The Vauxhall A17DTF is a 1,686 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features a dual overhead camshaft (DOHC) 16‑valve layout with common‑rail direct fuel injection and a variable geometry turbocharger (VGT). In standard form it delivered 96 kW (130 PS) at 4,000 rpm and 300 Nm of torque at 2,000–2,500 rpm, providing strong low‑end pull ideal for urban and motorway driving.
Fitted to models such as the Astra J, Corsa D, and Meriva B—includin…
All production years 2010–2018 meet Euro 5 standards .
The Vauxhall A17DTF is a 1,686 cc inline‑four turbo‑diesel engineered for compact hatchbacks and MPVs (2010–2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 5 emissions standards, it balances everyday drivability with fuel economy.

The Vauxhall A17DTF was used across Vauxhall's J30/Z30 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Meriva B and modified airbox routing in the Corsa D—and from 2013 the facelifted Astra J models retained the same engine code but updated ECU calibrations for improved DPF management, creating minor software 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 A17DTF is generally dependable with proper maintenance, but early high-pressure fuel pump wear can occur in high-mileage examples with infrequent oil changes or poor fuel quality. Using GM‑LL‑B‑025 oil and adhering to 15,000 km service intervals greatly reduces risk. Well-maintained units often exceed 180,000 km without major issues.
High-pressure fuel pump drive wear is the most serious issue, followed by DPF regeneration failures, EGR carbon buildup, and cam cover oil leaks. These are documented in Vauxhall SIBs and commonly observed in UK MOT failure data. Regular servicing and proper driving habits mitigate most concerns.
The A17DTF powered the Astra J (2010–2015), Corsa D (2011–2014), and Meriva B (2010–2017) in 1.7 CDTi 130 trims. It was exclusive to Vauxhall/Opel and not licensed to other manufacturers. All variants meet Euro 5 emissions.
Modest gains are possible via ECU remap (+10–15 kW) and exhaust upgrades, but the CP4.2 pump and turbo limit significant tuning. Most owners prioritize reliability over performance due to the engine’s sensitivity to fuel quality and maintenance.
In an Astra J 1.7 CDTi, expect ~5.8 L/100km (city) and ~4.0 L/100km (highway), or about 52 mpg UK combined. Real-world mixed driving typically yields 48–55 mpg (UK), depending on condition and driving style. Economy is competitive for its era.
Yes. The A17DTF is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause severe internal damage. However, the chain is robust and rarely fails if maintained; no widespread timing-related failures are documented.
Vauxhall specifies SAE 5W‑30 synthetic oil meeting GM‑LL‑B‑025. Always use a quality oil and change every 15,000 km or 12 months to protect the fuel pump drive and maintain engine longevity.
