First post on here!

I have a 320d 2011 plate. 127k on the clock and had it since 70k. I’ve noticed recently the engine noise is getting louder and I can hear (ever so slightly) the distinct noise of metal louder from the passenger side than drivers side. It’s most noticeable when starting on a cold day.

From the research I’ve done I think this is my timing belt loosening but I’m hoping someone here has a very similar problem and less expensive fix!

My engine code is apparently that of which is a known fault with these and I’ve seemed to have got lucky getting such a long run on it.

I have a recording of the noise but don’t know how to post it here.
