The Vauxhall D 16 SHL is a 1,598 cc, inline‑four turbo‑diesel engine produced between 2013 and 2018. It features common‑rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivers 95 kW (130 PS) and 300 Nm of torque, with strong low‑rpm pull ideal for urban and motorway driving.
Fitted to models such as the Astra J, Meriva B, and Zafira Tourer C—including the 1.6 CDTi variants—the D 16 SHL was engineered for…
All production years (2013–2018) meet Euro 5b standards .
The Vauxhall D 16 SHL is a 1,598 cc inline‑four turbo‑diesel engineered for compact and MPV models (2013–2018). It combines common‑rail direct injection with a variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 5b, it balances everyday drivability with emissions control.

The Vauxhall D 16 SHL was used across Vauxhall's Astra J, Meriva B, and Zafira Tourer C platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Zafira Tourer for NVH control and modified airbox routing in the Meriva—and from mid‑2015 the Astra J LCI adopted an updated dual‑mass flywheel, creating minor service part distinctions. 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 D 16 SHL offers strong torque and good fuel economy, but early units (2013–mid-2015) had dual-mass flywheel reliability concerns under urban use. Later revisions improved DMF durability. With proper maintenance—especially using DEXOS2 5W-30 oil and quality diesel—most engines exceed 200,000 km without major issues.
Top issues include dual-mass flywheel wear, DPF clogging from short trips, high-pressure fuel pump wear, and EGR cooler leaks. DMF and HPFP problems are addressed in Vauxhall service bulletins PI0631 and TIS-D16SHL-07.
The D 16 SHL powered the Astra J (2013–2018), Meriva B (2013–2017), and Zafira Tourer C (2013–2018) in 1.6 CDTi 130 PS form. It was not used in commercial vehicles or licensed to other manufacturers. All applications are transverse FWD layouts.
Aftermarket ECU tuning is common on the D-16-SHL 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.
In an Astra 1.6 CDTi (130 PS), expect ~5.2 L/100km (city), ~3.8 L/100km (highway), or ~62 mpg UK combined. Real-world mixed driving typically returns 52–58 mpg UK. Economy suffers with short trips due to incomplete DPF regeneration cycles.
Yes. The D 16 SHL is an interference engine. If the timing chain fails (extremely rare due to front-mounted design), piston-to-valve contact will cause catastrophic damage. However, the chain is designed for life-of-engine service with proper oil maintenance.
Vauxhall specifies DEXOS2 5W-30 (ACEA C3) synthetic oil. This low-SAPS formulation protects the turbo, HPFP, and emissions systems. Change intervals should not exceed 15,000 km or 12 months, especially with urban driving.
