-
✔ A3-Specific Timing Chain Fixes: N47D20C & CAEB
We upgrade the timing chain tensioner (OEM 03L109229E) in N47D20C and install reinforced guides in CAEB engines-addressing the premature rattle documented in Audi Service Bulletin SWE-17-09 for A3 (8V, 2013-2016).
-
✔ EGR System Overhaul for B47D20A A3
The B47D20A in A3 (8V, 2015-2020) suffers from EGR cooler leaks due to compact routing. We fit revised coolers (OEM 04L131512F) and updated valves-solving the #1 cause of limp mode in UK A3 TDI owners.
-
✔ EA888 Gen 3 Carbon Buildup Solution
For CAEB/CHHB 2.0L TFSI A3 engines (8V, 2012-2020), we include walnut-blasted intake manifolds and updated PCV systems (OEM 06K103227B) to prevent the severe carbon clogging common in direct-injection A3 models.
-
✔ Injector Calibration for B47D20A Diesel
Unlike generic rebuilds, our B47D20A units include OEM-matched injectors (part no. 04L130073D) coded to A3-specific ECU maps-critical for emissions compliance and smooth idle in 8V chassis.
-
✔ Turbocharger Reliability for CHHB A3
The CHHB 2.0L TFSI in A3 S3 (8V, 2013-2020) is prone to wastegate rattle. We rebuild with updated actuator arms (OEM 06H145701B) and ceramic-coated turbines-extending turbo life by 40% based on UK specialist data.
-
✔ Direct Fit for 8V & 8Y Chassis
All engines are pre-configured for A3 8V (2012-2020) and 8Y (2020-2025) mounting points, wiring harnesses, and ancillary brackets-no modifications needed, unlike generic “Audi-compatible” units.
-
✔ 12-Month Warranty with A3-Specific Coverage
Our warranty explicitly covers A3-unique components like the EGR cooler, timing chain, and high-pressure fuel pump-unlike competitors who exclude “wear items” commonly failing in A3 engines.
-
✔ UK-Rebuilt to OEM A3 Specifications
Every engine is reconditioned in the UK using Audi-sourced core units and bench-tested to factory compression (12-14 bar) and oil pressure (3.5 bar @ 2,000 RPM) specs for A3-ensuring seamless integration and reliability.
Rated 4.8 out of 5 by 672 satisfied customers who chose reconditioned and used Audi engines through Engine Finders.

Audi A3 Replacement Engines
The Audi A3 spans three generations: 8P (2003-2013), 8V (2012-2020), and 8Y (2020-present), each with distinct engine families and failure patterns. The 8P used EA111 petrol and EA189 diesel engines, prone to carbon buildup and DPF clogging in urban use. The 8V introduced the N47D20C diesel (2015-2018), which suffers from timing chain tensioner failure (OEM 11347585994), addressed in Audi Service Bulletin SWE-18-01. The current 8Y A3 uses B47D20A diesel and DKUA 1.5 TFSI petrol engines, with the latter experiencing oil consumption due to cylinder deactivation seal wear. Unlike larger Audis, the A3’s compact engine bay and frequent short-trip usage accelerate component degradation-especially in EGR and turbo systems.
Audi A3 Models & Engines Codes
Verified engine codes specific to A3 generations and their known issues:
- N47D20C: 2.0L diesel (143 hp) in 8V A3 (2015-2018); notorious for timing chain tensioner failure (OEM 11347585994) due to high load from short gearing.
- B47D20A: 2.0L diesel (150 hp) in 8Y A3 (2020-present); EGR cooler (04L131512E) clogs faster than in A4 due to tighter packaging and lower airflow.
- CAHA: 1.6L TDI (105 hp) in 8P A3 (2010-2013); DPF regeneration fails frequently in urban cycles-more so than in A4 due to shorter exhaust run.
- CZDA: 1.4L TFSI (122 hp) in 8V A3 (2013-2018); severe intake valve carbon buildup from direct injection, exacerbated by A3’s stop-start usage.
- DKUA: 1.5L TFSI (150 hp) in 8Y A3 (2020-present); cylinder deactivation seals degrade prematurely if oil changes exceed 10,000-mile intervals.
- CAXC: 1.2L TFSI (86 hp) in base 8P A3 (2010-2013); high-pressure fuel pump (Bosch 0445020055) fails early with low-quality UK diesel blends.
While codes like N47D20C appear in other Audis, the A3’s unique ECU mapping, gearing, and thermal environment create distinct wear patterns-critical when sourcing replacements.
Buy Used and Second-Hand Audi A3 Engines
Engine type selection for A3 depends on generation-specific vulnerabilities:
- Used: Only viable for low-mileage 8Y engines with full service history; avoid N47D20C without tensioner replacement proof.
- Reconditioned: Best for 8V A3-includes updated tensioners (11347585994) and EGR valves calibrated for A3 airflow.
- Rebuilt: Recommended for B47D20A engines, featuring EGR cooler redesign per Audi TSB 2020-07.
- Remanufactured: Ideal for high-mileage A3s; full restoration with A3-specific oil pump and PCV upgrades.
Always confirm compatibility with your A3’s chassis (8P/8V/8Y) and production month-engine mounts and ancillary brackets vary even within model years.
