Peugeot 508 Replacement Engines
The Peugeot 508 evolved through two key generations from 2007-present, with petrol and diesel engines sharing common architecture across saloon and estate variants. The HDi diesel family suffered EGR cooler failures addressed in Peugeot Service Bulletins, while THP petrol engines required turbocharger replacement after 80,000 miles regardless of body style. All 508 engines used identical mounting systems and shared timing chain components, with HDi units particularly prone to oil pump issues that affected both saloon and estate models equally.
Peugeot 508 Models & Engines Codes
The 508 series utilized two primary engine families across all body styles, with specific variants sharing identical components and failure patterns. Engine codes remained consistent across saloon and estate models throughout production years.
- HDi: 1.6L/2.0L diesel (2007-2018) - EGR cooler failures across all 508 variants
- THP: 1.6L/2.0L petrol (2008-2020) - Turbocharger issues in all 508 body styles
- HDI: 2.2L diesel (2009-2018) - Timing chain problems across 508 range
- EP6: 1.6L petrol (2007-2014) - Timing belt issues in early 508 variants
- EP3: 1.4L petrol (2007-2012) - Head gasket problems across 508 models
All 508 engines used identical mounting configurations regardless of body style, meaning HDi components from saloons fit estates equally. The shared architecture means failure patterns affected all 508 variants equally, with EGR cooler issues in HDi units occurring across the entire model range.
