The Vauxhall F9Q 772 is a 1,461 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features common‑rail direct injection, a fixed‑geometry turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 66 kW (90 PS) and 220 Nm of torque, prioritising urban efficiency and low-end responsiveness.
Fitted to models such as the Corsa D, Meriva B, and Astra J—including the 1.3 CDTi variants—the F9Q 772 was engineered for entry-level diesel performance with low CO₂ output. Emissions compliance was achieved through exhaust gas recirculation (EGR) and a diesel oxidation catalyst (DOC), enabling Euro 5 compliance across all production years.
One documented concern is high-pressure fuel pump (HPFP) drive shaft wear, highlighted in Vauxhall Service Bulletin PI0528. This is often linked to marginal lubricity in ultra-low-sulfur diesel and thermal stress during repeated short trips. From 2013, Vauxhall introduced revised HPFP shaft hardening and updated camshaft drive lobes to reduce premature wear.
All production years (2010–2018) meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/3891).
The Vauxhall F9Q 772 is a 1,461 cc inline‑four turbo‑diesel engineered for supermini and compact models (2010–2018). It combines common‑rail direct injection with a fixed‑geometry turbocharger to deliver strong low‑rpm torque and urban fuel economy. Designed to meet Euro 5, it balances affordability with emissions control.

The fixed-geometry turbo provides predictable low-RPM torque ideal for city driving but requires strict adherence to 15,000 km oil change intervals using DEXOS2 5W-30 to protect the high-pressure fuel pump and timing chain. Ultra-low-sulfur diesel (EN 590) is mandatory; biodiesel blends above B7 are not recommended. Repeated short trips accelerate HPFP drive shaft wear due to inadequate lubrication—addressed in Vauxhall SIB PI0528. The front-mounted timing chain is considered lifetime but relies on clean oil; sludge from neglected changes may impair tensioner function. EGR systems should be inspected periodically to prevent carbon buildup and limp-mode events.
Oil Specs: Requires DEXOS2 5W-30 (ACEA C3) specification (Vauxhall Owner's Manual 2011).
Emissions: Euro 5 certification applies to all 2010–2018 F9Q 772 engines (VCA Type Approval #VCA/EMS/3891).
Power Ratings: Measured under SAE J1349 standards. Output assumes EN 590 diesel fuel (Vauxhall TIS Doc. TIS-F9Q772-04).

The Vauxhall F9Q 772 was used across Vauxhall's Corsa D, Meriva B, and Astra J platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Astra J for NVH control and modified airbox routing in the Corsa D—and from 2013 the Meriva B adopted updated HPFP hardware, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crank pulley (Vauxhall TIS TIS-F9Q772-06). The 7th VIN digit for F9Q applications is 'F'. All units feature black valve covers with integrated coil packs and a Garrett GT1241 turbo with fixed geometry. Critical differentiation from earlier 1.7 CDTi (A17DTR): F9Q 772 uses a Bosch CP1 high-pressure pump driven directly off the camshaft and lacks balance shafts. Service parts for HPFP (pre- and post-2013) are not interchangeable due to shaft hardening changes per Vauxhall SIB PI0528.
The F9Q 772's primary reliability risk is high-pressure fuel pump (HPFP) drive shaft wear under repeated short-trip use. Vauxhall internal field data (2014) indicated elevated HPFP replacement rates before 80,000 km in urban fleets, while UK DVSA records show minimal emissions-related MOT failures linked to this engine. Thermal cycling and fuel lubricity make DEXOS2 oil and fuel quality critical.
