1.2 TSI timing chain tensioner failure

Question

Accepted Answer

The EA111 1.2 TSI engine used in the Polo (and shared across the VAG group) has a known weak timing chain tensioner that can fail suddenly, which in the worst case allows the chain to jump and cause serious engine damage. Typical fix: Timing chain kit replacement (chain, tensioner, guides). VW ran a technical campaign on some affected cars, worth checking service history.
