The Audi CAND is a 1,798 cc, inline — four turbocharged petrol engine produced between 2010 and 2016. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing on both intake and exhaust camshafts. In standard output form it delivers 125 kW (170 PS), with torque of 250 Nm, engineered for responsive performance and fuel efficiency in Audi's compact and mid — size lineup.
Fitted to models such as the A3 (8V), A4 (B8), and Q3 (8U), the CAND…
All production years (2010–2016) meet Euro 5 emissions standards .
The Audi CAND is a 1,798 cc inline-four turbocharged petrol engine engineered for compact and mid-size models (2010–2016). It combines TSI direct injection with dual VVT to deliver strong mid-range torque and responsive throttle characteristics. Designed to meet Euro 5 emissions standards, it balances real-world performance with regulated efficiency.

The Audi CAND was used across Audi's 8V/B8 platforms with transverse mounting in front-wheel-drive configurations and longitudinal in quattro models. This engine received platform-specific adaptations—modified engine mounts in the Q3 and revised intake manifolds in the A3—and from 2013 the facelifted A4 B8.5 adopted updated ECU calibration, 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 CAND is generally robust when maintained properly, but known for timing chain and intake carbon issues if neglected. Early models (2010–2012) are more prone to tensioner wear. Post-2013 updates improved reliability. Regular oil changes, intake cleaning, and longer drives help prevent carbon buildup and ensure longevity beyond 200,000 km.
The most documented issues are timing chain tensioner wear, intake valve carbon buildup, turbocharger bearing wear, and high-pressure fuel pump failure. These are detailed in Audi service bulletins and confirmed through DVSA failure data. Preventative maintenance significantly reduces risk of major repairs.
The CAND 1.8 TFSI 170 PS was used in the A3 (8V), A4 (B8/B8.5), A5 (8T), and Q3 (8U) from 2010 to 2016. It was succeeded by EA888 Gen 3 engines. All models require 95 RON fuel for full performance and emissions compliance.
Aftermarket ECU tuning is common on the CAND 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.
Good. In an A4 1.8 TFSI, combined consumption is ~6.5 L/100km (~43 mpg UK). Highway runs can achieve ~5.8 L/100km (~49 mpg UK). Real-world mixed driving typically yields 38–44 mpg UK. Economy drops with aggressive driving and cold starts.
Yes. The CAND is an interference engine. If the timing chain fails, pistons contact open valves, causing catastrophic damage. Adhering to the 240,000 km or 10-year replacement interval is essential. Any chain noise or missed service should prompt immediate inspection.
Audi specifies SAE 5W-30 oil meeting VW 502 00 / 505 00 standards. This low-SAPS oil protects the turbo, timing chain, and emissions systems. Change every 15,000–20,000 km or annually. Using incorrect oil can lead to sludge, chain wear, and turbo failure.
