LOL, mines currently in the garage at the moment having something to do with its Timing chain at 22k, terrible timing chain rattle and its got BMW stumped.

Its not the chain, its not the tensioner, but they are sure its the Timing chain.

Its an R56 - 2007 - on a 57 plate, its done 22k miles in 9 months

Should have it back today - new top end - timing chain snapped due to a tensioner failure.

The 2 I did before I left the dealer were the timing chain tensioner at fault causing chain failure, the reason for them failing was loss of oil to the tensioner or the modified tensioner hadnt located into the chain guide correctly which puts the chain at maximum tension....snap
