Peugeot 208 Mk1 1.2 PureTech 82bhp — Timing Belt in Oil Failure (Wet Belt)

The 1.2 PureTech engine uses a 'wet belt' timing system — the belt runs in engine oil. This reduces noise but the belt degrades faster than a conventional dry belt. PSA extended the replacement interval, but early failures occurred.

Catastrophic internal damage on failure
P0016/P0017 if belt slips rather than snaps

Root Cause

The wet belt degrades faster when oil is contaminated or at incorrect level. PSA revised the service interval but early 2012-2016 engines have experienced premature failures.

How To Fix

Replace wet belt kit at 60,000 miles or 5 years — do not extend
Ensure correct oil specification (PSA B71 2312) is used — incorrect oil destroys the belt
Cost: £350-600 fitted
This is the single most important maintenance item on the PureTech

The PureTech 1.2 engine has a documented issue with excessive oil consumption on early units. PSA introduced a revised piston ring specification to address the problem.
