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 responsive torque and motorway stability. Emissions compliance was achieved through exhaust gas recirculation (EGR) and oxidation catalysts, allowing Euro 4 compliance across all production years.
One documented concern is high-pressure fuel pump (HPFP) failure due to insufficient lubrication from low-sulfur diesel or extended service intervals. This issue is referenced in Vauxhall Service Bulletin 09‑034, which notes premature wear in Bosch CP3-based pumps. Later revisions improved filtration and rail pressure control.
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 fixed-geometry turbo provides predictable mid-range response but requires consistent oil changes every 15,000 km to protect the high-pressure fuel pump and timing chain. GM Dexos2 (5W-30) oil is essential due to its low SAPS formulation, which reduces EGR and catalyst fouling. Extended idling or frequent short trips accelerate HPFP wear—per Vauxhall SIB 09 034—and may cause rail pressure faults. Bosch CP3 pumps demand ultra-low-sulfur diesel (EN 590) to maintain lubricity. EGR coolers should be inspected for internal leaks, which can cause coolant contamination and white smoke.
Oil Specs: Requires GM Dexos2 (5W-30) specification (Vauxhall SIB 08 022). Meets ACEA C3 but adds OEM-specific shear stability.
Emissions: Euro 4 certification applies to all 2006–2010 Y22DTR models (VCA Type Approval #VCA/EMS/5678). No Euro 5 variants were produced.
Power Ratings: Measured under SAE J1349 standards. Power output assumes EN 590 diesel with ≤10 ppm sulfur (Vauxhall TIS Doc. VD2301).

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.
Locate the engine code stamped on the front timing cover near the crank pulley (Vauxhall TIS VD2206). The 8th VIN digit indicates engine family ('Y' for Y22 series). All Y22DTR units feature a black plastic valve cover with '2.2 CDTi' branding. Critical differentiation from petrol Y22XE: Y22DTR has a turbocharger on the exhaust manifold and a high-pressure fuel rail on the cylinder head. Bosch EDC16C39 ECU is mounted near the battery. Service parts for HPFP require production date verification—units before 06/2008 use different inlet filters per Vauxhall SIB 09 034.
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.
Analysis derived from Vauxhall technical bulletins (2008–2012) and UK DVSA failure statistics (2014–2023). Repair procedures should follow manufacturer guidelines.
