Launched in 2019, the 1.5-litre PSA DV5 quickly became the engine that powered not only vehicles for the firm’s newly rebranded car lines, Citroën and Peugeot, but from Ford and, ultimately, Toyota, too. By 2020, more than one million vehicles powered by the DV5 were driving on roads all over the world. Yet, like many of today’s diesel and gasoline engines designed to meet ever-stringent emissions standards, the early DV5s face their challenges.

Mechanics and vehicle owners have experienced premature wear in critical components of the DV5, particularly the camshaft sprockets and timing chain. These primarily appear in models equipped with the 7mm timing chain setup.

In this article we'll learn about the problems with the DV5 engine and examine the solution by upgrading to an 8mm camshaft kit from BGA, which will improve the engine’s life and enhance its performance.

Understanding the DV5 Engine’s Challenges

The primary purpose of the PSA-produced turbocharged 8- and 16-valve DV5 engine was to meet strict Euro 6.2 emissions regulations without compromising performance.

Exhaust Gas Recirculation (EGR) and Diesel Particulate Filters (DPF) played crucial roles in reducing emissions and improving fuel economy. However, these systems inadvertently contributed to the accumulation of soot particles within the engine. As often happens in the automotive industry, solving one problem can introduce another.

For vehicles manufactured between 2019 and early 2023, this internal buildup leads to significant wear in the 7mm pitch timing chain and integrated camshaft sprockets. The 7mm chain has thinner plates than the 8mm chain, and a lower tensile strength, so it’s more prone to stretching and fatigue fractures. This stretching (wear) can then damage the chain itself and cause additional wear of the sprockets, which can result in catastrophic failure.

Common Problems Noted:

• Worn Camshaft Sprockets: Stretching and misalignment will cause the tooth profile to wear prematurely.
  
• Fatigue Fractures: Repeated strain on worn sprockets can cause fractures that will ultimately affect the entire engine.
  
• Reduced Engine Performance and Efficiency: These mechanical problems most often lead to reduced performance and a much higher incidence of breakdown, often leading to expensive repair bills.
  

And no matter how well customers do their part (use recommended factory maintenance), the limitations related to the 7mm setup can eventually lead to an engine defect. This reality has led many in the automotive community to pursue more reliable options.

Wilmink Engine Parts: Providing the Solution

Due to recognizing the problems with their design and, more customer complaints, PSA made a significant change in early 2023: The chain and sprockets of the distribution were changed from 7mm to 8mm. The new 8mm chain wasn't just a minor tweak. The chain and sprockets are not only expanded but also stronger, which results in enhanced tensile strength. Because of this update, the system’s overall durability significantly improved.

Wilmink Engine Parts saw a need for current owners to have a repair option and offers a range of camshaft kits from BGA (BG Automotive). By supplying these BGA kits, Wilmink Engine Parts provides in the supply of quality components that are needed to replace or upgrade the existing system.
