Known issues to watch for

The most common problems reported on the Peugeot 508, ranked by severity.

major
Timing chain issues (Mk1)
The EP6 1.6 THP engine uses a single-row timing chain that stretches prematurely due to inadequate oil change intervals and design limitations.
major
DPF blockage and regeneration issues (Mk1)
The diesel particulate filter (DPF) on DV6 1.6 HDi and DW10 2.0 HDi engines blocks with soot when used primarily for short journeys or stop-start driving.
major
Turbocharger failure (Mk1)
The DW12 2.2 HDi engine uses a variable geometry turbocharger that fails due to carbon build-up in the variable vane mechanism and bearing wear from oil contamination.
minor
CV joint boot deterioration
The CV joint boots on diesel variants deteriorate at 64.3x the fleet average rate, with the highest failure rate occurring unusually early at 20,000-40,000 miles.
