Audi A7 Engines for Sale | Engine Finders

Whether you're battling EGR cooler failures in the B47D20A or timing chain wear in the N47D20C, Engine Finders connects you with UK specialists offering the right Audi A7 replacement engine-tested, warrantied, and built for your specific chassis.

Audi A7 Replacement Engines

The Audi A7 launched in 2010 (C7, 4G chassis) with TDI and TFSI options, followed by the C8 (4K chassis) in 2018 featuring mild-hybrid integration. The C7’s N47D20C diesel (2011-2018) is notorious for timing chain tensioner failure (OEM 11347585994), addressed partially in Audi Service Bulletin SWE-18-01. The C8’s B47D20A (2018-2025) suffers from EGR cooler clogging due to higher recirculation rates unique to A7’s emissions tuning. Unlike the A6, the A7’s lower production volume means fewer updated parts in circulation-making correct rebuild specs critical.

Audi A7 Models & Engines Codes

Key engine codes found exclusively or predominantly in the A7 across generations:

  • N47D20C: 2.0L TDI (C7 A7, 2011-2018) - prone to timing chain stretch; requires updated tensioner (11347585994)
  • CAHA/CAHB: 3.0L TDI V6 (C7 A7) - known for injector carbon buildup and high-pressure fuel pump wear
  • B47D20A: 2.0L TDI mild-hybrid (C8 A7, 2018-2025) - EGR cooler (04L131512D) fails early due to A7-specific calibration
  • CYRB/CYRC: 3.0L TFSI V6 (C8 A7) - turbo wastegate rattle common after 90k miles
  • DLZA: 3.0L TDI with 48V mild-hybrid (C8 RS7) - complex start-stop integration increases starter motor load
  • CRKB: 2.0L TFSI (C7 A7 Sportback) - carbon intake valve coking without direct port injection

While some codes appear in other Audis, the A7’s drivetrain layout, quattro tuning, and thermal management create unique wear patterns not seen in A6 or Q7 applications.

Buy Used and Second-Hand Audi A7 Engines

We offer three A7-specific engine types tailored to your budget and reliability needs:

  • Used: Mileage-matched pull-outs from low-mile C7/C8 A7s-ideal for short-term fixes
  • Reconditioned: Fully rebuilt with updated components for known A7 failure points (e.g., N47 chain kits)
  • Remanufactured: Factory-spec restoration including hybrid system recalibration for C8 mild-hybrid engines

For C7 diesel owners, we strongly recommend reconditioned units due to widespread timing chain and EGR issues in original builds.

Audi A7 Engines in Stock

Our reconditioned A7 engines include model-specific upgrades to prevent repeat failures:

  • New timing chain tensioner (OEM 11347585994) for all N47D20C C7 engines
  • Revised EGR cooler (04L131512D) with anti-clog baffling for B47D20A C8 units
  • Updated piston rings (03L107061F) for high oil consumption in pre-2016 C7 diesels
  • Hybrid system reset protocol for C8 48V engines to ensure seamless DME communication

Every engine undergoes compression testing, leak-down analysis, and idle stability checks on A7-specific diagnostic rigs before dispatch.

Warranty for Replacement Audi A7 Engines

All reconditioned and remanufactured A7 engines come with a standard 12-month parts-and-labour warranty.

  • Covers internal mechanical failure under normal operating conditions
  • Excludes timing chain components on pre-2015 N47D20C engines due to inherent design limitations
  • Requires professional installation with full service history submission

Engine Finders is a price comparison platform. Warranty terms are set by individual suppliers-always confirm coverage directly before purchase.

⚙️ Audi A7 Engine Works: How Experts Rebuild Engines

When your engine fails, Audi A7 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 Strip & Inspection: Every N47D20C block is magnafluxed for C7-specific hairline cracks near oil galleries-common after 100k miles.

2. Timing System Overhaul: Replaced with OEM-spec chain, rails, and tensioner (11347585994) using Audi tool T10340 to prevent misalignment in A7 applications.

3. EGR & Cooling Refresh: C8 B47D20A units get new EGR cooler (04L131512D) and thermostat housing-failure points unique to A7’s thermal load.

4. Hybrid System Calibration: C8 48V engines undergo full DME reset using ODIS-E to sync the starter-generator with new engine parameters.

5. Precision Reassembly: Cylinder head torqued to 25Nm + 90° turn (per Audi spec for A7 TFSI), with new stretch bolts (N91087201).

6. Rigorous Testing: 45-minute hot-idle test on A7-specific dyno rig, checking oil pressure, smoke output, and CAN bus communication stability.
