The Volkswagen CLHA is a 1,498 cc, inline‑three 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 110 kW (150 PS) and 250 Nm of torque, with responsive low‑end delivery enabled by its low‑inertia turbocharger and cylinder deactivation (ACT) system.
Fitted to models such as the Mk8 Golf, T — Roc, T — Cross, and Audi A3 (8Y), the CLHA was en…
All production years (2019–2024) meet Euro 6d full compliance across markets (VCA UK Type Approval #VCA/EMS/6215).
The Volkswagen CLHA is a 1,498 cc inline‑three turbocharged petrol engine engineered for compact hatchbacks and SUVs (2019–2024). It combines direct injection with a low-inertia turbocharger and active cylinder management to deliver responsive low-end torque and reduced emissions. Designed to meet Euro 6d full emissions standards, it balances urban efficiency with everyday drivability.

The Volkswagen CLHA was used across Volkswagen's Mk8 platform with transverse mounting and shared within the Volkswagen Group. This engine received platform-specific adaptations—revised engine mounts in the T-Roc and updated cooling in the Golf—and from 2021 the facelifted T-Cross adopted minor ECU and emissions updates, creating minor calibration limits. Partnerships allowed Audi and SEAT to use variants of this engine in compact models. All adaptations are documented in OEM technical bulletins.
The CLHA's primary reliability risk is high-pressure fuel pump cam follower wear, with elevated incidence in vehicles using RON 95 fuel or extended oil intervals. Volkswagen internal data from 2021 indicated increased HPFP-related warranty claims for pre-2021 builds, while UK DVSA MOT records show secondary issues related to GPF clogging in low-mileage urban use. Consistent use of premium fuel and correct oil specification is critical to mitigate wear.
Analysis derived from Volkswagen technical bulletins (2019–2024) and UK DVSA failure statistics (2020–2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The CLHA offers excellent efficiency and smooth torque delivery, but early units (2019–2020) are prone to HPFP cam follower wear if RON 95 fuel or incorrect oil is used. Post-2021 revisions improved durability. Regular oil changes with VW 504 00/507 00 spec and use of RON 98 fuel significantly enhance longevity.
Top issues include HPFP cam follower wear, GPF clogging in low-mileage use, coolant housing leaks, and intake valve carbon buildup. These are documented in VW service bulletins and supported by DVSA MOT data on emissions-related failures.
The CLHA powers the Golf (Mk8, 2019–2024), T-Roc (2019–2024), T-Cross (2019–2024), and was shared with Audi A3 (8Y). All are EA211 evo2 1.5 TSI variants rated at 150 PS with active cylinder management.
Yes. The CLHA responds well to ECU remapping, with stage 1 typically yielding 180–190 PS. Stock internals support up to ~210 PS with supporting mods (intercooler, exhaust). However, HPFP and cam follower upgrades are recommended beyond stage 1 to ensure reliability.
In a Golf 1.5 TSI, expect ~5.8 L/100km (49 mpg UK) combined under normal driving. Aggressive use can exceed 8.0 L/100km, while steady motorway cruising may drop to ~4.8 L/100km. Real-world figures average 45–52 mpg UK depending on driving style and conditions.
Yes. The CLHA is an interference engine. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the chain is designed as lifetime and rarely fails if oil is maintained.
Volkswagen specifies 0W‑20 synthetic oil meeting VW 504 00 or 507 00 standards. This is critical for cam follower and HPFP protection. Oil changes every 10,000–15,000 km (or annually) are recommended, especially with spirited driving.
