Thanks for all the responses, very much appreciated.

I will head out to Makara on my next road hunting trip, hopefully that does it.

In terms of judder bars, are you meaning the ones in the paint on the side of the road?  On those there is too much noise from the judder bars to be able to distinguish the rattle.

Thanks Coop. 

I did try that road but unfortunately the surface on that road is not as rough as what is on the open road between towns, so it does not cause the rattle.

Hello everyone,  this is my first post here.   I am hoping to tap into some local knowledge to help me get a problem solved.

I am basically one very happy chap.  With the help of my wonderful lady and many years of saving I am now the owner of a 2015 F10 M5.  I got it in a private sale up in Auckland a couple of weeks ago and had a fantastic road trip back to Wellington.  

As fantastic as the car was to drive on the trip back, a problem manifested on the open road that is rather annoying.  On those “chip seal” roads that you typically find on the open road between towns, there is a very loud rattle coming from the steering column.  This rattle is not evident on normal inner city/town asphalt roads or motorways.

I took it in to Winger BMW, and they are happy to get it fixed under warranty, but won’t do anything until they can reproduce the rattle.   I have thus been on the hunt for a stretch of chip seal road within a reasonable distance to Winger BMW.   After several hours of driving around Ngaio, Northland, Newlands and Island Bay areas I have not found what I need.  So far the only bit of road that does the trick is at the bottom of the Rimutaka hill.   That is just too far away.

This is where I am hoping the members of this forum may be able to help.  I am looking for a stretch of chip seal road as close to Wellington City as possible, ideally with at least a 70KM speed limit, but any stretch should do.

Any help would be very much appreciated.

Regards

Phil
