Hi Greydog,
thanks for message.
i driving 2011, 520d 184 bhp. Now it has 130000km but the noise is since o got it so around 120000. I heard this accidentally because you won’t hear it when door are closed. I bought it on warranty so they told me is nothing out of the source but I don’t believe them. I had already issues with steering and they had to replace steering racks:(
i attach file but hard to hear on the phone.
regards
