Audi Engines We Cover

Real engines from our warehouse, tested and ready to ship. Our Audi inventory spans every major engine family Audi has produced for the U.S. market.

EA888 2.0T TFSI (Gen 1/2/3)

A3, A4, A5, Q3, Q5, TT (2008+). VW-Audi Group's modular 2.0L turbo four across THREE non-interchangeable generations: Gen 1 (CCTA/CBFA), Gen 2 (CAEB/CCZA — oil consumption), Gen 3 (CXBB/CJEB). Verify code by VIN, not displacement.

EA839 3.0T Supercharged/Turbo V6

S4 B8 (2010-2016 supercharged), S4 B9 (2017+ single-turbo), A6/A7 3.0T, Q5 3.0T. B8 uses supercharger, B9 uses turbo — DIFFERENT engine architecture despite shared displacement and family name.

3.2L V6 FSI (ALT/AVK)

A4 3.2 (2005-2008), A6 3.2 (2005-2008), TT 3.2, Q7 3.6 shares related family. Naturally-aspirated V6 FSI — direct injection. Carbon buildup on intake valves expected past 60K miles.

4.2L V8 FSI (BAR)

S5 (B8), RS4 (B7 2006-2008), R8 4.2. Naturally-aspirated 4.2L V8 with FSI direct injection — high-RPM engine. Track abuse and carbon buildup are the two things to verify. We inspect ring lands via borescope on high-mileage units.

4.2L TDI V8 Diesel

Q7 4.2 TDI (2007-2013), A8 4.2 TDI. Twin-turbo V8 diesel — European specification primarily, US limited availability. Verify emissions compliance for your state and confirm Dieselgate calibration status.

5.2L V10 FSI (BFM/BUG)

R8 5.2, S6 (C6), S8 (D3). Lamborghini Gallardo-shared 5.2L V10 (BUG variant) or Audi-specific 5.2L V10 (BFM variant). Very rare donor units — R8 sourcing is specialist. High-value engine, specialist sourcing only.

2.8L V6 AAH (Vintage A4/A6)

A4 2.8 (1996-2001), A6 2.8 (1995-2001), Cabriolet 2.8. Vintage 30-valve V6 — timing belt driven, mandatory belt + tensioner + water pump service at install. Iconic 90s Audi V6 sound.

1.8T CDH/CDN Turbo I4

A4 1.8T (1997-2005), TT 1.8T (2000-2006), A3 1.8T. Classic 20-valve turbo four — predecessor to EA113 and EA888. Sludge on neglected units is well-documented; we inspect valve cover and oil passages before listing.

2.0L TDI CAEB/CAGA Diesel

A3 TDI (2010-2015), A4 TDI (2009-2016), Q5 TDI. Common-rail 2.0L turbodiesel. DIESELGATE CONCERN — some CAEB engines were subject to the emissions settlement. Verify calibration state and DEF/DPF status before purchase.

EA113 2.0T TFSI (Early B7)

A4 2.0T B7 (2005-2008), A3 2.0T (2006-2008), TT 2.0T. Early direct-injection turbo four — predecessor to EA888. HPFP (high-pressure fuel pump) cam follower wear is documented — inspect follower and lobe at install.

3.0L TDI V6 CGW/CGX Diesel

Q7 3.0 TDI (2009-2015), A6 3.0 TDI, A7 3.0 TDI, A8 3.0 TDI. Single-turbo V6 diesel. DIESELGATE CONCERN across multiple US model years — verify calibration state and emissions compliance for your state.

Why Buy a Used Audi Engine from Auto Power Source

Audi's engine catalog spans some of the most engineering-diverse hardware in the industry — the modular EA888 2.0T TFSI four that powers volume A4/Q5 across three non-interchangeable generations, the EA839 3.0L V6 that switched architecture from supercharged (B8, 2010-2016) to single-turbo (B9, 2017+), the 4.2L V8 FSI in S5 and RS4, the Lamborghini-shared 5.2L V10 in R8, and both 2.0L and 3.0L TDI diesels that were caught in the Dieselgate emissions settlement. Buying an Audi engine correctly requires knowing the engine code, not just the displacement or year.

Our 600+ Audi engines all come from low-mileage donor vehicles, cataloged by VIN, and held in our climate-controlled warehouse pending sale. Every unit clears our six-step process: VIN-matched to donor and target, ASE-certified compression test on every cylinder, leak-down evaluation, run-stand noise & smoke verification, visual inspection, multi-angle photographs for your approval, and palletized freight. On EA888 units we verify the exact generation code (Gen 1/2/3) and inspect ring condition (Gen 2 oil consumption). On EA113 and 1.8T units we inspect HPFP cam follower wear. On TDI 2.0L and 3.0L units we verify calibration status against the Dieselgate settlement scope. On 4.2L V8 FSI units (S5/RS4) we inspect ring lands via borescope for track abuse. On R8 V10 units we handle sourcing individually.

You pay a fraction of dealer pricing for identical Audi engineering, ship free on a heavy-duty pallet to any address in the continental U.S., and get 30 days from delivery to return — no restocking fees. Up to a 3-year warranty covers you after install. Across 100,000+ Engines+Transmissions In Stock, our fitment-related return rate stays at 0%.

Audi Engine Buying Guide

Five things to verify before buying a used Audi engine:

1. EA888 Gen 1 vs Gen 2 vs Gen 3 non-interchange. The 2.0T TFSI EA888 in A3/A4/A5/Q3/Q5/TT (2008+) has three generations with different intake, injection, and internal design. Gen 1 (CCTA, CBFA — early), Gen 2 (CAEB, CCZA, CCZB — the oil consumption generation), Gen 3 (CXBB, CJEB, CHHB — current). Verify engine code against your VIN. Installing wrong generation will bolt in but breaks emissions and diagnostics.
2. TDI 2.0L and 3.0L Dieselgate calibration status. Audi 2.0L TDI (CAEB, CAGA — A3/A4/Q5) and 3.0L TDI V6 (CGW, CGX — Q7/A6/A7/A8) were included in the VW-Audi Group Dieselgate emissions settlement. Verify calibration state: pre-fix, dealer-updated, or buyback donor. This affects registration eligibility in some states. Confirm before purchase.
3. EA839 3.0T Supercharged (B8) ≠ Turbo (B9). The S4 3.0T uses supercharged EA839 in B8 platform (2010-2016) and turbocharged EA839 in B9 (2017+). Same displacement, same family name, but the boost architecture is completely different. Verify chassis platform, not just S4 badge — an incorrect swap will not hit factory power or emissions.
4. 4.2L V8 FSI track abuse verification (S5/RS4). The 4.2L V8 FSI in B7 RS4 (2006-2008) and B8 S5 is a naturally-aspirated high-RPM engine popular with track enthusiasts. Ring land damage from repeated over-rev events is documented. We inspect via borescope and verify no aftermarket ECU tuning history on every 4.2L V8 unit.
5. R8 5.2L V10 is a specialist unit — expect longer sourcing. The 5.2L V10 FSI in R8 (BFM Audi-specific, BUG Lamborghini-shared) is a collector-grade engine. Very low donor availability, and each unit is individually sourced. Text us your VIN and R8 chassis year — turnaround is typically 4-8 weeks, longer than volume engines.

Our ASE-certified technicians verify every one of these points against your VIN before any engine ships.
