The Audi CRTE is a 1,968 cc, inline — four turbocharged diesel engine produced between 2023 and 2025. It belongs to the Volkswagen Group’s EA288 Evo engine family, featuring modular diesel architecture, dual — loop EGR, and a variable geometry turbocharger (VGT) with electric assist. In its standard configuration, it produces 176 kW (240 PS) and 500 Nm of torque, with optimized combustion efficiency and reduced NOx emissions through Bosch CRS4 high — pressure injection.…
All CRTE variants meet Euro 6d emissions standards .
The Audi CRTE is a 1,968 cc inline-four turbocharged diesel engine from the EA288 Evo family (2023–2025). It integrates dual-loop EGR, electrically assisted VGT, and 48 V MHEV technology to deliver responsive performance with reduced emissions. Designed for Euro 6d compliance, it balances performance and efficiency in Audi’s executive and luxury SUV lineup.

The Audi CRTE was used across Audi's C8 platform with longitudinal mounting and shared architecture with Volkswagen Group siblings. This engine received platform-specific adaptations-revised intake tracts in the A6 and enhanced cooling in the Q8-and from 2024 received updated fuel system components, creating interchange limits. 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 CRTE delivers strong performance and good efficiency, but early models (2023-2024) had reliability concerns, especially high-pressure fuel pump wear. Later revisions (post-2024) improved pump durability, so well-maintained examples can be quite robust. Regular servicing and using high-quality oil (0W-30 VW 507 00) greatly aid longevity.
The biggest issues are high-pressure fuel pump wear (leading to misfires or hard starting), EGR valve clogging, and electric turbocharger control faults. Other complaints include oil leaks from gaskets and occasional DPF regeneration issues. These are well-documented in Audi service bulletins.
This 2.0L diesel was used in the Audi A6 (C8), A7 (C8), and Q8 (facelift) from 2023 to 2025. It was primarily offered as the 50 TDI e-tron variant. The engine is part of the EA288 Evo family shared across Volkswagen Group brands but remains specific to Audi's executive and luxury SUV lineup in this power output.
Aftermarket ECU tuning is common on the CRTE 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.
Competitive for a performance diesel. In an A6 50 TDI e-tron (176 kW) from 2024, typical consumption is ~7.2 L/100km (city) and ~5.6 L/100km (highway), or about 40 mpg UK combined. Real-world figures depend on driving style, but expect 36-42 mpg (UK) on mixed roads for a healthy CRTE engine.
Yes. The EA288 series (like most modern Audis) is an interference engine. This means if the timing chain jumps or breaks, pistons can strike open valves, causing catastrophic engine damage. That's why chain maintenance is critical - any warning rattles should be addressed immediately.
Audi specifies a 0W-30 synthetic oil meeting VW 507 00 (diesel) or 505 00 (multi-vehicle) specification. Always use a quality oil designed for turbocharged diesel engines and change it at regular intervals (around 15,000 km or as Audi recommends) to ensure proper fuel pump and turbo lubrication.
