The Vauxhall Y22DTR is a 2,171 cc, inline‑four turbo‑diesel engine produced between 2006 and 2010. It features common rail direct injection, a fixed — geometry turbocharger, and dual overhead camshafts (DOHC). In standard form it delivered 110 kW (150 PS) and 320 Nm of torque, engineered for balanced performance and towing capability.
Fitted to models such as the Vectra C, Signum, and Zafira B—including the 2.2 CDTi variants—the Y22DTR was designed for drivers needing r…
All production years 2006–2010 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5678).
The Vauxhall Y22DTR is a 2,171 cc inline‑four turbo‑diesel engineered for mid‑size sedans and MPVs (2006–2010). It combines Bosch common‑rail direct injection with a fixed‑geometry turbocharger to deliver strong mid‑range torque and stable highway performance. Designed to meet Euro 4 emissions standards, it balances load-carrying ability with fuel economy.

The Vauxhall Y22DTR was used across Vauxhall's Epsilon platform with transverse mounting and shared with Opel and Saab under GM's global engine strategy. This engine received platform-specific adaptations—reinforced mounts in the Signum and modified cooling in the Zafira B—and from 2008 the facelifted Vectra C LCI models retained the same engine code but with updated ECU calibrations, creating minor software interchange limits. Partnerships allowed Saab's 2.2 TiD units to use identical long blocks. All adaptations are documented in OEM technical bulletins.
The Y22DTR's primary reliability risk is high-pressure fuel pump (HPFP) failure, with elevated incidence in vehicles using inconsistent fuel quality or extended service intervals. Vauxhall internal data from 2011 indicated a significant share of 2006–2008 builds required HPFP replacement before 140,000 km, while UK DVSA MOT records show EGR-related smoke failures in high-mileage Zafira Bs. Short-trip driving and infrequent oil changes accelerate pump and chain wear, making fuel quality and maintenance adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The Y22DTR offers strong torque and good highway manners, but early models (2006–2008) are prone to HPFP and EGR cooler issues. Later builds saw minor improvements. With strict adherence to oil changes (every 15,000 km) and use of quality EN 590 diesel, well-maintained examples can exceed 200,000 km reliably.
Top issues include high-pressure fuel pump failure, EGR cooler leaks causing white smoke, turbo oil seal leaks, and timing chain tensioner wear. These are documented in Vauxhall service bulletins 09‑034 and 08‑022, and frequently appear in UK MOT failure records for Vectra and Zafira models.
The Y22DTR powered the Vectra C (2006–2008), Signum (2006–2008), and Zafira B (2006–2010) as the 2.2 CDTi. It was also used by Opel in identical models and by Saab in the 9‑3 2.2 TiD (2006–2009) under GM’s shared-engine program.
Yes. ECU remaps typically yield +20–30 kW safely on stock hardware, as the internals handle torque well. However, HPFP reliability becomes a limiting factor—supporting upgrades (lift pump, filtration) are recommended. Always use high-quality diesel and maintain oil to avoid overstressing components.
In a Vectra 2.2 CDTi, expect ~6.8 L/100km (city) and ~4.7 L/100km (highway), or about 45 mpg UK combined. Real-world mixed driving typically returns 40–50 mpg (UK), depending on condition, driving style, and EGR/DPF health.
Yes. The Y22DTR is an interference engine. If the timing chain jumps or breaks, piston-to-valve contact can cause catastrophic internal damage. Prompt attention to chain rattle or correlation faults is essential to prevent engine failure.
Vauxhall specifies GM Dexos2 5W‑30 synthetic oil. This low-SAPS formulation protects the EGR system and turbocharger. Oil changes every 15,000 km (or annually) are critical to prevent HPFP and chain wear, especially in stop-start or short-trip driving.
