The Volkswagen DKLC is a 1,498 cc, inline‑four turbocharged petrol engine produced between 2019 and 2023. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and a single twin‑scroll turbocharger. In standard form it delivers 110 kW (150 PS) and 250 Nm of torque, engineered for responsive urban performance and efficient highway cruising.
Fitted to models such as the Mk8 Golf, T-Roc, and Škoda Kamiq, including variants like the 1.5 TSI 150 PS, the DKLC was designed for drivers prioritising fuel economy, refined drivability, and compliance with the latest emissions standards. Emissions control is achieved through a close‑coupled three‑way catalytic converter, dual lambda sensors, and a gasoline particulate filter (GPF), meeting Euro 6d from launch.
One documented concern is premature wear of the high‑pressure fuel pump (HPFP) drive lobe on the intake camshaft, highlighted in Volkswagen Service Technical Bulletin ST07‑21‑02. This issue stems from marginal surface hardening on early production camshafts under high thermal and mechanical stress. From mid‑2021, revised camshaft metallurgy and updated HPFP units were introduced to improve durability.
Production years 2019–2023 meet Euro 6d standards across all markets (VCA UK Type Approval #VCA/EMS/9317).
The Volkswagen DKLC is a 1,498 cc inline‑four turbocharged petrol engine engineered for compact and subcompact models (2019–2023). It combines Bosch HDEV6 direct injection with a twin‑scroll turbocharger to deliver strong low‑end torque and refined efficiency. Designed to meet Euro 6d standards, it balances performance with stringent emissions compliance.

The BorgWarner B03 twin‑scroll turbo provides immediate throttle response ideal for mixed driving but requires adherence to 15,000 km or 12‑month oil change intervals using VW 508 00/509 00 oil to protect the high‑pressure fuel pump and camshaft drive lobe. Premium 95 RON petrol is mandatory; 98 RON is recommended for optimal performance and injector longevity. Early camshafts (pre‑mid‑2021) are prone to HPFP lobe wear—symptoms include metallic ticking and fuel pressure faults. Replace with updated camshaft P/N 05E 109 021 H per ST07‑21‑02 if wear is detected. The GPF requires sufficient highway driving for passive regeneration; frequent short trips may trigger saturation warnings.
Oil Specs: Requires VW 508 00 or 509 00 (0W‑20) low‑SAPS oil (Volkswagen TIS 05E‑1001). Not interchangeable with 502 00 or ACEA C5 alone.
Emissions: Euro 6d applies to all production years (VCA Type Approval #VCA/EMS/9317).
Power Ratings: Measured under ISO 1585 standards. Output verified on 95 RON petrol (Volkswagen PT‑2023).

ISO 1585: Road vehicles — Engine test code
The Volkswagen DKLC was used across Volkswagen's Mk8 platform with transverse mounting and shared with Škoda and SEAT under the MQB Evo architecture. This engine received platform-specific adaptations—revised engine mounts in the T-Roc and modified exhaust routing in the Golf VIII—and from mid‑2021 the introduction of updated camshaft metallurgy, creating minor ECU and sensor interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the oil filter housing (Volkswagen TIS 05E‑1005). The 7th VIN digit is 'E' for 1.5L TSI engines; confirm DKLC via ECU part number (05E 906 019 AM) or diagnostic scan. Pre-mid‑2021 camshafts use P/N 05E 109 021 F; post-mid‑2021 units use P/N 05E 109 021 H with hardened HPFP lobe. Critical differentiation from DNUA: DKLC is 150 PS with GPF; DNUA is 130 PS with different boost mapping. Service parts for camshaft and HPFP are not interchangeable across model years without verification (Volkswagen STB 07‑21‑02).
The DKLC's primary reliability risk is high-pressure fuel pump cam lobe wear and gasoline particulate filter (GPF) clogging, with elevated incidence in urban stop-start use. Volkswagen internal data from 2022 indicated a notable rate of HPFP-related DTCs in vehicles under 60,000 km, while UK DVSA MOT records show increased GPF-related failures in high-mileage DKLC engines. Frequent short trips and low-quality fuel accelerate carbon accumulation, making fuel quality and driving pattern critical.
