The Audi CEPB is a 1,968 cc, inline — four turbo — diesel engine produced between 2010 and 2018. It forms part of the Volkswagen Group's EA288 engine family, designed for efficiency and durability across compact and mid — size platforms. Featuring common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC), it delivers 103 kW (140 PS) and 320 Nm of torque, with start — stop technology and energy recovery systems enhancing fuel ec…
Production years 2010–2014 meet Euro 5 standards; 2015–2018 models comply with Euro 6b depending on market .
The Audi CEPB is a 1,968 cc inline-four turbo-diesel engineered for compact and executive models (2010–2018). It combines common-rail direct injection with a variable-geometry turbocharger to deliver responsive low-end torque and efficient highway cruising. Designed to meet Euro 5 and Euro 6 standards, it balances emissions compliance with real-world drivability.

The Audi CEPB was used across Audi's 8V/B8/C7 platforms with transverse mounting in front-wheel-drive models and longitudinal in quattro variants. This engine received platform-specific adaptations-integrated starter-generator (ISG) in mild-hybrid variants from 2016-and from 2015 the facelifted B8.5 and C7.5 models adopted SCR/AdBlue systems, creating emissions system 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 CEPB is generally robust, especially compared to earlier TDI engines. Pre-2015 models are prone to EGR and DPF issues if used for short trips. Post-2015 SCR-equipped variants are more complex but reliable when maintained. Timing chains are durable, but tensioners may wear beyond 200,000 km. Using correct oil and driving regularly on highways greatly enhances longevity.
Primary issues include EGR/intake carbon buildup, DPF saturation, and AdBlue system faults in SCR models. Secondary concerns are timing chain tensioner rattle and occasional high-pressure fuel pump wear. These are documented in Audi service bulletins, particularly SIB 2015-01-02 for EGR improvements and SIB 2014-03-01 for oil specification enforcement.
The CEPB 2.0 TDI 140 PS was used in the Audi A3 (8V, 2013–2018), A4 (B8/B8.5, 2010–2018), and A6 (C7/C7.5, 2011–2018). It was available in both front-wheel-drive and quattro configurations. Models from 2015 onward with Euro 6 compliance feature SCR/AdBlue systems, while earlier versions meet Euro 5 with DPF-only emissions control.
Aftermarket ECU tuning is common on the CEPB 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.
Excellent. In an A4 2.0 TDI (140 PS), combined consumption is ~4.2 L/100km (67 mpg UK). Highway runs can achieve ~3.8 L/100km (74 mpg UK), while city driving may reach ~5.0 L/100km (56 mpg UK). Real-world figures for mixed driving typically range from 50–65 mpg UK, depending on driving style and condition.
No. The CEPB uses a non-interference valvetrain design. If the timing chain fails, piston-to-valve contact is unlikely, reducing the risk of catastrophic engine damage. However, any timing issue still requires immediate repair to prevent valve or piston damage from secondary contact or loss of compression.
Audi specifies VW 504 00 / 507 00 (SAE 5W-30) synthetic oil. This low-ash formulation is essential for protecting the turbocharger, high-pressure fuel pump, and DPF. Change intervals are 15,000 km or annually under normal conditions, but shorten to 10,000 km for frequent short trips or towing.
