Symptoms

Very loud rattling/clicking noise on cold start
'Check Anti-Pollution System' warning light
P0011 or P0012 camshaft timing fault codes
Rough idle

Root Cause

The single-row timing chain is weak, and the hydraulic tensioner loses pressure over time, especially if oil changes are neglected or the wrong grade of oil is used.

How To Fix

Confirm the noise is the chain and not just the loud high-pressure fuel pump (which is normal).
Replacement of the timing chain, tensioner, and guides is required.
Must be done by a professional with locking tools.
