VOLKSWAGEN DAFA engine (2019–2024) – Specs, Problems & Compatibility Database

The Volkswagen DAFA is a 1,984 cc, inline‑four turbocharged petrol engine produced between 2019 and 2024. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing. In standard form it delivers 180 kW (245 PS) and 370 Nm of torque, enabling strong performance with refined drivability.

Fitted to models such as the Mk8 Golf R, Audi S3 (8Y), and Cupra León, the DAFA was engineered for high output with everyday usability. Emissions compliance was achieved through a gasoline particulate filter (GPF), precise cam phasing, and a close-coupled three-way catalytic converter, meeting Euro 6d standards across all production years.

One documented concern is premature wear of the high-pressure fuel pump (HPFP) drive lobe on the intake camshaft, highlighted in Volkswagen Group Service Bulletin 2021‑04‑03. This stems from marginal lubrication under high-load, high-RPM operation. From late 2022, revised camshaft profiles and updated HPFP internals were introduced to improve durability.

Compliance Note:

All production years 2019–2024 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/9876).

DAFA Technical Specifications

The Volkswagen DAFA is a 1,984 cc inline‑four turbocharged petrol engineered for high-performance hatchbacks and sedans (2019–2024). It combines direct injection (TSI) with a twin-scroll turbocharger to deliver strong mid-range torque and high-rev responsiveness. Designed to meet Euro 6d standards, it balances sporty performance with stringent emissions compliance.

Practical Implications

The twin-scroll IHI IS38 turbo and 350-bar HDEV6 injectors enable rapid torque delivery and high specific output, but demand RON 98 fuel for optimal performance and longevity. Strict adherence to 15,000 km or annual oil changes using VW 504 00/507 00 (0W‑20) is essential to protect the HPFP cam lobe and timing chain. Early DAFA engines (2019–late 2022) are susceptible to HPFP drive lobe wear under aggressive use; post-2022 units incorporate camshaft and HPFP revisions per VW SIB 2021‑04‑03. The GPF requires periodic high-load driving to prevent saturation and regeneration faults.

Data Verification Notes

Oil Specs: Requires VW 504 00 / 507 00 (0W-20) specification (VW Owner’s Manual Mk8 Golf R). Not interchangeable with 5W-40 oils.

Emissions: Euro 6d certification applies to all DAFA production years (VCA Type Approval #VCA/EMS/9876).

Power Ratings: Measured under ECE R85 standards. Full 245 PS output requires RON 98 fuel (VW TIS Doc. 06K‑10250).

DAFA Compatible Models

The Volkswagen DAFA was used across Volkswagen Group's MQB Evo platform with transverse mounting and shared with Audi and Cupra. This engine received platform-specific adaptations—reinforced mounts in the Golf R Mk8, revised cooling in the Audi S3 8Y, and exhaust routing changes in the Cupra León—creating minor service part differences. All adaptations are documented in OEM technical bulletins.

Identification Guidance

Locate the engine code stamped on the front timing cover near the oil filter housing (VW TIS 06K‑10250). The 7th VIN digit for Golf R is 'R'; for Audi S3 it is '8'. DAFA is visually distinguished by its black plastic intake manifold with integrated charge pipe and IHI IS38 turbo (silver housing with twin-scroll outlet). Critical differentiation from CZDA/CYVB: DAFA uses Bosch HDEV6 injectors (350 bar), includes a gasoline particulate filter (GPF), and requires 0W‑20 oil. HPFP part number 06K 127 025 H (pre-2023) vs. 06K 127 025 J (post-2023) indicates service bulletin compliance.

Identification Details

HPFP Upgrade

Issue:

Early DAFA engines (2019–late 2022) suffer from high-pressure fuel pump cam lobe wear due to marginal lubrication under high load.

Evidence:

VW SIB 2021‑04‑03

Recommendation:

Install updated HPFP (part 06K 127 025 J) and inspect camshaft lobe per VW SIB 2021‑04‑03.

Common Reliability Issues - VOLKSWAGEN DAFA

The DAFA's primary reliability risk is high-pressure fuel pump (HPFP) drive lobe wear on the intake camshaft, with elevated incidence in track-driven or frequently high-load vehicles. VW internal field data from 2022 indicated a measurable uptick in HPFP-related camshaft replacements before 60,000 km in pre-late-2022 builds, while UK DVSA records show minimal emissions-related MOT failures due to robust GPF and catalyst design. Sustained high-RPM operation without adequate oil quality accelerates wear, making correct oil specification and driving pattern critical.

High-pressure fuel pump (HPFP) cam lobe wear
Symptoms: Hard starts, misfires under load, P0087/P0090 fuel rail pressure codes, metallic ticking from cam cover.
Cause: Insufficient lubrication of HPFP drive cam lobe leading to spalling; exacerbated by extended oil intervals, non-spec oil, or frequent high-RPM operation.
Fix: Replace HPFP with latest revision (06K 127 025 J) and inspect/replace camshaft if lobe damage is present per VW SIB 2021‑04‑03.
Gasoline particulate filter (GPF) saturation
Symptoms: Reduced power, frequent regeneration cycles, exhaust odor, DTCs P2002/P2003.
Cause: Short-trip driving prevents passive GPF regeneration; soot accumulates beyond capacity.
Fix: Perform forced regeneration via diagnostics; if saturation exceeds 80%, replace GPF assembly per OEM procedure.
Turbocharger wastegate rattle
Symptoms: Intermittent rattle at 2,000–3,000 rpm under light load, boost fluctuations, occasional limp mode.
Cause: Wastegate arm bushing wear in IHI IS38 turbo; design susceptible to thermal cycling fatigue.
Fix: Install revised wastegate actuator or replace turbo with updated core per OEM procedure; recalibrate boost control post-repair.
PCV (Crankcase Ventilation) diaphragm rupture
Symptoms: Oil consumption, vacuum leak codes (P0171/P0174), oil mist in intake tract, rough idle.
Cause: Age-related hardening of diaphragm in integrated PCV valve (located in valve cover); pressure spikes accelerate failure.
Fix: Replace entire valve cover assembly with updated PCV design; verify crankcase pressure post-repair.
