5 standards; 2015–2018 models comply with Euro 6d-TEMP (VCA UK Type Approval #VCA/EMS/6789).
The Audi BRE is a 1,968 cc inline-four turbocharged diesel engine engineered for compact and mid-size models (2010–2018). It combines DOHC valvetrain architecture with Bosch CRS 2.0 common rail injection and a variable geometry turbocharger to deliver strong low-end torque and efficient highway performance. Designed to meet Euro 5 and Euro 6 emissions standards, it balances performance with environmental compliance.

The Audi BRE was used across Audi's 8V/B8/C7 platforms with transverse mounting. This engine received platform-specific adaptations-shorter accessory belts in the A3 and revised ECU mapping for start-stop integration in later A4 models-and from 2015 the facelifted A6 incorporated updated SCR dosing algorithms, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The BRE's primary reliability risk is high-pressure fuel pump failure on early builds, with elevated incidence in mixed urban-highway use. Internal Audi quality reports from 2014 indicated a significant number of pre-2014 engines requiring HPFP replacement before 150,000 km, while UK DVSA records link a notable share of emissions-related MOT failures to EGR cooler leaks in high-mileage vehicles. Extended oil intervals and short-trip driving increase turbo and emissions system stress, making maintenance adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The BRE is generally reliable when maintained properly, but early models (2010-2014) had high-pressure fuel pump concerns. Later revisions (post-2014) improved component durability. Regular servicing, timely oil changes, and using correct diesel (EN 590) significantly enhance longevity. Avoid short trips and ensure AdBlue system maintenance to prevent emissions-related issues.
Key issues include HPFP wear (especially pre-2014), EGR cooler leaks, turbo actuator sticking, and AdBlue system faults. These are documented in Audi service bulletins and field reports. Preventive maintenance, especially EGR and fuel system care, greatly reduces failure risk.
The BRE engine was used in the Audi A3 (8V) from 2013-2018, A4 (B8) from 2010-2015, and A6 (C7) from 2012-2018. It powered the 2.0 TDI 140 PS variants. All models are Euro 5 or Euro 6 compliant. The engine was phased out in favour of newer EA288 Evo units.
Yes. The BRE responds well to ECU remapping, typically gaining 30-40 kW and 80-100 Nm safely with supporting modifications. Stock internals handle increased torque well, but upgraded turbo and intercooler are recommended for higher power levels. Tuning must respect emissions system limits to avoid DPF/SCR faults.
In combined driving, the BRE achieves ~5.2 L/100km (approx. 54 mpg UK). City driving may see 6.0 L/100km (~47 mpg), while highway runs can reach 4.5 L/100km (~62 mpg). Real-world consumption depends on driving style, but it offers excellent efficiency for a 2.0L diesel.
Yes. The BRE is an interference engine, meaning a broken or slipped timing chain can result in piston-to-valve contact and severe internal damage. Although the chain is rated for 200,000 km, inspection is recommended at 150,000 km to prevent costly repairs.
Audi specifies SAE 5W-30 oil meeting Audi Longlife Diesel 05 504 00 specification. Use only VW 504 00-compliant synthetic diesel oil and change every 15,000 km or annually to ensure optimal turbo, chain, and fuel system protection.
