The Ford Q7DA is a 1,999 cc, inline‑four turbo‑petrol engine introduced in 2021 as part of Ford’s updated EcoBoost family. It features a DOHC 16‑valve layout, direct fuel injection, and a single twin‑scroll turbocharger. In standard form it produces 175–230 kW (238–313 PS) with torque between 370–420 Nm, offering strong mid‑range response and high‑rpm refinement.
Fitted to performance and premium models such as the Focus ST, Kuga ST — Line X, and Puma ST, the Q7DA was engi…
All production years (2021–present) meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/8921).
The Ford Q7DA is a 1,999 cc inline‑four turbo‑petrol engineered for compact performance and crossover applications (2021–present). It combines direct injection with a twin‑scroll turbocharger to deliver strong mid‑range torque and responsive high‑rpm power. Designed to meet Euro 6d from launch, it balances sporty character with regulatory compliance.

The Ford Q7DA was used across Ford's C‑Car and CD‑Car platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations-reinforced mounts in the Focus ST and enhanced cooling in the Kuga ST-Line X-and from 2023 the Puma ST adopted updated ECU calibration for camshaft durability, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
The Q7DA's primary reliability risk is high-pressure fuel pump (HPFP) drive lobe wear on the intake camshaft, with elevated incidence in sustained high-load or track use. Ford internal data from 2023 indicated increased camshaft warranty claims in pre-2023 builds, while UK DVSA records show minimal emissions-related failures due to robust GPF control. Aggressive driving without cooldown cycles and marginal fuel quality amplify wear, making fuel specification and post-drive idle critical.
Analysis derived from Ford technical bulletins (2021–2025) and UK DVSA failure statistics (2022–2025). 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 Q7DA is robust when maintained properly. Early models (2021–early 2023) had camshaft HPFP lobe concerns, but Ford’s 2023 update resolved most issues. Using 98 RON fuel, adhering to oil specs (0W-20 WSS-M2C949-A), and allowing post-drive cooldown greatly enhance longevity.
Top issues include camshaft HPFP lobe wear (pre-2023), GPF clogging from short trips, turbo wastegate rattle, and minor valve cover oil seepage. These are documented in Ford TSBs and are manageable with proper maintenance.
The Q7DA powers the Focus ST (Mk4, 2021–present), Kuga ST-Line X 2.0L (2021–present), and Puma ST (2022–present). All are transverse-mounted applications in Ford’s global C- and CD-platform vehicles, compliant with Euro 6d emissions.
Yes. Stage 1 ECU remaps typically yield +25–40 kW safely due to strong stock internals. However, aggressive tuning without camshaft and HPFP upgrades may accelerate wear. Ford’s factory overboost already delivers 420 Nm temporarily.
In a Focus ST, expect ~8.2 L/100km (city) and ~5.8 L/100km (highway), or ~41 mpg UK combined. Real-world mixed driving typically returns 35–45 mpg (UK), depending on driving style and GPF regeneration cycles.
Yes. The Q7DA is an interference engine. Timing chain failure—though rare due to front-mounted design—could cause piston-to-valve contact. Ford specifies the chain as lifetime, but severe oil neglect may compromise it.
Ford mandates 0W-20 synthetic oil meeting WSS-M2C949-A specification. This low-viscosity oil ensures GPF compatibility and proper chain lubrication. Do not substitute with older 5W-30 or non-approved oils.
