Timing chain rattle / replacement
A fairly common fault we see on R56 car’s is an engine timing chain rattle, mainly from a cold start due to a weak timing chain tensioner. This is often described on the internet as the ‘death rattle’, as a broken timing chain can cause severe engine damage.
However this doesn’t always mean an expensive repair, if caught early enough the initial fix is a new revised Car timing chain tensioner which can cure the issue and prevent any engine damage. If this doesn’t cure the rattle then the next step would be to replace the full timing chain kit including new chain guides. This is because the chain may have stretched over time and broken its guides due to the lack of tension.
