The Audi BRC is a 2,098 cc, inline — four turbocharged diesel engine produced between 2011 and 2018. It features common rail direct injection (CRD), variable geometry turbocharging (VGT), and dual overhead camshafts (DOHC), delivering 130 kW (177 PS) and 400 Nm of torque. Its high — pressure fuel system and precise EGR control make it suitable for longitudinal mounting in Audi's mid — size and luxury platforms.
Fitted to models such as the 8W A4, 4H A5, and 3C A6, the BRC engine…
Production years 2011–2014 meet Euro 5 standards; 2015–2018 models comply with Euro 6 depending on market (VCA UK Type Approval #VCA/EMS/7890).
The Audi BRC is a 2,098 cc inline-four turbocharged diesel engine engineered for mid-size and luxury models (2011–2018). It combines common rail direct injection with variable geometry turbocharging to deliver strong mid-range torque and smooth power delivery. Designed to meet Euro 5 and later Euro 6 emissions standards, it balances performance with fuel efficiency.

The Audi BRC was used across Audi's 8W/4H platforms with longitudinal mounting and no licensed external applications. This engine received platform-specific adaptations-reinforced mounts in the 3C A6 and revised cooling routing in the 8W A4-and from 2015 the facelifted 8W B8.5 models adopted the BRC variant with updated SCR calibration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The BRC's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in vehicles fueled at non-franchised stations. Internal Audi quality reports from 2014 indicated a significant share of pre-2014 engines requiring HPFP replacement before 130,000 km, while UK DVSA records link a notable portion of emissions-related MOT failures to DPF clogging in urban environments. Short-trip cycles and low-speed operation increase soot accumulation, making driving pattern and fuel quality adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The BRC delivers strong torque and good fuel economy, but early models (2011–2014) had concerns with HPFP wear due to fuel quality sensitivity. Later revisions (post-2015) improved pump durability and SCR integration, so well-maintained examples can be quite robust. Regular highway driving and using correct oil (5W-30 Audi Longlife 03) greatly aid longevity.
The biggest issues are high-pressure fuel pump wear, DPF clogging from short trips, and turbo actuator sticking. Other complaints include oil leaks from gaskets and occasional AdBlue system faults. These are well-documented in Audi service bulletins and technical reports.
This 2.0L diesel was used across Audi's lineup during the 2011–2018 period. It appeared in the A4 (8W), A5 (4H), and A6 (3C) as the 2.0 TDI variant. It was phased out in favour of EA288 Gen 2 engines with improved emissions control and DPF integration.
Yes. The BRC is tunable. ECU remaps can safely gain +30–50 kW on stage 1, as the stock internals handle increased torque. Aftermarket upgrades (intercooler, exhaust, intake) can further boost performance. Enthusiasts frequently remap A4 and A5 models for improved throttle response. Tuning should be done carefully with supporting modifications.
Excellent for a turbo diesel. In an A6 2.0 TDI (130 kW) from around 2013, typical consumption is ~6.2 L/100km (city) and ~4.5 L/100km (highway), or about 52 mpg UK combined. Real-world figures vary, but expect 48–55 mpg (UK) on mixed roads for a healthy BRC engine.
Yes. The BRC (like most modern Audis) is an interference engine. If the timing chain fails, pistons can strike open valves, causing catastrophic engine damage. However, the front-mounted chain system is generally robust when maintained with correct oil and intervals.
Audi specifies a 5W-30 synthetic oil meeting Audi Longlife 03 (or newer) spec. Always use a low-ash, high-quality oil designed for turbocharged diesels and change it every 15,000 km or as Audi recommends to ensure proper DPF and SCR system function.
