A quick update to mine, I did a service recently and as I said I would, checked the bolts for tightness.

Eight out of the twenty bearing cap bolts were below the 8Nm they should have been and some were up to a full turn loose.

The engine had developed a slight rattle and this has quietened it down.

Check your bolts ASAP guys just for peace of mind at the very least, it doesn't take long to do.
