The Vauxhall Z17DTR is a 1,686 cc, inline‑four turbo‑charged diesel engine produced between 2006 and 2013. It features dual overhead camshafts (DOHC), 16 valves, and common‑rail direct fuel injection. In standard form it delivered 81 kW (110 PS) at 4,000 rpm and 250 Nm of torque at 2,000 rpm, offering strong low‑end pull for compact and mid‑size applications.
Fitted to models such as the Astra H, Zafira B, and Corsa D, the Z17DTR was engineered for cost‑effective urban comm…
Production years 2006–2009 meet Euro 4 standards; 2010–2013 models meet Euro 5 standards .
The Vauxhall Z17DTR is a 1,686 cc inline‑four turbo‑diesel engineered for compact and mid‑size family vehicles (2006–2013). It combines common‑rail direct injection with a fixed‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 4 (and later Euro 5) emissions standards, it balances drivability with moderate fuel consumption.

The Vauxhall Z17DTR was used across Vauxhall's Astra H, Zafira B, and Corsa D platforms with transverse mounting and shared with Opel under GM’s global diesel strategy. This engine received platform-specific adaptations—reinforced engine mounts in the Zafira B and revised intake manifolds in the Astra H—and from 2010 the Euro 5 update introduced camshaft and ECU changes, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The Z17DTR offers strong torque and good economy but has a known risk of high-pressure fuel pump cam follower wear if oil changes are delayed. Early models (2006–2009) are more susceptible; Euro 5 variants (2010–2013) feature improved camshafts. With strict 15,000 km oil intervals using GM‑LL‑B‑025 oil, many engines exceed 200,000 km reliably.
Top issues include cam follower wear leading to fuel pump failure, DPF clogging from short trips, EGR valve carbon buildup, and turbo oil seal leaks. These are documented in Vauxhall TSB‑06‑08‑12 and recurring UK MOT advisories related to emissions and smoke.
The Z17DTR powered the Astra H (2006–2013), Zafira B (2006–2011), and Corsa D (2007–2013) in 1.7 CDTi variants. It was also used in Opel equivalents (Astra, Zafira, Corsa) across Europe under GM’s shared diesel platform.
Aftermarket ECU tuning is common on the Z-17-DTR platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Excellent for its class. In an Astra H 1.7 CDTi, expect ~5.9 L/100km (city), ~4.1 L/100km (highway), or ~48 mpg UK combined. Real-world mixed driving typically yields 45–50 mpg UK. Economy degrades if DPF or EGR systems are malfunctioning.
Yes. The Z17DTR is an interference engine. If the timing chain fails (rare but possible), pistons can contact open valves, causing catastrophic damage. However, the chain is robust and designed to last the engine’s lifetime with proper oil maintenance.
Vauxhall specifies SAE 5W‑30 synthetic oil meeting GM‑LL‑B‑025 standard. Always use a quality ACEA C3‑compliant oil designed for diesel engines with DPF and change every 15,000 km or 12 months to protect the fuel pump cam follower and aftertreatment systems.
