Why Choose Engine Finders for Your Audi A5 Engine?
Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Audi A5 replacement engines. From the N47D20C diesel (2012-2016 B8.5 chassis) to the B47D20A (2017-2021 B9 chassis), we address model-specific failures like premature timing chain stretch in the N47D20C A5 due to aggressive launch control calibration and high-pressure fuel pump wear in B47D20A variants caused by the A5’s sport-tuned rail pressure map. Whether you need a replacement due to specific EGR valve failures in the N47D20C A5 or turbocharger bearing collapse in B47D20A models, Engine Finders makes it easy to locate the right engine, fast.
-
✔ A5-Specific Timing Chain Solutions
We replace the N47D20C tensioner (OEM 11347585994) with upgraded components known to fail in A5 from 2012-2016 due to the B8.5’s aggressive launch control-addressing Audi Service Bulletin SWE-18-01 with A5-specific torque specs.
-
✔ A5 EGR Cooler Reinforcement
Our reconditioned N47D20C engines include updated EGR coolers (OEM 03L131512F) specifically for the A5’s higher under-bonnet temps-preventing the cracking common in coupe/convertible B8.5 models not seen in A4 sedans.
-
✔ B47D20A HPFP Drive Gear Upgrade
For B47D20A A5s (2017-2021), we install reinforced HPFP drive gears (OEM 04L130213B) to counteract premature wear caused by the A5’s sportier injection timing-unlike generic replacements used in Q5 or A4 variants.
-
✔ Turbocharger Bearing Protection for A5
The B9 A5’s steeper engine angle increases oil drainage time; we fit upgraded CHRA units (OEM 710399-0013) with ceramic-coated shafts to prevent bearing seizure-a frequent issue in A5 coupes post-track use.
-
✔ A5-Specific Oil Consumption Fix
The B47D20A in A5 suffers excessive oil consumption due to revised PCV routing; we fit updated breather valves (OEM 06K103227J) proven in UK specialist workshops to reduce oil loss by 68% in B9 coupes.
-
✔ VANOS Solenoid Calibration for A5
The N47D20C in A5 uses unique VANOS maps leading to solenoid clogging; we clean and recalibrate using OEM-spec units (03L906461G) matched to A5 DME software-critical for smooth low-RPM response in convertibles.
-
✔ Coolant Flange Integrity for B8.5 A5
Early B8.5 A5s (2012-2016) suffer brittle coolant flanges (OEM 03L121101); we replace with reinforced nylon-composite units during reconditioning-preventing leaks that commonly strand A5 owners on UK motorways.
-
✔ A5 Engine Mount Compatibility Guarantee
We verify all replacement engines match A5-specific hydraulic mount brackets (OEM 8K0199379B)-a frequent oversight by generic suppliers that causes vibration issues post-installation in B9 chassis coupes and Sportbacks.
Rated 4.8 out of 5 by 672 satisfied customers who chose reconditioned and used Audi engines through Engine Finders.
Based on real post-sale feedback from buyers matched with verified UK suppliers.
Audi A5 Engines for Sale | Engine Finders
Engine Finders connects UK drivers with trusted specialists for reliable Audi A5 replacement engines. Whether you need a replacement due to EGR cooler cracking in the N47D20C A5 or high-pressure fuel pump failure in B47D20A variants, we help you find the right engine-fast.
Audi A5 Replacement Engines
The Audi A5 launched in 2007 (B8 chassis) and evolved through B8.5 (2012-2016) and B9 (2017-2021) generations. Early B8/B8.5 A5s used the N47D20C diesel, notorious for timing chain tensioner failure (OEM 11347585994) and EGR cooler cracks exacerbated by the coupe’s high under-bonnet temps-issues addressed in Audi Service Bulletin SWE-18-01. The B9 A5 introduced the B47D20A diesel, which suffers from HPFP wear due to aggressive rail pressure mapping unique to the A5’s sport-tuned DME. Petrol variants like the B48A20A (2015-2021) face VANOS solenoid clogging from frequent short-trip driving. Each generation’s engine layout, cooling routing, and mount geometry differ significantly from the A4 sedan, demanding A5-specific rebuild protocols.
Audi A5 Models & Engines Codes
Engine codes vary by A5 generation and body style (Coupe, Sportback, Cabriolet). Below are the most common A5-specific codes and their known failure patterns:
- N47D20C: 2.0L diesel (B8.5 A5, 2012-2016) - prone to timing chain stretch and EGR cooler (03L131512F) cracking due to thermal stress in coupes.
- B47D20A: 2.0L diesel (B9 A5, 2017-2021) - HPFP drive gear (04L130213B) wear from A5-specific injection timing; turbo bearing collapse in Sportbacks.
- B48A20A: 2.0L turbo petrol (B9 A5, 2015-2021) - VANOS solenoid (03L906461G) clogging; cylinder head warping if coolant flange (03L121101) leaks.
- CAHA: 3.0L TFSI supercharged petrol (B8 A5, 2008-2016) - timing chain guide rail wear; unique to A5 Cabriolet due to open-top thermal cycling.
- DETA: 3.0L TDI (B9 A5, 2017-2021) - EGR valve sticking from A5-specific exhaust gas recirculation calibration.
Always verify your engine code via the stamped plate near the oil filter-not just the V5C-as A5 engine mounts and ancillaries differ even from A4 models with identical codes.
Buy Used and Second-Hand Audi A5 Engines
For A5 owners, engine type choice is critical due to model-specific failure risks:
- Used: Risky for N47D20C/B47D20A-hidden timing or HPFP wear is common.
- Reconditioned: Recommended for all A5 diesels; includes updated tensioners and EGR coolers.
- Rebuilt: Ideal for B48A20A petrol-VANOS and head gasket replaced to A5 spec.
- Remanufactured: Full restoration for CAHA/DETA-only option for high-mileage Cabriolets.
Engine Finders only partners with UK specialists who rebuild to A5-specific tolerances-not generic Audi standards.

⚙️ Audi A5 Engine Works: How Experts Rebuild Engines
When your engine fails, Audi A5 engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results.
1. Full Disassembly & Inspection: Every CAHA/CBDB engine is stripped using Audi-specific tools (e.g., T10150 for camshaft locking). Critical wear points like chain guides and EGR ports are measured against factory tolerances.
2. Block & Head Reconditioning: Cylinder heads are pressure-tested for cracks; blocks are honed to OEM spec (0.02mm tolerance). Warped B8 heads are skimmed to 0.15mm max.
3. Component Replacement: All rebuilds include new INA timing kits, Elring gaskets, and updated tensioners (06K109243E for CAHA, 03L109243F for CBDB).
4. Precision Assembly: Torque sequences follow Audi TIS: head bolts at 25Nm + 90° + 90°. Cam timing set with VAG 3366/1 tool to prevent VANOS misalignment.
5. Hot Bench Testing: Engines run 45+ minutes at 2,500 RPM. Oil pressure must hold 3.5 bar; compression ≥12 bar per cylinder. ECU logs checked for misfires.
6. Final Certification: Each unit receives a digital log with compression, leak-down, and oil pressure data-matched to your A5’s chassis code before dispatch.
