If you work on VAG turbo-fours all day, you quickly learn which assemblies pay you back in hours saved and comebacks avoided. The Engine Assembly for EA888 (1.8T) II CDAA AUDI Volkswagen is one of those—especially for CDAA/CDAB/CDHB families where oil consumption and timing hardware updates tell the whole story.

Why this assembly is trending
Across Europe, the Middle East, and increasingly Southeast Asia, shops are choosing fully tested long-blocks over piecemeal rebuilds. To be honest, it’s the predictable economics: faster install, fewer variables, and a warranty you can show a skeptical customer. This unit, built in Shijiazhuang (Hebei, China), ships as a ready-to-drop solution for CDAA, CDA, CDAB, CDHB, CPKA, CPRA, CJEB, and CJSA codes on popular Audi and Volkswagen platforms.

Core specifications (field-verified)
| Engine family | EA888 Gen II, 1.8 TSI (CDAA series) |
| Displacement | ≈ 1798 cm³ (bore × stroke ≈ 82.5 × 84.1 mm) |
| Architecture | Inline-4, DOHC, 16V, chain-driven |
| Compression ratio | ≈ 9.6:1 (variant-dependent) |
| Power/torque | ≈ 118 kW / 250 Nm (real-world use may vary) |
| Fuel system | Direct injection, turbocharged (K03-family) |
| Recommended oil | VW 502 00 / 504 00 spec, 5W-30 or 5W-40 (climate dependent) |
Materials and build: graphite cast-iron block, aluminum head, integrated balancer module, with updated chain/tensioner set and revised oil-control ring pack. Actually, many customers say the oil use drop-off is noticeable after the first 1,000 km.

Process flow and testing
- Precision machining: torque-plate cylinder honing; align-hone main bores; surface finish Ra ≈ 0.4–0.8 μm on deck/head.
- Component matching: graded pistons, ring end gaps set for DI turbo heat load; VVT phaser indexing verified.
- Dynamic balance: rotating assembly balanced to ISO 1940-1 G6.3.
- Bench testing: oil pressure ≥ 2.0 bar @ 2,000 rpm; compression ≥ 11.5 bar/cyl; leak-down ≤ 8% at 100 psi.
- QC standards: ISO 9001 and IATF 16949 aligned; process audits referencing VDA 6.3.
- Expected service life: ≈ 200,000 km with correct oil spec and 10–15k km intervals (market-dependent).
Where it fits
Audi A3/A4/A5/TT and Volkswagen Passat/CC/Tiguan/Golf variants using CDAA-series codes. It also crosses to Skoda/SEAT in some markets, but check ECU calibration and emissions equipment. For most shops, the Engine Assembly for EA888 (1.8T) II CDAA AUDI Volkswagen is truly plug-and-play once peripherals (turbo, injectors, HPFP) are swapped from the original unit.

Vendor comparison (what shops actually weigh)
| Option | Testing/Warranty | What’s new | Lead time | Typical result |
|---|---|---|---|---|
| Oujia EA888 1.8T long-block | Bench-tested; written warranty (region-specific) | Pistons/rings, bearings, chains, seals | Fast (stocked SKUs) | Low comebacks; predictable install time |
| Used take-out | Minimal/no test; short warranty | Unknown wear | Variable | Cheaper upfront; risk of oil use/chain noise |
| Generic rebuild | Shop-dependent | Partial refresh | Longer | Quality variability |
Customization and options
- Emissions hardware prep (Euro 5/6 market setups; EOBD readiness checks).
- Optional turbocharger, injectors, HPFP supply as a bundle.
- Packaging for export with traceable QR and lot serialization.

Real-world feedback
Berlin independent Audi specialist: “Two installs in Q2. Hot oil pressure was solid and the chain noise is gone. Zero returns.” A fleet operator in Dubai noted oil consumption “virtually eliminated” after 5,000 km. It seems that consistent ring-pack prep and phaser indexing matter more than people admit.
Engine Assembly for EA888 (1.8T) II CDAA AUDI Volkswagen ships from 289 Heping East Road, Chang ’an District, Shijiazhuang City, Hebei Province, China. If you’re juggling A4 B8 or Passat B7 schedules, shaving a day off labor is the difference between happy customers and grumpy phone calls.
