Audi A1 Engines for Sale | Engine Finders
Whether you're replacing a failed N47D20C diesel due to timing chain tensioner wear or upgrading from a worn B47D20A, Engine Finders sources Audi A1 replacement engines matched precisely to your chassis and production year.
Audi A1 Replacement Engines
The Audi A1 (8X chassis, 2010-2018; GB chassis, 2018-present) evolved through two distinct generations, each with unique engine configurations and failure patterns. Early 8X models (2010-2014) used the EA111 petrol and EA189 diesel families, while the facelifted 8X (2015-2018) introduced the N47D20C diesel - prone to timing chain tensioner failure (OEM 11347585994), per Audi Service Bulletin SWE-18-01. The second-generation GB A1 (2018-present) shifted to the B47D20A diesel and EA888 evo3 petrol engines, with the former exhibiting EGR cooler clogging due to tighter packaging. Unlike the A3, the A1’s shorter gearing in both generations accelerates wear on turbochargers and timing components, especially in stop-start urban driving common among A1 owners.
Audi A1 Models & Engines Codes
Engine codes for the A1 vary significantly by generation and market. Below are verified codes exclusive or uniquely tuned for the A1:
- N47D20C: 2.0L diesel (143 hp) in 8X A1 (2015-2018); known for premature timing chain tensioner failure (OEM 11347585994) due to higher load from short gearing.
- B47D20A: 2.0L diesel (150 hp) in GB A1 (2018-present); features revised turbo calibration but suffers from EGR cooler carbon buildup unique to A1’s compact engine bay.
- CAHA: 1.6L TDI (105 hp) in early 8X A1 (2010-2014); susceptible to DPF clogging in urban cycles, more so than in A3 due to lower exhaust temps.
- CZDA: 1.4L TFSI (122 hp) in 8X A1 (2012-2018); common carbon buildup on intake valves, exacerbated by A1’s frequent short-trip usage.
- DKUA: 1.5L TFSI (150 hp) in GB A1 (2018-present); cylinder deactivation system prone to oil consumption if not maintained per Audi’s 10,000-mile service interval.
- CAXC: 1.2L TFSI (86 hp) in base 8X A1 (2010-2014); rare but suffers from high-pressure fuel pump failures linked to low-quality fuel in UK markets.
While some codes like N47D20C appear in other Audis, the A1’s specific ECU mapping and drivetrain calibration create distinct wear patterns - critical when sourcing replacements.
Buy Used and Second-Hand Audi A1 Engines
For A1 owners, engine type choice is critical due to model-specific vulnerabilities:
- Used: Suitable only for low-mileage GB A1 engines with full service history; avoid N47D20C units without tensioner replacement proof.
- Reconditioned: Ideal for 8X A1 - includes new tensioners (11347585994) and EGR valves calibrated for A1’s airflow.
- Rebuilt: Recommended for B47D20A engines, addressing EGR cooler redesign per Audi TSB 2020-07.
- Remanufactured: Best for high-mileage A1s; full restoration to OEM specs with A1-specific oil pump upgrades.
Always verify compatibility with your A1’s chassis (8X/GB) and production month - engine mounts and ancillary brackets differ even within model years.
