The Audi CDLA is a 1,968 cc, inline — four turbo — diesel engine produced between 2013 and 2019. It features common rail direct injection, variable geometry turbocharging (VGT), and dual overhead camshafts (DOHC) with 16 valves. In standard tune, it delivers 103 kW (140 PS) and 320 Nm of torque, offering strong low — end responsiveness and efficient highway cruising.
Fitted to models such as the A1 (8X), A3 (8V), and Q3 (8U), the CDLA engine was engineered for compact and subco…
All CDLA models comply with Euro 6 emissions standards .
The Audi CDLA is a 1,968 cc inline-four turbo-diesel developed for transverse-mounted applications in compact Audi models (2013–2019). It combines Bosch CRS 2-20 common-rail injection with a Garrett variable-geometry turbocharger to deliver responsive torque and efficient operation. Designed to meet Euro 6 standards, it integrates SCR/AdBlue technology for NOx control while maintaining drivability.

The Audi CDLA was used across Audi's 8X/8V/8U platforms with transverse mounting and shared architecture with Volkswagen Group siblings. This engine received platform-specific adaptations-shorter intake manifolds in the A1 and revised cooling routing in the Q3-and from 2016 the facelifted A3 8V.5 adopted updated ECU mapping, creating interchange limits. Partnerships within the Volkswagen Group enabled shared use in Volkswagen and Škoda models with identical core architecture. 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 CDLA is generally robust when maintained properly. Pre-2016 models show higher incidence of HPFP wear if oil changes are delayed or low-quality diesel is used. All units are Euro 6-compliant with integrated SCR systems. Regular oil changes with Longlife-05 and use of quality fuel are essential for longevity beyond 200,000 km.
Key issues include high-pressure fuel pump wear, DPF clogging from city driving, EGR valve fouling, and AdBlue system faults. These are documented in Audi service bulletins and field reports. Preventive maintenance significantly reduces failure rates.
The CDLA 2.0 TDI was used in the A1 (8X), A3 (8V), and Q3 (8U) from 2013–2019. It was also shared across Volkswagen Group brands, appearing in the Volkswagen T-Roc and Škoda Yeti. In the UK, it was offered as the 140 TDI variant.
Aftermarket ECU tuning is common on the CDLA 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.
In real-world conditions, the CDLA achieves 4.3–5.1 L/100km (65–55 mpg UK) on mixed driving. Highway efficiency is excellent at ~4.1 L/100km (68 mpg UK). Urban figures may reach 5.6 L/100km (50 mpg UK) depending on driving style and DPF regeneration frequency.
Yes. The CDLA is an interference engine. If the timing chain fails or jumps, piston-to-valve contact is likely, resulting in severe internal damage. Although the chain is designed for the engine's life, any abnormal noise from the front cover warrants immediate inspection.
Audi specifies SAE 5W-30 oil meeting Longlife-05 standards. This low-SAPS formulation protects the turbocharger, fuel pump, and emissions systems. Oil must be changed every 15,000 km or annually to ensure optimal engine protection and longevity.
