🔍 Common 1.2 TSI Timing Chain Problems

Many 1.2 TSI owners experience:

  • Rattling noise on cold start – often caused by a stretched chain or weak tensioner
  • Timing correlation faults – usually triggering a check engine light
  • Rough idle or misfiring – due to incorrect valve timing

If you notice any of these signs, it’s time to inspect your timing chain before it fails.
